Consider an estimation session where a six-member Agile team (Memb1, ... , Memb6) is performing a planning poker session to estimate a user story (in story points). Team

members are using a set of cards with the following values: 1, 2, 3, 5, 8, 13, 21. Below is the outcome produced by 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 as the arithmetic mean of all the estimates made by the team members during this first round, without the need to perform further rounds of estimation

BThe final estimation of the user story in story points is determined as the most frequent estimate value among those selected by the team members (in this case 3 story points chosen by Memb1, Memb2, Memb3, Memb5) during this first round, without the need to perform further rounds of estimation

CThe final estimate of the user story in story points is determined as the arithmetic mean of the most optimistic estimate (chosen by Memb6) and the most pessimistic estimate (chosen by Memb4) during this first round, without the need to perform further rounds of estimation

DMemb4 and Memb6, 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 team members before to proceed to another round of estimation

Answer : D

In Agile estimation sessions, particularly during Planning Poker, the goal is to reach a consensus on the effort required for a user story. The process encourages discussion and collaboration among team members to understand the story's requirements and complexities fully. Here's a breakdown of the options and why D is the correct choice:

Option A: Calculating the arithmetic mean of all estimates.

This method is straightforward but does not facilitate team discussion or consensus-building. It merely averages out the estimates without addressing the reasons behind the varying estimates. Thus, important insights and understanding of the task complexity might be missed.

Option B: Selecting the most frequent estimate value.

While this approach acknowledges the majority's opinion, it ignores the minority views, which might highlight significant aspects of the story that need consideration. It doesn't ensure that all perspectives are considered and discussed.

Option C: Calculating the mean of the most optimistic and pessimistic estimates.

This approach considers the extremes but again lacks the team discussion and consensus aspect. It also assumes that the extreme values alone can balance out the estimate, which might not always capture the true complexity or simplicity of the task.

Option D: Discussing the most pessimistic and optimistic estimates.

This approach fosters team collaboration and understanding. Memb4 and Memb6 explain their reasoning for the highest and lowest estimates, respectively, which can reveal different perspectives on the task's complexity. This discussion helps the team align their understanding and often leads to a more accurate and agreed-upon estimate in subsequent rounds.

In conclusion, the main goal of Agile estimation techniques like Planning Poker is to encourage team communication and collaboration to ensure that all aspects of the user story are considered. Option D best aligns with this goal by promoting discussion and consensus.

Question 2

Which of the following statements is CORRECT?

ATesting the software under test (SUT) based on the design is black-box testing whereas testing the input-output behaviour is experience based testing.

BTesting the software under test (SUT) is possible only after implementation in white-box testing whereas testing the software even before implementation is possible in exploratory testing.

CTesting the software under test (SUT) using knowledge of the tester is experience based testing whereas testing the specification based behaviour without pre-written test cases is using black-box testing techniques.

DTesting based on the structure of the software under test (SUT) is white-box testing whereas testing the input-output behaviour without pre-written test cases is experience based testing.

Question 3

Which ONE of the following statements is correct?
