Why is it important to include all stakeholders when building a context diagram?

Including all stakeholders when building a context diagram is crucial because it ensures that all requirements and deliverables are captured effectively. A context diagram serves as a high-level representation of a system, delineating the interactions between the system and external entities. Each stakeholder often has unique insights, expectations, and needs regarding the system, which can significantly influence the overall requirements.

By engaging all relevant stakeholders, the team gains a comprehensive understanding of what needs to be included in the system representation. This collaborative approach helps to prevent misunderstandings or omissions that could arise if some perspectives were left out. Subsequently, having a well-rounded set of requirements leads to better planning, design, and implementation, which ultimately supports project success and aligns the end product with user needs.

While ensuring compliance with regulations, enhancing creativity, or minimizing time are important considerations in project development, they do not capture the core importance of inclusivity in requirement gathering as effectively as ensuring that all relevant requirements and deliverables are captured.
