iSQI CTFL_Syll_4.0 Exam - Topic 3 Question 40 Discussion

Actual exam question for iSQI's CTFL_Syll_4.0 exam

Question #: 40
Topic #: 3

Consider an estimation session in which a six-member Agile team (Membl,..., Memb6) uses the planning poker technique to estimate a user story (in story points). The team members will use a set of cards with the following values: 1. 2, 3, 5, 8,13, 21. Below is the outcome of the first round of estimation for this session:

Membl = 3 Memb2 = 3 Memb3 = 3

Memb4 = 21 Memb5 = 3 Memb6 = 1

Which of the following answers best describes how the estimation session should proceed?

AThe final estimate of the user story in story points is determined by applying the three-point estimation technique with the following input values: most optimistic estimate = 1, most likely estimate = 3, and most pessimistic estimate = 21

BFurther estimation rounds should be performed until all team members will pick the card having the same value: this value will represent the final estimate of the user story in story points

CThe final estimate of the user story in story points is determined by calculating the average value between the most optimistic estimate of 21 story points (Memb4) and the most pessimistic estimate of 1 story point (Memb6)

DMemb6 and Memb4 which have produced the most pessimistic and the most optimistic estimates respectively, should explain the reasons of their choices to stimulate a discussion between all members before to proceed to another estimation round

Show Suggested Answer

Suggested Answer: D

Planning poker is a consensus-based estimation technique used in Agile. It involves team members selecting cards with their estimate for a user story, then discussing the differences in estimates.

Option A: Incorrect. While three-point estimation is valid, planning poker focuses on team consensus rather than individual estimation techniques.

Option B: Incorrect. The goal of planning poker is not to force unanimity but to reach a reasonable consensus.

Option C: Incorrect. Averaging estimates is not how planning poker works.

Option D: Correct. The members with the highest and lowest estimates discuss their reasoning to foster understanding and adjust estimates accordingly in subsequent rounds.

This one's tricky, but I think we need to keep discussing until we reach a consensus. The wide range of estimates suggests we're not all on the same page yet.
