Discuss ISQI CTFL_Syll_4.0 Exam Topic 3 Question 40

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

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.

Just a reminder, the cards are 1, 2, 3, 5, 8, 13, 21.

I think we should go with option B for sure.

Azzie 10 months ago

Seems like a huge gap in estimates!

Ricarda 10 months ago

Wait, how can Memb4 think it's 21? That’s wild!

James 11 months ago

Totally agree with D, we need to discuss those extremes.

Larae 11 months ago

I think it's crucial to hear from Memb4 and Memb6 about their estimates. It could help clarify the situation before we estimate again, which aligns with option D.

Heike 11 months ago

I feel like using the three-point estimation technique is something we covered, but I can't recall if we should apply it here. Option A seems a bit off to me.

Geraldine 11 months ago

I'm not entirely sure, but I think we might have practiced something similar where we just kept estimating until everyone agreed. That sounds like option B, right?

Geoffrey 11 months ago

I remember we discussed that when there's a wide range of estimates, it's important to have a conversation to understand the reasoning behind them. So, I think option D makes sense.

Bette 12 months ago

Hmm, I'm leaning towards trying another round of estimation. Getting everyone on the same page seems important here.

Lera 12 months ago

I'm pretty confident my estimate of 21 is accurate, but I'm open to hearing the others' perspectives. We need to work through this as a team.

Wilda 12 months ago

I think the key is to get everyone to explain their reasoning, like the question suggests. That should help us converge on a shared understanding.

Selene 1 year ago

I'm a bit confused by the different estimates. I'm not sure if we should go with the average or try another round of estimation.

Ling 1 year ago

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.
