Knowing the business priorities and implications of the stuff you do is essential for lean and agile development. Without that knowledge economic decisions and re-planning cannot be delegated into the organization. In spite of that there are very few organizations where development teams can base their decisions on business priorities. For this Cost of Delay is the most important economic factor in development and basis for prioritization (D. Reinertsen, The Principles of Product Development Flow). Ranking and prioritization should be based solely on economics and use a Weighted Shortest Job First (WSJF) algorithm. Scaled Agile Framework takes on and simplifies this WSJF.
In this talk I will present the principles behind WSJF prioritization, the simplification suggested in SAFe and how it can be applied practically outside of a SAFe context. I will also show a suggestion for even simpler WSJF ranking based on relative comparison only, which is easy to keep up to date in the daily work. As I see it, this simplification leads to slightly less accurate rankings, but will be kept up to date and performed more often, which should lead to better overall prioritization results. A discussion about the pros and cons will conclude the session.
