What is the main idea behind '#NoEstimates' approaches?
Answer: Forecast using counts of completed items rather than point estimates
#NoEstimates favors forecasting from throughput (item counts) instead of detailed point estimation.
In a three-point (PERT) estimate, which values are combined?
Answer: Optimistic, most likely, and pessimistic
PERT blends optimistic, most likely, and pessimistic estimates to account for uncertainty.
Why does estimation uncertainty decrease as a project progresses?
Answer: The team learns more, narrowing the cone of uncertainty
The 'cone of uncertainty' narrows as knowledge increases and unknowns are resolved.
What is the benefit of re-estimating a backlog item that has grown in understood scope?
Answer: It keeps forecasts realistic as knowledge changes
Updating estimates as understanding improves keeps planning aligned with reality.
How can throughput (items completed per sprint) be used for forecasting?
Answer: Divide remaining item count by average throughput
Forecasting by throughput estimates completion time from how many items finish each sprint on average.
What is a common cause of chronic underestimation in teams?
Answer: Ignoring non-coding work like testing and integration
Forgetting hidden work such as testing, reviews, and integration leads to consistently low estimates.
Why is it recommended to estimate as a whole team rather than individually?
Answer: Diverse perspectives surface risks and shared understanding
Team estimation pools knowledge, exposes hidden complexity, and builds shared commitment.
