How do you handle a project budget when moving from Waterfall to a Hybrid PM approach?

All answers to this question.

This is the "Agile-Finance Paradox." To bridge the gap, I suggest using "Range Estimating" rather than fixed numbers. We typically budget for the "Must-Have" features in the initial Waterfall phase and then set up a rolling wave budget for the Agile components. Every quarter, we present the value delivered to the finance team to justify the next block of funding. It changes the conversation from "how much will this cost" to "what value have we realized so far." It requires a lot of education for the accounting team, but it creates much more flexibility.

Does your finance department allow for a "contingency fund" specifically for the Agile iterations, or do they expect every dollar to be mapped to a specific feature?

• Jeffrey, they usually hate the word "contingency." We’ve had better luck calling it a "Research and Development Allocation." It sounds more intentional. The key is to map the Agile story points to a "cost per point" metric over time. Once you have a stable velocity, you can actually give Finance a very accurate forecast of what a specific budget will buy in terms of features.

We use CapEx for the initial build and OpEx for the iterative Agile improvements. Splitting the budget this way helps satisfy the traditional accounting requirements of the firm.

• Great strategy, Rebecca. Categorizing the work as CapEx/OpEx is a language that Finance understands well and it really simplifies the approval process for long-term projects.
