Feature Driven Development (FDD)

Correct Answer: Inspect and adapt the JIT process to bring balance between recognizing changes early and flexibility in the process.

The best response to this scenario would be to inspect and adapt the Just-In-Time (JIT) process to bring a balance between recognizing changes early and maintaining flexibility in the process. The Scrum Master's role isn't just to ensure adherence to Scrum but also to create an environment where the team can be highly productive while delivering quality products. When an issue arises, like the required amendments in the design not getting updated due to the JIT approach, the Scrum Master should engage in continual process optimization by inspecting the current process and adapting it as necessary to achieve the desired effect. Ignoring the amendments and continuing working on the old design would not help in resolving the issue at hand, hence this is not a good solution. Furthermore, forcing the team to work overtime might lead to a decrease in product quality and team morale which again would be counterproductive. Finally, switching entirely to a new design approach and abandoning JIT, would be a drastic measure and should only be considered if the JIT design/build approach has proven to inhibit the team's capability consistently and after several attempts at refinement have been unsuccessful. Therefore, analyzing the situation and adapting the process to cater to the team's needs for flexibility and early change recognition would be the most reasonable step to take in an Agile work environment.

Correct Answer: Establish a bidirectional relationship between Departments and Professors. Courses are owned by Professors but can be observed by Departments.

In an Object-Oriented context, it makes sense for the Department to have a relationship to Professors where a Department can have multiple Professors working in it, and each Professor can be associated with multiple Departments, hence a bidirectional relationship. This maintains coherence as these entities are closely associated in real life scenarios. Courses are created and managed by Professors and so they 'own' them. However, Departments would also need to 'observe' or have access to information about these Courses for administrative and other purpose, maintaining encapsulation properties of Object Orientation. The answer that suggests that Professors should be independent objects and Departments should hold a list of courses is incorrect because it omits the relationship between Professors and Departments, and does not allow for Professors to 'own' their Courses, which is a more accurate interpretation of the domain model. The answer that suggests Professors should own Departments does not accurately represent the real-life relationship between these entities. In reality, a Department is an administrative unit of a University, and while Professors are vital stakeholders, they do not 'own' Departments. Lastly, the answer that suggests to establish relationships only between Professors and Courses and let Departments be independent does not accurately represent the role a Department plays in academia. In a real-life model, Departments are not independent units, they are closely tied to both Professors and Courses.

Correct Answer: Schedule regular checkpoints to review, clear doubts, and make necessary adjustments, while still giving enough time for the team to work on the modeling.

In an Agile environment, it is important to adapt to changes and improve through regular iterations. Scheduling regular checkpoints allows for frequent validation, clarification and adjustment of the model, ensuring it continues to meet changing requirements, and minimizes the risk of investing time on aspects that may eventually change or be deemed unnecessary. This approach is consistent with Agile principles, which promote regular reflections for self-improvement. The other options do not address the issue in a healthy Agile context. Switching back to traditional modeling may ignore the benefits of the color-modeling. Ignoring the delay could lead to more problems in the future due to compounded misalignment with project requirements. Asking the team to work overtime can lead to burnout and is not sustainable for long-term productivity.
