“The information you have is not the information you want. The information you want is not the information you need. The information you need is not the information you can obtain. The information you can obtain costs more than you want to pay.” -– Finagle’s Laws of Information from “Against the Gods: The Remarkable Story of Risk” by Peter Bernstein

“Effective communication is the key to successful software projects.” – Gojko Adzic in "Bridging the Communication Gap: Specification by Example and Agile Acceptance Testing"

“Quality has to be caused, not controlled” – Philip Crosby
“For acceptance tests to be effective, they have to be automated but also have to be human readable. And ‘human’ in this case also includes those who cannot decrypt the Matrix code on the fly.” – Gojko Adzic in "Bridging the Communication Gap: Specification by Example and Agile Acceptance Testing"
“Unit tests will insure the code is built right, and acceptance tests insure the right code is built’.” – Andy Dassing

“Motivating your people is always more important than establishing your own favorite processes.” – Jurgen Appelo in “Management 3.0”.
“What can I do to help you do your best work?” - Scott Berkun in “Making Things Happen: Mastering Project Management”
“These motivational accessories, as they are called (including slogan coffee mugs, plaques, pins, key chains, and awards), are a triumph of form over substance. They seem to extol the importance of Quality, Leadership, Creativity, Teamwork, Loyalty, and a host of other organizational virtues. But they do so in such simplistic terms as to send an entirely different message: Management here believes that these virtues can be improved with posters rather than by hard work and managerial talent.” – Tom DeMarco and Tim Lister in “Peopleware”
“If a system is to be stable the number of states of its control mechanism must be greater than or equal to the number of states in the system being controlled … Simply put, this law states that a system can be controlled by another system only when the other system is just as complex as or more complex than the first one.” – W. Ross Ashby's “Law of Requisite Variety”. If you want to control people, you need a system as least as complex as people.

“From the beginning of the universe, everything in it was shaped by self-organization.” – Jurgen Appelo in “Management 3.0”.
“Innovation happens to be a concept at the heart of complexity science. Researchers found that complex adaptive systems actively seek a position between order and chaos because innovation and adaptation are maximized when systems are at “the edge of chaos”” – Jurgen Appelo in “Management 3.0”.
“There is plenty of value in root-cause analysis. I mean that root-cause analysis can only look to the past. It helps you to fix problems that have already happened, so they won’t happen again. But it won’t help you to predict what will go wrong in the future.” – Jurgen Appelo in “Management 3.0”.

Improvements always make those at the top of the heap look inept. Who enjoys appearing inept?” – Frank Herbert in “Heretics of Dune”.
“Never accept a traffic-light status report in a portfolio evaluation meeting. The traffic light provides no data for your decision.” – Johanna Rothmans in Manage Your Project Portfolio. The thinking here is that you are about to make “going forward decisions” and so this backward looking status doesn't help with that.
“The big rule of project portfolio management is that you never make a big decision where you commit an entire organization to a huge project for a long time. I define huge as more than 50 percent of your people, and I define long as more than three months.” – Johanna Rothmans in Manage Your Project Portfolio
“In all honesty, the only projects that are too risky to start are the ones that can’t return anything you can see in a few weeks.” – Johanna Rothmans in Manage Your Project Portfolio
“Project teams don’t work for many reasons. One common way is to have a person who doesn’t work well with others — an unjeller” – Johanna Rothmans in Manage Your Project Portfolio. I think we've all met the “unjeller”.
“Often, innovation is a capacity problem - there needs to be slack in the system to innovate” – Hans Samios
“If you don’t know who your customers are or you haven’t talked to them in six months, you will not deliver what your customers want. This is a slow but sure way to create a doomed project.” – Johanna Rothmans in Manage Your Project Portfolio
“Commitment is not a 'We’ll give you part of what you need, but …' It’s a full commitment.” – Johanna Rothmans in Manage Your Project Portfolio on staffing the most important projects first.
“If you are trying to staff a project with people who are working part-time on your project and part-time on other projects, you have an uncommitted project. That’s because the cost of context switching will erase any potential ability to focus on this project. Don’t partially commit to a project; that’s a lack of commitment. Be honest. Take that project off the committed list. You may have to move the project to the parking lot. You might have to transform it. But never make a partial commitment.” – Johanna Rothmans in Manage Your Project Portfolio
“Commitment is not a 'We’ll give you part of what you need, but …' It’s a full commitment.” – Johanna Rothmans in Manage Your Project Portfolio
“Think in terms of value. Producers create value, but customers define it.” – Johanna Rothmans in Manage Your Project Portfolio on defining value streams
“The fewer number of active projects you have, the less competition the projects have for the same people. That lack of competition for people allows them to finish projects faster.” – Johanna Rothmans in Manage Your Project Portfolio
“The more frequently the projects deliver something you can see, the easier it will be to manage the project and to manage the project portfolio.” – Johanna Rothmans in Manage Your Project Portfolio
“Your customers want your products to be filled with great features that are well-tested and run smoothly. They don’t care about your projects, and they certainly don’t care about your portfolio. Your customers care about your products.” – Johanna Rothmans in Manage Your Project Portfolio
“I believe that inside every complex solution is a simple solution trying to get out” – Ron Jeffries
“Integrative Thinking is the ability to constructively face the tensions of opposing models, and instead of choosing one at the expense of the other, generating a creative resolution of the tension in the form of a new model that contains elements of the both models, but is superior to each” – Rotman.
“Commanders know the objective; leaders grasp the direction. Commanders dictate; leaders influence. Controllers demand; collaborators facilitate. Controllers micro-manage; collaborators encourage. Managers who embrace the leadership-collaboration model understand their primary role is to set direction, to provide guidance, and to facilitate connecting people and teams.” – Jim Highsmith.
“Adaptive leaders lead teams, non-adaptive ones manage tasks.” – Jim Highsmith.
“A traditional manager focuses on following the plan with minimal changes, whereas an agile leader focuses on adapting successfully to inevitable changes.” – Jim Highsmith.
“Everyone tries to do too much: solve too many problems, build products with too many features. We say ‘no’ to almost everything. If you include every decent idea that comes along, you’ll just wind up with a half-assed version of your product. What you want to do is build half a product that kicks ass.” – Founders of 37signals in (Taylor, 2011).
“A number of studies have shown that 50% or more of functionality delivered is rarely or never used … This leads to the conclusion that scope is a very poor project control mechanism — we should be using value.” – Jim Highsmith

“People are not afraid of the failure, they're afraid of the blame.” – Seth Grodin

“Leading as a gardener meant that I kept the Task Force focused on clearly articulated priorities by explicitly talking about them and by leading by example.” – General Stanley McChrystal in “Team of Teams”
“The role of the senior leader was no longer that of controlling puppet master, but rather that of an empathetic crafter of culture.” – General Stanley McChrystal in “Team of Teams”
“I found that, by ignoring the Perry Principle and containing my desire to micromanage, I flipped a switch in my subordinates: they had always taken things seriously, but now they acquired a gravitas that they had not had before. It is one thing to look at a situation and make a recommendation to a senior leader about whether or not to authorize a strike. Psychologically, it is an entirely different experience to be charged with making that decision.” – General Stanley McChrystal in “Team of Teams”. And related …
“More important, and more surprising, we found that, even as speed increased and we pushed authority further down, the quality of decisions actually went up.” – General Stanley McChrystal in “Team of Teams”
“I was most effective when I supervised processes — from intelligence operations to the prioritization of resources—ensuring that we avoided the silos or bureaucracy that doomed agility, rather than making individual operational decisions.” – General Stanley McChrystal in “Team of Teams”
“I began to reconsider the nature of my role as a leader. The wait for my approval was not resulting in any better decisions, and our priority should be reaching the best possible decision that could be made in a time frame that allowed it to be relevant.” – General Stanley McChrystal in “Team of Teams”
“A Bank of America call center … Success is measured by AHT (average call handle time), which ideally should be as low as possible. Pentland gave workers sociometric badges all day for six weeks, and measured levels of interaction and engagement. When he shifted the coffee break system from being individual to being team based, interaction rose and AHT dropped, demonstrating a strong link between interaction and productivity.” – General Stanley McChrystal in “Team of Teams”
“When Pentland surveyed a number of R&D labs, he found that he could predict the labs’ creative output with an extraordinary 87.5 percent accuracy by measuring idea flow.” – General Stanley McChrystal in “Team of Teams”
“However, as interfaces became increasingly important, we realized the potential for bolstering our relationships with our partner agencies by way of a strong linchpin liaison officer (LNO). As it turned out, some of our best LNOs were also some of our best leaders on the battlefield. … Everyone hated removing some of our best operators from the battlefield, but we reaped enormous benefits” – General Stanley McChrystal in “Team of Teams” on the use best people as interfaces taking them away from day to day work - not efficient but effective
“The critical first step was to share our own information widely and be generous with our own people and resources. From there, we hoped that the human relationships we built through that generosity would carry the day.” – General Stanley McChrystal in “Team of Teams”
“I’ve always believed that management’s ability to influence work habits through edict is limited. Ordering something gets it done, perhaps. When you turn your back, though, employees tend to regress to the same old ways.” – Michael Bloomberg
“We don’t know what connections and conversations will prove valuable.” – General Stanley McChrystal in “Team of Teams”
“Teams can bring a measure of adaptability to previously rigid organizations. But these performance improvements have a ceiling as long as adaptable traits are limited to the team level.” – General Stanley McChrystal in “Team of Teams”
“We had to find a way for the organization as a whole to build at scale the same messy connectivity our small teams had mastered so effectively.” – General Stanley McChrystal in “Team of Teams”
“Purpose affirms trust, trust affirms purpose, and together they forge individuals into a working team.” – General Stanley McChrystal in “Team of Teams”
“Their structure — not their plan — was their strategy.” – General Stanley McChrystal in “Team of Teams”
“Great teams consist of individuals who have learned to trust each other. Over time, they have discovered each other’s strengths and weaknesses, enabling them to play as a coordinated whole.” – Amy Edmondson
“In a command, the connections that matter are vertical ties; team building, on the other hand, is all about horizontal connectivity.” – General Stanley McChrystal in “Team of Teams”
“SEAL teams accomplish remarkable feats not simply because of the individual qualifications of their members, but because those members coalesce into a single organism. Such oneness is not inevitable, nor is it a fortunate coincidence. The SEALs forge it methodically and deliberately.” … “The purpose of BUD/S is not to produce super-soldiers. It is to build super teams.” – General Stanley McChrystal in “Team of Teams”
“We needed flexibility but we also needed the advantages of scale that accompany efficiency. We had to find a way to create that adaptability while preserving many of our traditional strengths. This would prove difficult—many of the practices that are most efficient directly limited adaptability” – General Stanley McChrystal in “Team of Teams”
“If we cannot control the volatile tides of change, we can learn to build better boats.” – Zolli
“Efficiency is doing things right; effectiveness is doing the right thing.” – Peter Drucker
““Resilience thinking” is a burgeoning field that attempts to deal in new ways with the new challenges of complexity. In a resilience paradigm, managers accept the reality that they will inevitably confront unpredicted threats; rather than erecting strong, specialized defenses, they create systems that aim to roll with the punches, or even benefit from them.” – General Stanley McChrystal in “Team of Teams”
“Data-rich records can be wonderful for explaining how complex phenomena happened and how they might happen, but they can’t tell us when and where they will happen.” – General Stanley McChrystal in “Team of Teams”
“In such settings, the ritual of strategic planning, which assumes 'the future will be more or less like the present,' is more hindrance than help.” – General Stanley McChrystal in “Team of Teams”
“Frederick Taylor’s managerial solutions were unequivocally designed for complicated problems rather than complex ones.” – General Stanley McChrystal in “Team of Teams”
“Complex systems are fickle and volatile, presenting a broad range of possible outcomes; the type and sheer number of interactions prevent us from making accurate predictions. As a result, treating an ecosystem as though it were a machine with predictable trajectories from input to output is a dangerous folly.” – General Stanley McChrystal in “Team of Teams”, and related …
“The average forecasting error in the U.S. analyst community between 2001 and 2006 was 47 percent over twelve months and 93 percent over twenty-four months. As writer and investor James Montier puts it, 'The evidence on the folly of forecasting is overwhelming . . . frankly the three blind mice have more credibility than any macro-forecaster at seeing what is coming.' In November 2007, economists in the Survey of Professional Forecasters—examining some forty-five thousand economic-data series—foresaw less than a one-in-five-hundred chance of an economic meltdown as severe as the one that would begin one month later.” – General Stanley McChrystal in “Team of Teams”
“In popular culture, the term “butterfly effect” is almost always misused. It has become synonymous with 'leverage' - the idea of a small thing that has a big impact, with the implication that, like a lever, it can be manipulated to a desired end. This misses the point of Lorenz’s insight. The reality is that small things in a complex system may have no effect or a massive one, and it is virtually impossible to know which will turn out to be the case.” – General Stanley McChrystal in “Team of Teams”
“Interconnectedness and the ability to transmit information instantly can endow small groups with unprecedented influence: the garage band, the dorm-room start-up, the viral blogger, and the terrorist cell.” – General Stanley McChrystal in “Team of Teams”
“The pursuit of “efficiency”—getting the most with the least investment of energy, time, or money—was once a laudable goal, but being effective in today’s world is less a question of optimizing for a known (and relatively stable) set of variables than responsiveness to a constantly shifting environment. Adaptability, not efficiency, must become our central competency.” – General Stanley McChrystal in “Team of Teams”
“We became what we called “a team of teams”: a large command that captured at scale the traits of agility normally limited to small teams.” – General Stanley McChrystal in “Team of Teams”
“Specifically, we restructured our force from the ground up on principles of extremely transparent information sharing (what we call “shared consciousness”) and decentralized decision-making authority (“empowered execution”)” – General Stanley McChrystal in “Team of Teams”

“What had been logical became dumb, and all it took was changing the context.” – James Corey in “Abaddon's Gate”
Coordinate cross-functionally but work independently - take responsibility. Work with details, but understand the context. Act now—think long-term. Build know-how through continuous learning. Stimulate commitment through involvement. – Scania leadership principles
“Lean development is a careful elaboration of a single idea—learn from reality. And learning from reality has the great advantage of enabling you to live in a rational universe.” – Allen Ward in “Lean Product and Process Development”.
“Succinctly, “grownups” learn to value “power-to” over “power-over.” – Allen Ward in “Lean Product and Process Development” on role of management
“Put key information in the physical environment where it is available at a glance and people are reminded of it in appropriate places.” – Allen Ward in “Lean Product and Process Development” on why we seem to want to keep information hidden and pass it through workflows.
“Keep in mind that you cannot load the organization to 100% capacity. You need to figure in a buffer, normally in the 15–20% range unless you only do fairly routine development work.” – Allen Ward in “Lean Product and Process Development”. And related:
- “Adding a person who is unfamiliar with the project usually slows it down further while they get up to speed. So, lean companies use supervisors as the critical flexible resource. Supervisors are already familiar with each project their sections support. They are experienced developers. They can quickly step in to maintain the momentum and the flow. This critical role of lean supervisors and managers is almost unknown in conventional companies.”
“The answer is simple: establish a cadence. Start projects at standard intervals, and finish them at standard project lengths, so that the entire development organization is marching to the beat of the same drummer” – Allen Ward in “Lean Product and Process Development”.
“A plan that is more than one page is much too long to be understood and followed.” – Allen Ward in “Lean Product and Process Development”.
“Conventional project management attempts to answer these questions by defining a detailed plan and trying to stick to it. Instead of learning to surf, conventional organizations try to control the waves! This almost never works.” – Allen Ward in “Lean Product and Process Development”.
“Remain “off-line” from product development. Don’t allow research or advanced development to select a concept for product development. Product Development may use any of the data and ideas created, but research/ advanced development should always start with complete freedom to do whatever makes sense. Research or advanced development concepts are unproven because they have not been produced in volume or used by customers. Development teams must search many concepts to be confident of success.” – Allen Ward in “Lean Product and Process Development”.
“Every specification is a trade-off between what really is wanted and what the state of the art allows. At the beginning of the project, only the old state of the art is known.” – Allen Ward in “Lean Product and Process Development”.
“Your basic negotiating ploy is simple: “Given support A, I can do X. Given support B, I think I can only do Y. X makes 50% more money for the company.” – Allen Ward in “Lean Product and Process Development”.
“You can’t just ask customers what they want and then try to give that to them. By the time you get it built, they’ll want something new.” – Steve Jobs
“The project leader must be both an entrepreneur and a system designer.” – Allen Ward in “Lean Product and Process Development”. And related:
- “In contrast, large conventional companies often make an irrecoverable mistake: They aim project leaders at administering the project rather than designing the system. Whatever the organizational structure, the ESDs (engineering system designers) need to focus the bulk of their time and effort on creating new system knowledge for effective future value streams. It is precisely the ability to formulate a compelling but realistic vision and make good trade-offs that enables profitable products. 'Product visions' are just hot air unless they are inspired by engineering imagination and infused with engineering judgment.”

“Why doesn’t every company use ESDs effectively? Because ESDs drive bureaucrats nuts, for two main reasons: 1. ESDs trust their own judgment and love their own vision, and when these get off track, they can be disastrous. 2. ESDs won’t play the game; good bureaucrats do. Bureaucrats are properly deferential to authority. They mingle well at parties.”
“Committees never do anything completely wrong, but they never do anything brilliant either.” – Kelly Johnson
“We should buy both design and make whenever we can. Why? Because it reduces the amount that we have to learn.” – Allen Ward in “Lean Product and Process Development”.
“As a pilot instructor would say, 'Relax and level the wings.' In other words, stop doing those things that make the situation worse and take measured corrective action; which is, in this case, value-stream alignment.” – Allen Ward in “Lean Product and Process Development”.
“Quality, timing, and design integration are strongly interactive properties, not isolated ones. Interactive properties have more effect on profit than isolated ones.” – Allen Ward in “Lean Product and Process Development”. And related:
“A good system designer will rarely choose the supplier with the lowest price, even if cost is important to the product. Price is an isolated property of the part. It has little effect on how the part works in the system as a whole. Suppose a part involves 10% of the cost of the product—increasing the part cost by 10% will increase the product cost by only 1%. The effect is isolated. Conversely, if the part fails in service, the whole product fails. If the supplier delivers the part late, the whole product is late. If the part design doesn’t fit well into the system design, the customer is likely to be dissatisfied with the whole system.”
“In summary, these wastes are: 1. Scatter: management actions such as reorganization and workload variation that make knowledge hard to get to the right place; barriers to communication, such as the use of multiple forms (paper or electronic) to carry information through channels; and poor tools, which most often generate information that would have been useful in preventing a past problem but do not prevent future problems efficiently. 2. Hand-off: the most critical waste, occurring whenever a company separates responsibility, knowledge, action, and feedback; useless information, usually generated to provide management with the illusion of control; and waiting, the practice of putting learning into batches so that knowledge flows in only one direction. 3. Wishful Thinking: making decisions without data; testing to specifications, which leaves the product vulnerable to problems too infrequent for the specifications to catch; and discarded knowledge, which is the failure to put everything learned during a project into usable form.” – Allen Ward in “Lean Product and Process Development”.
“Testing’s job is to break the product, record how it breaks, and advise design engineering on how to make it harder to break.” – Allen Ward in “Lean Product and Process Development”.
“The natural intuition is that looking at one alternative is cheaper, easier, and faster than looking at multiple alternatives. This intuition is usually wrong, because looking at a lot of alternatives early is usually cheaper than looking at a few alternatives later; and choosing the one alternative, if we must do it with little knowledge, is simply wishful thinking.” – Allen Ward in “Lean Product and Process Development”.
“My job is to keep people from making decisions too quickly.” – Senior manager at Toyota
“It’s hard to find a development upstream process that has to finish before a downstream process can start. This is a major difference between development and manufacturing, and between development and construction (the environment for which PERT was designed).” – Allen Ward in “Lean Product and Process Development”. And related:
“Sequencing creates a batch process in which all the decisions and learning of a particular kind happen at once. This: 1) Slows the process because people wait longer than they need to before starting. 2) Creates one-way rather than multiway information flows; the upstream processes don’t get enough input from the downstream processes. 3) Gives the upstream developers more power than the downstream, creating quality problems. 4) Causes large variations in workload, which in turn causes scatter waste.”
“What is the most fundamental waste in conventional companies? Hand-off … A hand-off occurs whenever we separate knowledge, responsibility, action, and feedback. Hand-off is a disaster because it results in decisions being made by people who do not have enough knowledge to make them well or the opportunity to make them happen. Similar to the waste of overproduction on the plant floor, hand-off tends to produce many other kinds of development waste” – Allen Ward in “Lean Product and Process Development”.
“Hand-off creates finger-pointing—the conventional management salute.” – Allen Ward in “Lean Product and Process Development”.
“The most important wastes in development are wastes of knowledge.” – Allen Ward in “Lean Product and Process Development”.
“There are three primary categories of knowledge wastes: scatter, hand-off, and wishful thinking” – Allen Ward in “Lean Product and Process Development”.
“Scatter often is a death spiral, a feedback loop that makes things worse and worse. As things “fall through the cracks” because of disorganization, developers spend more time “fighting fires,” responding to demands for information by others, and looking for information and harassing other developers to try to get action. Everything becomes a crisis” – Allen Ward in “Lean Product and Process Development”.
“These responses to scatter create more scatter. The result: more time spent creating waste and less time creating value.” – Allen Ward in “Lean Product and Process Development”.
“Going faster improves profitability in several ways: 1) Saving time saves money. The size of a team is determined mostly by the range of expertise required. Getting done faster frees resources. 2) In markets with low switching costs for the customer to change from one supplier to another, going faster means you get your share of the market sooner. You probably keep it just as long, so you add some months or years of profit to your ROI. 3) In markets with high switching costs, getting to market first could mean you get most of the market—and you get to keep it. 4) If you are selling to industrial customers that are in a hurry themselves, the promise of speed may be enough by itself to radically improve market share and ROI. 5) Above all, of course, going faster means learning faster. If you learn 20% faster than your competitors, 30 projects later you will be 60% ahead—a tremendous advantage.” – Allen Ward in “Lean Product and Process Development”
“Estimate value-creating time for developers. Ask your developers (anonymously, at least at first) what fraction of their time is spent creating value—creating usable new knowledge or manufacturing hardware. Calculate how much you could increase your throughput by increasing your fraction of value-adding creating time. Publicize.” – Allen Ward in “Lean Product and Process Development”
“Almost all defective projects result from not having the right knowledge in the right place at the right time. Therefore, usable knowledge is the basic value created during development. Usable development knowledge prevents defects, excites customers, and creates profitable operational value streams.” – Allen Ward in “Lean Product and Process Development”.
“Usable knowledge is created by three basic kinds of learning: 1. Integration learning includes learning about customers, suppliers, partners, the physical environment in which the product will be used, etc. It helps us understand how to integrate our designs with the needs of others—most importantly, our customers. 2. Innovation learning creates new possible solutions. 3. Feasibility learning enables better decisions among the possible new solutions, avoiding cost and quality problems, or project overruns.” – Allen Ward in “Lean Product and Process Development”.
“Keep the ROI model simple enough for developers to understand and use in daily work.” – Allen Ward in “Lean Product and Process Development”
“Improving the system to prevent defects does NOT mean adding more tests, analysis, signatures, gates, or controls to the system. These things make developers work harder, in an effort to prevent a particular problem from reoccurring. But the basic problem is that every developer I know already is working too hard, so things “fall through the cracks.” Improving the system means making things easier for developers, not harder.” – Allen Ward in “Lean Product and Process Development”
“Use project defect rate to spur change Determine your project defect rate. To do this, plot the distribution of ROIs for recent projects, color coding for defective and completely successful projects. Compute how much more money you would make if all projects returned the maximum ROI. Publicize this in internal media, or post it in halls; use it to agitate for lean development.” – Allen Ward in “Lean Product and Process Development”.
“Unless you keep spreading the virus, the immune system of the organization will reject it.“ – Allen Ward in “Lean Product and Process Development”
“While we acknowledge emergence in design and system development, a little planning can avoid much waste.” – James Coplien
“It is said that a wise person learns from his mistakes. A wiser one learns from others' mistakes. The wisest person of all learns from others' successes.” – John C Maxwell
“Every dependency you can remove from your delivery stream doubles your chances of delivering on time.” – Troy Magennis.
“For high utilization systems we need to track system level impediments to the flow.” – Troy Magennis
“Its impossible to forecast a system under high utilization” – Troy Magennis. High utilization means non-linear effects become part of the system which means you cannot estimate.
“A symptom of over-utilization in a system is high batch size” – Troy Magennis
“If the system is so over-utlitized then you might as well send a truck through the system as a car, as you'll end up with more at the end.” – Troy Magennis
“A bad system will keep a good developer down.” - Troy Magennis
“Note - these are just ideas / approaches. If the approach does not suite your context, believe the context, and adjust the approach” – Hans Samios
“Scope doesn't creep. Understanding grows.” – Jeff Patton
“Caution! Support organizations should support, not control. All too often, they optimize their work and make decisions that should be made by people who work on products. By taking this responsibility away from Scrum teams, the support mutates into a burden. Make sure to focus on support” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“Part-time people equate to part-time commitment. Part-time commitment leads to team failure” – Jensen
“The sooner you get behind schedule, the more time you have to make it up.” – Anonymous
“2B | ¬2B, that is the question” – Hamlet, early hexadecimal programmer
“Plus, research [Katz82] shows that long-lived stable R&D teams are correlated with higher productivity than temporary project groups of people drawn from a resource pool” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“The most powerful form of 'queue management' is to utterly eradicate a queue by changing the system.” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“Humans are probably more sensitive to time variation than to scope variation — 'It was late' is remembered more strongly than, 'It had less than I wanted.'” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“Time-boxing limits scope creep, limits gold-plating, and increases focus — one of the Scrum values.” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“Simply, cadence at work improves predictability, planning, and coordinating” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“Focus on large-scale test automation — to learn about defects and behavior. The setup costs are non-trivial (if you are currently doing manual testing) but the re-execution costs are almost zero.” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“Self-directed work — This is a theme found in effective-team research. Notice that visual management supports self-directed work because people can easily see what is going on, to coordinate.” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“This is one purpose of the Scrum Product Backlog. It acts as a tool for leveling or smoothing the introduction of work to feature teams. A small buffer of high-quality inventory created to support level pull is another example of useful temporarily necessary waste” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“It is interesting to note that people’s models of causation are influenced by the timeliness (delay) and quality of feedback in the system.” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
““Common sense” is not so reliable when trying to understanding nonlinear systems—such as large-scale product development.” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”

“Weinberg-Brooks’ Law: More software projects have gone awry from management’s taking action based on incorrect system models than for all other causes combined. Causation Fallacy: Every effect has a cause … and we can tell which is which.” – Gerry Weinberg
“Consequently, this book suggests that one cornerstone for large-scale Scrum and agile development is people who learn and apply various thinking tools, including (but not limited to) systems thinking, mental-model awareness, lean thinking, queueing theory, and recognition of false dichotomies.” – Craig Larman, Bas Vodde from “Scaling Lean and Agile Development”
“Whether you believe that you can do a thing or not, you are right.” – Henry Ford
“The Wright brothers achieved the dream of flight through an organized, disciplined process of diligently orchestrated learning cycles. Each learning cycle was designed to create knowledge, which they captured on limit and trade-off curves. They had set out to undertake a study of flight and make a contribution in advancing the knowledge of powered flight. The process they employed was so successful that the result was the invention of the airplane. Clearly, there is much to be learned from their process.” – Dantar P. Oosterwal in "The Lean Machine"
“It's what you learn after you know it all that counts.” – John Wooden
“To unilaterally optimize the overall flow of projects across the entire development portfolio, a product development cadence must be established.” – Dantar P. Oosterwal in "The Lean Machine"

“Cadence is even more critical in the product development environment, where flow is not inherently observable” – Dantar P. Oosterwal in "The Lean Machine"
“Cadence is the metronome to pace work in all areas of business outside standard, routine production.” – Dantar P. Oosterwal in "The Lean Machine"
“A firefighting organization requires extraordinary people to achieve ordinary results. In an exceptional organization, ordinary people achieve extraordinary results routinely.” – Dantar P. Oosterwal in "The Lean Machine"
“In contrast to work standards, standardized work is determined collectively by the group closest to the work.” – Dantar P. Oosterwal in "The Lean Machine"

“Someone who achieves a high level of personal mastery lives in a continual learning mode with no end state. They never “arrive.” – Dantar P. Oosterwal in “The Lean Machine”
“The five disciplines of a learning organization are: 1. Systems thinking. 2. Personal mastery. 3. Mental models. 4. Building shared vision. 5. Collective team learning.” – Dantar P. Oosterwal in "The Lean Machine"
“Complex systems exhibit several kinds of telltale behaviour. I will describe some of these behaviours briefly here; they will be examined in more detail in later chapters. • self-organization into patterns, as occurs with flocks of birds or schools of fish • chaotic behaviour where small changes in initial conditions (‘the flapping of a butterfly’s wings in Argentina’) produce large later changes (‘a hurricane in the Caribbean’) • ‘fat-tailed’ behaviour, where rare events (e.g. mass extinctions and market crashes) occur much more often than would be predicted by a normal (bell-curve) distribution • adaptive interaction, where interacting agents (as in markets or the Prisoner’s Dilemma) modify their strategies in diverse ways as experience accumulates. In addition, as already mentioned, emergent behaviour is an essential requirement for calling a system ‘complex’.” – John Holland from “A Very Short Introduction to Complexity”
“Restated for complex systems: emergent properties at any level must be consistent with interactions specified at the lower level(s).” – John Holland from “A Very Short Introduction to Complexity”
“Each of these complex systems exhibits a distinctive property called emergence, roughly described by the common phrase ‘the action of the whole is more than the sum of the actions of the parts” – John Holland from “A Very Short Introduction to Complexity”
“The point here is that most reasonable people don’t have to get their way in a discussion. They just need to be heard, and to know that their input was considered and responded to.” – Patrick Lencioni from “The Five Dysfunctions of a Team”
“Politics is when people choose their words and actions based on how they want others to react rather than based on what they really think.” – Patrick Lencioni from “The Five Dysfunctions of a Team”
“I want to assure you that there is only one reason that we are here at this off-site, and at the company: to achieve results. This, in my opinion, is the only true measure of a team” – Patrick Lencioni from “The Five Dysfunctions of a Team”

“Understanding economics requires an understanding of the interaction amongst multiple variables.” – Don Reinertsen “Principles of Product Development Flow”
“Left to themselves, components (of a system) become selfish, independent profit centers and thus destroy the system.” – W. Edwards Deming
“All we are doing is looking at the timeline, from when the customer gives us an order to when we collect cash And we are reducing the timeline by reducing the non-value added wastes.” - Taiichi Ohno
“Development managers today face an important trade-off between steady state of performance and the system's ability to accommodate unanticipated changes in resource requirements without descending into the firefighting cycle … Development managers and company leadership with a desire to avoid firefighting must rethink their approach to managing multi-project development portfolios.” – Dantar P. Oosterwal in "The Lean Machine"
“People who operate within the development system are rarely directly to blame. Individual mistakes happen. However, consistent lack of performance must be attributed to systemic issues. To improve the development system, it must first be recognized that a bad system will always undermine even the best efforts of good people. Bad systems beat good people every time!” – Dantar P. Oosterwal in "The Lean Machine"
“There was in fact no correlation between exiting phase gates on time and project success. The data suggested the inverse was true.” – Dantar P. Oosterwal in "The Lean Machine"

“Integration points control product development.” – Dantar P. Oosterwal in "The Lean Machine"
“Passion is inversely proportional to the amount of real information available” – “Benford's Law of Controversy”, Gregory Benford, 1980
“The most important and visible outcropping of the action bias in the excellent companies is their willingness to try things out, to experiment. There is absolutely no magic in the experiment … But our experience has been that most big institutions have forgotten how to test and learn. They seem to prefer analysis and debate to trying something out, and they are paralyzed by fear of failure, however small.” – Tom Peters and Robert Waterman, In Search of Excellence (Peters & Waterman, 1982)
“Cease dependence on mass inspection to achieve quality. Improve process and build quality into the product in the first place.” – Deming
“A project plan is like a lettuce. On the day you buy it, it looks firm and crispy; a week later its a bit wilty around the edges, and after a month its unrecognizable.” – Martin Fowler quoting a project manager.

“In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day.” – Carl Sagan

“Motivation – nonsense. All that people need to know is why their work is important.” – W. Edwards Deming
“The idea of a merit rating is alluring. The sound of the words captivates the imagination: pay for what you get; get what you pay for; motivate people to do their best, for their own good. The effect is exactly the opposite of what the words promise. Everyone propels himself forward, or tries to, for his own good, on his own life preserver. The organization is the loser. The merit rating rewards people that conform to the system. It does not reward attempts to improve the system. Don’t rock the boat.” – W. Edwards Deming, “The Merit System: The Annual Appraisal: Destroyer of People,” 1986.

“Worried that TDD will slow down your programmers? Don't. They probably need slowing down.” – J. B. Rainsberger
“In particular I always argue that high-level tests are there as a second line of test defense. If you get a failure in a high level test, not just do you have a bug in your functional code, you also have a missing unit test. Thus whenever you fix a failing end–to–end test, you should be adding unit tests too.” – Martin Fowler
“It's not the practices; its the culture that makes you want to use these practices.” Boeing Exec to Joe Justice.

“The surest way to mismanage a project and jeopardize a product is to put too much emphasis on the schedule as it demoralizes the team and drives them to make stupid decisions despite their better judgments.” – Steve Maguire “Debugging the Development Process”
“While working with these teams, I discovered that they were all making the same fundamental errors and they were perpetually repeating those errors … In every group I worked with, I found the project leads were spending nearly all their time writing code and almost none of their time thinking about the project. The leads didn't spend time trying to keep schedules on track, they didn't look for foreseeable problems so they could circumvent them, they didn't work to protect other team members from unnecessary work, they didn't pay particular attention to training other team members, they didn't set detailed project goals or create effective attack plans. The leads were spending too much time working when they should have been thinking.” – in preface by Steve Maguire “Debugging the Development Process”.

“Computers are useless. They can only give you answers.” – Pablo Picasso
“It is useful to do detail planning, but you always want to use it with a short time horizon because detailed planning is very perishable. You do not want to hold a large inventory of detailed planning because you are throwing money away when you do that.” – Don Reinersten.

“Clean code is simple and direct. Clean code reads like well–written prose. Clean code never obscures the designer’s intent but rather is full of crisp abstractions and straightforward lines of control.” Grady Booch
“I could list all of the qualities that I notice in clean code, but there is one overarching quality that leads to all of them. Clean code always looks like it was written by someone who cares. There is nothing obvious that you can do to make it better. All of those things were thought about by the code’s author, and if you try to imagine improvements, you’re led back to where you are, sitting in appreciation of the code someone left for you—code left by someone who cares deeply about the craft.” – Michael Feathers
“You know you are working on clean code when each routine you read turns out to be pretty much what you expected. You can call it beautiful code when the code also makes it look like the language was made for the problem.” Ward Cunningham
“Clean code is not written by following a set of rules. You don’t become a software craftsman by learning a list of heuristics. Professionalism and craftsmanship come from values that drive disciplines.” – Robert “Uncle Bob” Martin

“Your project, the whole project, has a binary deliverable. On scheduled completion day, the project has either delivered a system that is accepted by the user, or it hasn’t. Everyone knows the result on that day. The object of building a project model is to divide the project into component pieces, each of which has this same characteristic: Each activity must be defined by a deliverable with objective completion criteria. The deliverables are demonstrably done or not done.” – Tom Demarco – Controlling Software Projects (1982)

“Poor management can increase software cost more rapidly than any other factor.” – Barry Boehm, Software Engineering Economics, 1981
“Self-organization does not mean that workers instead of managers engineer an organization design. It does not mean letting people do whatever they want to do. It means management commits to guiding the evolution of behaviors that emerge from the interactions of independent agents instead of specifying in advance what effective behavior is.” – Philip Anderson, The Biology of Business
“Self-organizing is about the team determining how they will respond to their environment (and managers / leaders can influence that environment.” – Mike Cohn

“Plans based on average assumptions are wrong on average!” – Sam Savage from “The Flaw of Averages”
“This leads us to the odd conclusion that strict control is something that matters a lot on relatively useless projects and much less on useful projects. It suggests that the more you focus on control, the more likely you’re working on a project that’s striving to deliver something of relatively minor value.” – Tom DeMarco in “Software Engineering: Idea Whose Time Has Come And Gone”
“No matter how far down the wrong road you’ve gone, turn back.” – Turkish proverb
“Bubbles don't crash.” – Bertrand Meyer.

“Brooks's law is a principle in software development which says that “adding manpower to a late software project makes it later”. – Fred Brooks in his 1975 book The Mythical Man–Month.
“Here is Edward Bear, coming downstairs now, bump, bump, bump, on the back of his head. It is, as far as he knows, the only way of coming downstairs, but sometimes he feels that there really is another way, if only he could stop bumping for a moment and think of it. And then he feels that perhaps there isn't.” – A. A. Milne

The fundamental reason for partnerships is synergy, people – and companies – can achieve better results through cooperation than they can achieve individually.” – Mary Poppendieck from “Implementing Lean Software Development”
“A world class 'varsity eight' (plus coxswain) can cover 2000 meters over the water in about 5.5 minutes. However, a single sculler can at best row the same distance in about 7 minutes. The difference is synergy, and if rowing faster were a matter of survival, the cooperators would be the fittest.” – Peter A Corning, from “The Synergism Hypothesis: In the Concept of Synergy and Its Role in the Evolution of Complex Systems”.
“It’s hard for Americans to understand the idea that a business organization cannot improve its long term financial results by working to improve its financial results. But the only way to ensure satisfactory and stable long term financial results is to work on improving the system from which those results emerge.” – H. Thomas Johnson, winner of the Deming Medal of honor.
“Purely people factors predict project trajectories quite well, overriding choice of process or technology. I found no interesting correlation in the projects that I studied among processes, language, or tools and project success. I found success and failures with all sorts of processes, languages and tools. A well–functioning team of adequate people will complete a project almost regardless of the process or technology they are asked to use (although the process and technology might help or hinder them along the way).” – Alistair Cockburn, “Agile Software Development”, 2002

“Just because Scrum doesn’t say anything about breakfast doesn’t mean you have to go hungry!” – Pete Deemer & Gabrielle Benefield Yahoo, 2006
“A well functioning Scrum will deliver highest business value features first and avoid building features that will never be used by the customer. Since industry data shows over half of the software features developed are never used, development can be completed in half the time by avoiding waste, or unnecessary work.” – Jeff Sutherland 2006 – “The Nuts and Bolts of Scrum”
“In most companies, development is slowed down by impediments identified during the daily meetings or planning and review meetings. When these impediments are prioritized and systematically removed, further increases in productivity and quality are the result. Well run Scrums achieve the Toyota effect – four times industry average productivity and 12 times better quality.” – Jeff Sutherland 2006 – “The Nuts and Bolts of Scrum”
“I believe that the prevailing system of management is, at its core, dedicated to mediocrity, It forces people to work harder and harder to compensate for failing to tap the spirit and collective intelligence that characterizes working together at its best.” – Peter Senge, MIT on traditional command and control approaches to management.
“Any piece of software reflects the organizational structure that produced it.” – Conway's Law.

“A stronger 'definition of done' will always increase velocity and improve quality”. Jeff Sutherland at Agile 2008: Jeff Sutherland: Reaching Hyper–Productivity with Outsourced Development Teams
“When it comes to code it never pays to rush.” – Marick’s law
“The task is then to refine the code base to better meet customer need. If that is not clear, the programmers should not write a line of code. Every line of code costs money to write and more money to support. It is better for developers to be surfing than writing code that won't be needed. If they write code that ultimately is not used, I will be paying for that code for the life of the system, which is typically longer than my professional life. If they went surfing, they would have fun, and I would have a less expensive system and fewer headaches to maintain.” – Jeff Sutherland, quoted from object–technology@yahoogroups.com Message 121
“Predictable outcomes are one of the key expectations that the marketplace imposes on companies … Unfortunately, software development has a notorious reputation for being unpredictable, so there is great pressure to make it more predictable. The paradox is that in our zeal to improve the productivity of software development, we have institutionalized practices that have the opposite effect.” – Mary and Tom Poppendieck, from “Implementing Lean Software Development” (pg 31–32).
“Everybody has a plan until they get punched in the mouth.” - Mike Tyson
“We can't solve problems by using the same kind of thinking we used when we created them.” – Einstein
“We never have time to do it right; we always have time to do it twice.” – Unknown

“A change in requirement late in the development cycle is a competitive advantage provided you can act on it.” – Mary Poppendieck
“Design, development, test and documentation are activities NOT people.” – Bob Schatz during sprint planning training.
“If you already know the project is going to fail, then a lot of traditional documentation in a project is about figuring out ‘who to blame'” – Bob Schatz during sprint planning training
“User stories are not use cases” – Mike Cohn
“Scrum is just the result of software developers going through a midlife crisis” – Unknown
“Waterfall is a software development process which works as if it were designed for the convenience of lawyers” – Unknown

”… if a build is not breaking then it is doubtful the team is pushing itself hard enough and concerns should be raised” – Troy Magennis on the “continuous build / integration” process
“Trying to improve software quality by increasing the amount of testing is like trying to lose weight by weighing yourself more often. … If you want to lose weight, don't buy a new scale; change your diet. If you want to improve your software, don't test more; develop better.” – Steve C McConnell, “Code Complete: A Practical Handbook of Software Construction”, 1993
“It is typical to adopt the defined (theoretical) modeling approach when the underlying mechanisms by which a process operates are reasonably well understood. When the process is too complicated for the defined approach, the empirical approach is the appropriate choice.” – B.A. Ogunnaike and W.H. Ray (Process Dynamics, Modeling and Control)
“Of the organizations that are attempting to implement Scrum, probably 30–35% will successfully implement it. And that's because of this core problem. Most organizations don't want to be faced with what they don't want to see. And this puts it up there and says 'are you going to do something about it, or not'?” – Scrum et al by Ken Schwaber talking at Google.
“One of the industry statistics is that over 65% of the functionality that is delivered and then has to be maintained and sustained is rarely or never used” – Scrum et al by Ken Schwaber talking at Google. Quote refers to a study by the Standish Group.
“Scrum is a “lean” approach to software development.” – Jeff Sutherland 2006
