 When you move to agile, there is a tendency to say "we'll do this agile thing with developers, but we will keep our traditional phase gate approach to approving budgets". After all, to decide whether we should spend the money "we will need to know how much it will cost and that means we will have to do some level of analysis before making any decisions." When you move to agile, there is a tendency to say "we'll do this agile thing with developers, but we will keep our traditional phase gate approach to approving budgets".

-Take a look at the diagram. This is the same diagram in as before for a fictitious project. On it we see the the value delivered by an agile project doing highest value first. Compare this with a project where we do up front analysis before we start working any value delivery. How much time do you spend on detailed requirements? Industry statistics indicate that this could be anywhere from 30-50% of the total project time. What about financial analysis and all the details required to get through a "start project" phase gate? How much does that add the total project time? +Take a look at the diagram. This is the same diagram in as  [[how_does_the_agile_approach_allow_us_to_deliver_early|before]] for a fictitious project.

 It doesn't really matter. No matter how you look at it in the time an agile project could be delivering a large percentage (40%? 50%? 60%) of the expected value for the project, the traditional approach has still only completed analysis, leaving all the risk remaining in the project. And remember, not only do we have no value delivered, but the additional analysis has also increased the risk associated with our plan. It doesn't really matter.

-This is not to say that we don't do approval for work when we take on an agile approach. Of course we do. We just minimize the analysis based on what is realistically possible, then start working anything that gets through while using [[blog:how_can_we_understand_the_real_value_of_fast_feedback_and_deciding_late|fast feedback]] to adjust the course we are heading based on latest information. In particular, we end up making more smaller bets based on current information, perhaps releasing money every quarter instead of developing a "committed plan" for years in advance.+This is not to say that we don't do approval for work when we take on an agile approach.

 And yes, I understand, this is a change in the thinking. It will probably mean you will have to get the finance people, the business people, and the marketing folks involved in the change in thinking process. But given the economic benefits that could result, isn't the change worth the effort? And yes, I understand, this is a change in the thinking.
