The Role of Modeling in Scrum Teams

Modeling can play an important role in enhancing the effectiveness of Scrum Teams by increasing shared understanding among Developers. Although Scrum emphasizes working software over comprehensive documentation, modeling can still be a valuable tool.

Exam Question

What is the role of modeling in Scrum Teams?
(choose the best answer)
A. Models are not used by agile teams.
B. Models are maintained along with software as it emerges.
C. Modeling may be useful to increase shared understanding.
D. Models are assembly instructions for the Developers.

Correct Answer

C. Modeling may be useful to increase shared understanding.

Explanation

Correct Answer

C. Modeling may be useful to increase shared understanding:
In Scrum Teams, modeling can be a valuable practice to enhance communication and shared understanding among team members. While Scrum and other Agile methodologies prioritize working software over detailed documentation, models can still serve as tools to visualize complex concepts, design structures, or workflows. This can help Developers, Product Owners, and other stakeholders align on the approach and ensure everyone has a clear understanding of the system being developed.

Why the Other Options Are Less Appropriate

A. Models are not used by agile teams:
This is incorrect because Agile teams do use models, though they do so sparingly and only when they add value by increasing understanding or solving a specific problem.

B. Models are maintained along with software as it emerges:
While it is true that documentation and models can evolve with the software, this option is less accurate because the primary role of modeling in Scrum is to increase shared understanding, not necessarily to be maintained as part of the evolving software.

D. Models are assembly instructions for the Developers:
This is incorrect because models in Scrum are not typically treated as detailed assembly instructions. Instead, they serve as high-level guides or visual aids to support the understanding of the overall design or architecture.

Relevance to the PSD Exam
