What is generally included in the requirements architecture?

The requirements architecture is a structured framework that organizes and presents the requirements of a project. It encompasses a collection of views that illustrate different aspects of the requirements, providing a comprehensive understanding of what needs to be achieved. These views can include stakeholder views, functional and non-functional requirements, and various other elements that contribute to the overall clarity and direction of the project.

By incorporating multiple perspectives, the requirements architecture facilitates communication among stakeholders, assists in identifying gaps or overlaps in requirements, and ensures that all areas are covered. This multifaceted approach is key to delivering a successful outcome, as it allows for a thorough exploration and validation of requirements.

In contrast, the other options do not adequately represent the essence of requirements architecture. A single viewpoint would limit the understanding of requirements, an executive summary is typically a brief overview and lacks detailed structure, and a project marketing plan focuses on promoting the project rather than outlining its requirements. Thus, a collection of views best encapsulates the comprehensive and organized nature of requirements architecture.
