Analysis
The analysis phase of requirements development ensures that the requirements discovered in the elicitation phase have been articulated correctly and have the correct format, level of detail and properties, and form a correct and cohesive set. As a result of the disparate sources and methods of elicitation the requirements recorded in the elicitation phase will need some massaging and balancing - it is quite common for example, to find repeated or overlapping requirements or for a systems engineer to inadvertently have omitted to record the concerns of one or more stakeholders. Tools such as the Relationship Matrix and the Traceability window will help reveal omissions and issues with requirements. The Discuss & Review window and Chat & Mail window - including the Model Mail facility - will also provide mechanisms for discussing, reviewing and chatting about the Requirements with other team members.
