Final answer:
The requirements validation activity occurs primarily after the Analysis activity. This involves checking the requirements against the criteria and constraints, and ensuring that they are complete, consistent, and feasible.
Step-by-step explanation:
The requirements validation activity occurs primarily after the Analysis activity. Once the requirements for a project have been analyzed, it is important to validate that they accurately reflect the needs and goals of the project. This involves checking the requirements against the criteria and constraints, and ensuring that they are complete, consistent, and feasible.
Validation activities can include reviewing the requirements with stakeholders, conducting simulations or prototypes, and performing inspections or walkthroughs. These activities help to confirm that the requirements are correct and suitable for implementation.
For example, after the Analysis activity, a software development team may review their requirements document with the client to validate that the proposed solution meets their expectations and requirements.
