CAPM Practice: Explain the components of an adaptive plan

Traditional expert estimation suffers from anchoring bias: when one expert states an estimate, others tend to align with it even if they privately disagree. Planning poker prevents this by having all estimators reveal their estimates simultaneously, before discussion. Outlier estimators (highest and lowest) then explain their reasoning, surfacing assumptions and domain knowledge that improve the collective estimate.

**Why not A:** Planning poker is not necessarily faster than expert estimation — it often takes more time due to discussion rounds after revealing estimates. Its advantage is not speed but accuracy and inclusiveness, as it prevents anchoring bias and surfaces diverse perspectives.

**Why not C:** This reverses the typical usage. Planning poker commonly uses relative units like story points, while traditional expert estimation often uses hours or days. Planning poker's strength is in relative comparison, not hour-based estimation.

**Why not D:** Planning poker is effective with any team size — it is not limited to large teams. It is commonly used with standard Scrum teams of 5-9 people. The key benefit is simultaneous estimation regardless of team size, not that it requires many estimators.
