Incremental Development

Correct Answer: Incorporate solving the issue into the tasks of the next increment, adjusting the planned increments as necessary.

The correct answer is 'Incorporate solving the issue into the tasks of the next increment, adjusting the planned increments as necessary'. In an incremental development approach, work is divided into smaller sections or 'increments'. Each increment represents a portion of the total required functionality and can be developed and tested independently. If an unexpected issue arises, it should be addressed in the planning and task assignment for the next increment. The answer 'Ignore the issue and proceed with the next increments as planned' is incorrect, as ignoring the issue could lead to further problems down the road. It's best to address issues as they are discovered to prevent them from impacting the overall project. 'Shift the entire project plan to accommodate the issue' is also incorrect because it would involve a significant change which is not necessary for addressing one technical issue. In the Agile Scrum methodology, the goal is to adapt and respond to changes in the development process, but overhauling the entire project plan is generally not the preferred approach Finally, 'Launch the increment with the technical issue and fix it in a later version' is not a recommended approach either. This might negatively impact the user experience or the overall functionality of the product.

Correct Answer: Focus on fully developing and delivering a smaller number of features in each increment.

The project manager should advise the team to focus on fully developing and delivering a smaller number of features in each increment, ensuring the increments provide complete and functional value. The other options do not follow incremental development best practices and would not solve the issue of incomplete functionality.

Correct Answer: Include improvements in user interface in the next increment by prioritizing it in the product backlog.

In Scrum, feedback from stakeholders is vital and is used to refine the product backlog and improve the product incrementally. So, the best course of action for the Scrum Master, when receiving feedback about the lack of user-friendly interfaces, would be to 'Include improvements in user interface in the next increment by prioritizing it in the product backlog.' This allows for continuous improvement in subsequent sprints while delivering a potentially shippable product after each iteration. The other answers are incorrect because: 'Ignore the feedback since the increment has already been finished.' - This goes against the principles of Scrum, which greatly values stakeholder feedback. 'Start over the project to accommodate the feedback.' - This isn't a great idea because Scrum values incremental and iterative development, rather than starting from scratch every time some feedback is received. 'Work on the interface, halting all other processes.' - This too is not recommended, as it could delay other important aspects of the project, and the feedbac can be incorporated in upcoming sprints.
