Question
Which answer best describes Wide Band Delphi (e. g. Planning Poker) estimating?
Options
- ATeam members provide story estimates individually and discuss their reasoning until a
- BTeam performance on prior projects is analyzed, and actual hours and durations are used to
- CTeam members apply relative sizing to each task, and story points are triangulated based on
- DTeam members assign a realistic and a pessimistic estimate to each story, and points are
Explanation
Wide Band Delphi (including Planning Poker) is a consensus-based estimating technique where team members independently select their estimates, reveal them simultaneously, and then discuss the reasoning behind differing estimates. This process repeats until the team converges on a shared estimate. The simultaneous reveal prevents anchoring bias. Option B describes analogous estimating. Option C partially describes relative sizing but not the Delphi discussion/consensus process. Option D describes a variation of three-point (PERT) estimating, not Delphi.
