Agile Project Management Estimation Techniques 3

Question 1

In T-shirt sizing, what do the sizes (S, M, L, XL) primarily help teams do early on?

Accepted Answer

Estimate quickly at a coarse, relative level

Answer

T-shirt sizing gives a fast, rough relative grouping useful before detailed estimation.

Question 2

Affinity estimation is most useful when a team needs to size what?

Accepted Answer

A large number of backlog items quickly

Answer

Affinity estimation groups many items by relative size rapidly, ideal for large backlogs.

Question 3

What is the 'bucket system' estimation technique designed to handle?

Accepted Answer

Estimating many items by placing them into predefined size buckets

Answer

The bucket system speeds up large-scale estimation by sorting items into fixed-value buckets.

Question 4

Why is relative estimation often more accurate than absolute time estimation for humans?

Accepted Answer

People compare sizes better than they predict exact durations

Answer

Humans are better at judging that one item is bigger than another than at predicting exact time.

Question 5

During affinity estimation, what is typically done first?

Accepted Answer

Silently arrange stories from smallest to largest

Answer

Teams often begin by silently ordering stories by relative size to surface a quick baseline.
