The Elaboration Phase is the part of the framework when more detailed analysis and planning are undertaken to better understand the problem domain, develop a more concrete project plan, identify and eliminate the high-risk elements of the effort, and to establish a solid architectural foundation for the software to be developed. The goal is to develop a "mile wide and inch deep"
view of the system to be developed.

The speciﬁc activities of this phase include:

- The identification of all actors and use cases, with most use cases having been defined to at least 80% completion (use-case descriptions rather than models)

- Supplementary requirements detailing the non-fu nctional requirements and any requirements not related to a use case are completed

- A Software Architecture Description has been completed

- The business case and risk lists have been updated with higher-conﬁdence information

- The project and development plans have been defined to at least a level that shows all iterations and the evaluation criteria for each iteration

- An executable architecture prototype has been created and approved for use (this may involve creating more than one)

- A preliminary user manual has been created (optional)
