Empirical Process Control

Correct Answer: Enhance 'Transparency' by making all information about the recurring error visible to the entire team. Analyze patterns to understand its root cause, and collaboratively decide on adaptations for resolution.

The correct answer utilizes the Empirical Process Control principle of 'Transparency', which is fundamental in Scrum. By making the details of the recurring error transparent, the team can better inspect and adapt their process to prevent it in the future. The wrong answers, although related to Scrum and sound plausible, either divert from directly engaging with the Empirical Process Control (e.g., forming a specialized task force) or misapply Scrum artifacts and events (e.g., increasing review frequency, modifying the Definition of Done for a specific error), which may not effectively address the root cause of the problem.

Correct Answer: Re-assess the task with the team, break it into smaller, manageable chunks if possible, and decide if any parts can be completed within the current sprint or moved to a future sprint.

In Scrum, when a task is found to be larger and more complex than originally estimated, it is important to work empirically. This involves inspecting the current situation (understanding the task's complexity), adapting the sprint backlog if necessary (by breaking down the task, re-prioritizing, or moving it to future sprints), and ensuring transparency in communication among the Development Team and with stakeholders. Extending sprints, overloading the team, or focusing exclusively on the complex task at the expense of the sprint goal contradicts Scrum values and principles. The goal is to maintain the sprint's cadence and adapt the work plan to meet goals more effectively, ensuring sustainable development practices and stakeholder satisfaction.

Correct Answer: Implement a WIP limit to keep the team focused and improve flow efficiency.

Through Empirical Process Control, the Scrum Master has identified that there is too much work-in-progress causing a delay in delivering tasks. The best solution to this problem as per Agile/Scrum methodology is to implement a Work-In-Progress (WIP) limit. This helps keep the team focused and improve the flow efficiency, ensuring that work is completed before starting new tasks. Let's explore why the other options are not as suitable: Adding more members to the team seems like a quick fix, but could cause more complexities and delay due to the need to bring new members up to speed. Also, this solution might not address the root cause of the issue. Decreasing the sprint duration could result in even more pressure, not allowing the team enough time to complete quality work, and request for overtime is not a sustainable solution as it can lead to team burnout and decreased productivity over time.
