Technical Debt

Correct Answer: Allocate a portion of each sprint for addressing technical debt, ensuring compliance with the definition of done.

Allocating specific time for managing technical debt as part of sprint planning ensures that the team consistently addresses obsolete practices while still delivering new features, maintaining a healthy codebase. Increasing the sprint length assumes more time solves the issue, but without focused effort, it may not effectively address the problem. Exclusively prioritizing new features can lead to increased technical debt over time, creating a potential slowdown in future development efforts. While pair programming can improve code quality, it doesn't guarantee the systematic identification and resolution of pre-existing obsolete practices unless explicitly focused on those tasks.

Correct Answer: Initiate a discussion with the team and Product Owner to find a balance between new feature development and addressing technical debt in order to ensure sustainable development.

The best course of action as a Scrum Master when confronted with increasing technical debt causing delays and bugs is to initiate a discussion with the team and the Product Owner. This would aim to find a balance between developing new features and addressing the existing technical debt in order to ensure sustainable development. This is an ideal method because it maintains the agile principle of sustaining a constant pace of development while addressing the issue of technical debt. The other answers are not as viable. Asking the team to work overtime is not a sustainable or healthy solution and can lead to further issues such as burnout down the line. Recommending to skip the next sprint to focus entirely on technical debt might disrupt the product delivery schedule. Furthermore, such an approach is not usually a good practice in agile development since it means that during this period no new value is being delivered to the customers. Recommending an automated software to reduce technical debt assumes that such software exists and would be effective, which may not be the case. Automation can help prevent new technical debt, but it won't necessarily help to reduce the existing one. It also requires time and resources to be developed or implemented, which might be better used in addressing the technical debt directly.

Correct Answer: Organize a backlog refinement session to prioritize the technical debt items and integrate them into the sprint backlog.

As a Scrum Master, addressing technical debt involves working with the Development Team and the Product Owner to understand its impact and plan its resolution in a way that aligns with Scrum principles. Organizing a backlog refinement session to prioritize technical debt allows the team to systematically address it without halting development entirely. Increasing the definition of done does not directly address existing debt, but prevents future debt. Allocating a fixed percentage of time for refactoring is a practical approach but needs to be decided by the Development Team rather than being instructed by the Scrum Master. Halting all new features could have significant business implications and goes against the principle of iterative improvement.
