BCS CTFL4 Exam - 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.

But what if the business rep misunderstood the requirements?

Wait, why is everyone so sure about option B? Seems off.

I think we should definitely discuss the estimates more, so option D makes sense to me, but I’m not sure if we should repeat the round or just clarify first.

I feel like the business representative's view is important, but I don't think we should just go with option C without discussing the differences first.

I'm a bit unsure, but I think the rules we set mean we have to go with the highest score, which would be option B.

I remember we talked about how high estimates can indicate a lack of clarity in the user story, so option A seems reasonable.

I'm a bit confused about whether we should go with the business representative's estimate or the highest one. I'll need to think through the pros and cons of each approach.

The fact that all the estimates are on the higher end makes me think the user story might need to be broken down. I'll make a note to discuss that possibility.

Okay, so the team agreed to use the highest score for estimation. That seems straightforward enough, but I wonder if there's more to consider here.

Hmm, this one seems tricky. I'll need to carefully review the ground rules they agreed on to determine the next best action.

I think the key here is to follow the pre-agreed rules. Since the highest score is Extra-extra-large, that's what we should use for the estimation. Simple as that.

I'm a little confused on this one. Is the Charpy test the same as the guided bend test? Or are those two different things? I'll have to make an educated guess on this.

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.

The pre-agreed rules seem clear to me - we should use the highest score, which is Extra-extra-large. No need to overthink this.

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.
