Tell me about the stages of requirements elaboration and what determines the depth of elaboration.

The stages of requirements elaboration typically include:

1. Requirements gathering: interviews with stakeholders, users, analysis of documentation.
2. Requirements analysis: identifying conflicts, clarifying details, assessing feasibility.
3. Documentation: creating specifications, user stories, use cases.
4. Validation: aligning requirements with the client, checking completeness and correctness.
5. Change management: tracking and handling changes in requirements.

The depth of elaboration depends on:

• Project complexity: the more complex the system, the more detailed the elaboration needed.
• Team experience: experienced teams can work with less detailed requirements.
• Risks: high-risk projects require thorough elaboration.
• Time and budget constraints: sometimes a balance must be struck between depth and deadlines.
• Development methodologies: for example, Agile allows for more flexible and iterative requirements, while Waterfall is more detailed from the start.
