Capacity Planning

Correct Answer: Load testing

Load testing is the most suitable system analysis in the given context. Load testing is designed to test the system by continuously and steadily increasing the load on the system until it reaches the threshold limit. It helps in identifying the maximum operating capacity of an application increasing understanding of any bottlenecks that can interfere with its performance. Other answers are not correct because, Regression testing is used to confirm that a recent program or code change has not adversely affected existing features, Functional testing is a type of testing which verifies that each function of the software application operates in conformance with the requirement specification, and Smoke Testing is preliminary testing to check whether the implemented software is working or not. None of these directly address the identification of system bottlenecks under high loads.

Correct Answer: Review the team's velocity, reconsider estimations, and adjust the number of story points designated for each sprint.

The best capacity planning strategy to adopt when a Scrum team consistently ends sprints with unfinished user stories, is to review the team’s velocity, reconsider estimations, and adjust the amount of story points allocated to each sprint. This strategy allows the Scrum Master to better match the team's actual productivity levels and streamline their work process. The other options are not the best strategies. Asking the team to take fewer breaks might increase productivity in the short term, but it could lead to burnout and decreased productivity in the long term. Questioning the commitment and skills of team members can demotivate them and could negatively impact their performance, instead of helping. And, increasing the sprint duration to accommodate more work is not a recommended strategy because it does not address the root cause of the issue, which is incorrectly estimating the quantity of work to be done in the planned sprint timeframe.

Correct Answer: Plan the next sprint considering the reduced capacity and reprioritize the backlog accordingly.

The best way to handle the situation when a Scrum team member is on a long vacation, thereby reducing the team's capacity, is to plan the next sprint considering the reduced capacity and reprioritize the backlog accordingly. This is because Scrum is based on sustainable development, and expecting the remaining team members to work extra to cover for the absent member is not sustainable or fair. Insisting the team member works remotely during their vacation is not appropriate or ethical, as it invades their personal time and may lead to burnout or resentment. Distributing the absent member's tasks evenly among the team without adjusting the sprint scope may overload the team members, potentially compromising the quality of work and damaging team morale.
