BCS Exam CTFL4 Topic 3 Question 17 Discussion

Actual exam question for BCS's CTFL4 exam

Question #: 17
Topic #: 3

During iteration planning, a scrum team uses an estimation technique called planning poker to estimate the effort required to deliver a critical user story. In advance of the estimation session, the team agreed on some ground rules to limit the number of poker rounds and save time.

The team agreed on the following:

1. They will use the following progression for estimation: Extra-small, Small, Medium, Large, Extra-large, and Extra-extra-large.

2. If estimation values differ significantly, the highest score will be used for estimation purposes.

The result of the first round of planning poker:

Team Member Estimation

Business Large

Development Extra-extra-large

Testing Extra-extra-large

Which of the following options best represent the team's next actions?

AThe fact that all estimations are high indicate that the user story is not well understood or should be broken down into multiple smaller stories.

BThe pre-agreed rules state that the highest score should be used for estimation, resulting in the user story being categorised as Extra-extra-large.

CSince the business representative is likely to have the most informed view of the requirement, the user story is categorised as a Large.

Dthe team discusses the differences in the estimates and repeats the poker round until an agreemet is reached.

Show Suggested Answer

Suggested Answer: D

In a planning poker session, if there is a significant difference in the estimations, it indicates that there may be misunderstandings or different perspectives on the complexity of the user story. According to the agile principles, the team should discuss these differences to reach a common understanding. The goal is to ensure that all team members have a shared understanding of the user story's scope and complexity before finalizing the estimate.

Ah, the joys of planning poker. Where the numbers are made up and the points don't really matter!

The business rep's view is important, but the whole team should be involved in the estimation process. I'd go with option D and discuss the differences.

I'm not sure breaking it down into smaller stories is necessary. The high estimates just mean the team has more work to do, not that the user story is poorly understood.

I think option A is the best choice because all estimations are high, indicating a lack of understanding or need to break down the user story.
