Try this …
- Get proposed feature list
- Assign “business value points” using Fibonacci – just relative ranking – use Planning Poker – this is a team exercise with PO’s, Architects, other SME’s. Complete this step for entire feature list before moving on to step 3.
- Assign “cost points” (or “size points”, or “Feature Points”) – Again, relative sizing using a Fibonacci scale.
- Rank = Value/Cost. (This is WSJF slightly simplified). Sets priorities for release planning.
