BCS Exam CTFL4 Topic 1 Question 19 Discussion

Actual exam question for BCS's CTFL4 exam

Question #: 19
Topic #: 1

Consider an estimation session in which a six-member Agile team (Memb1..... 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:

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 proceeding to another estimation round

Show Suggested Answer

Suggested Answer: D

In Agile teams using the planning poker technique for estimating user stories, it is common practice to have further discussions and rounds of estimation if there is a significant discrepancy in the initial estimates. This helps in reaching a consensus and ensures that all team members understand the complexity and requirements of the user story. According to the ISTQB CTFL syllabus, planning poker involves discussions to clarify differences in estimates, especially when there is a wide range of values selected. By having Memb6 and Memb4, who provided the most pessimistic and optimistic estimates, explain their reasoning, it fosters a deeper understanding and encourages the team to converge towards a more accurate and agreed-upon estimate.

I agree with Pamela. It's crucial to have a discussion and gain insights from Memb6 and Memb4 before moving forward.

Totally agree. We need to understand each other's perspectives before settling on a final estimate. Discussing the reasoning behind the outliers is the way to go.

I think the team should keep going with the planning poker until we all agree on a number. Averaging the extremes doesn't seem right to me.

I think we should go with option D. It's important to understand the reasoning behind the extreme estimates.
