The Requirements Engineering (RE) Framework is a structured approach used by business analysts to define, document, and manage requirements. It consists of five iterative stages: Investigate Situation, Consider Perspectives, Analyze Needs, Evaluate Options, and Define Requirements .

Key Considerations:

Suitability for Waterfall Projects Only: The RE Framework is flexible and can be adapted to both waterfall and Agile methodologies.

Iterative Stages: The framework emphasizes iteration and refinement, making it suitable for evolving requirements.

Defining Requirements: The framework explicitly supports the definition and management of requirements.

Sequential Steps: While the stages are presented in a sequence, they are iterative and not strictly linear.

Evaluation of Each Option:

A. It is only suitable for use with waterfall projects:The RE Framework can be applied to both waterfall and Agile projects.Conclusion: This is not correct .

B. It shows five iterative stages that a business analyst needs to carry out to establish the requirements:This accurately describes the RE Framework's structure and purpose.Conclusion: This is correct .

C. Using the Requirements Engineering Framework does not help to define requirements:The framework is specifically designed to define and manage requirements.Conclusion: This is not correct .

D. It shows steps in the requirements engineering process that a business analyst must follow sequentially:While the stages are presented in a sequence, they are iterative and not strictly sequential.Conclusion: This is not correct .
