What is the purpose of decision analysis in requirements analysis?

The purpose of decision analysis in requirements analysis is to evaluate and rank design options based on specific criteria, allowing stakeholders to make informed choices. This process involves identifying various options, assessing their merits and drawbacks, and systematically comparing them to determine which one best meets the project's objectives and stakeholder needs. Decision analysis helps streamline the decision-making process by providing a clear framework for prioritizing options based on factors like feasibility, cost, benefits, and risks.

In comparison to other activities, the focus of decision analysis is more on the systematic evaluation and prioritization of existing options rather than on generating new ideas, facilitating discussions, or developing stakeholder requirements directly. The emphasis is on making choices that align with strategic goals and ensuring that the selected design option will effectively meet the defined requirements.
