What type of information does document analysis provide in requirements analysis?

Document analysis plays a critical role in requirements analysis by providing insights that support design decisions. Specifically, it gives access to existing documentation that can include requirements specifications, user manuals, design documentation, compliance documents, and similar resources. By reviewing these texts, analysts can gather essential details that describe design options, including constraints, previous design decisions, rationale behind them, and lessons learned from earlier projects.

This information is crucial for ensuring that the design is aligned with both the technical capabilities and the needs of the stakeholders, facilitating informed decision-making that enhances overall project quality. Other options might provide valuable insights, but they do not directly relate to how document analysis contributes to defining and refining design options within the requirements analysis process.
