In T-shirt sizing, what do the sizes (S, M, L, XL) primarily help teams do early on?
Answer: Estimate quickly at a coarse, relative level
T-shirt sizing gives a fast, rough relative grouping useful before detailed estimation.
Affinity estimation is most useful when a team needs to size what?
Answer: A large number of backlog items quickly
Affinity estimation groups many items by relative size rapidly, ideal for large backlogs.
What is the 'bucket system' estimation technique designed to handle?
Answer: Estimating many items by placing them into predefined size buckets
The bucket system speeds up large-scale estimation by sorting items into fixed-value buckets.
Why is relative estimation often more accurate than absolute time estimation for humans?
Answer: People compare sizes better than they predict exact durations
Humans are better at judging that one item is bigger than another than at predicting exact time.
During affinity estimation, what is typically done first?
Answer: Silently arrange stories from smallest to largest
Teams often begin by silently ordering stories by relative size to surface a quick baseline.
What is a reference story (or baseline story) used for in relative estimation?
Answer: A known-size anchor to compare other stories against
A reference story provides a shared anchor point so the team estimates consistently.
A team using T-shirt sizes later wants to forecast velocity. What must they do?
Answer: Map sizes to a numeric scale like points
To forecast quantitatively, qualitative sizes are mapped to numeric point values.
