Overview During the Requirements Analysis Phase, the business requirements that were previously documented during the Concept and Planning phases are revalidated and decomposed into functional and nonfunctional system requirements that define the application in more detail with regard to inputs, outputs, processes, and interfaces. If a database is a required component of the application, the Logical Data Model, which was initiated in the Planning phase, is completed and the initial strategy for validation is begun. One outcome of this phase is the Project Schedule, which was established in the Planning phase with high-level milestones, is fleshed out and baselined with specific tasks being identified. In addition to business and system requirements, preliminary information surrounding information security is gathered and documentation initiated. The Requirements Analysis Phase ends with a review to determine readiness to proceed to the Design Phase. Review A Requirements Review is performed to ensure the requirements satisfy the business need and are documented adequately for subsequent design and development activities. For specifics on this review, please refer to ILC Reviews, please refer to ILC Reviews (see Related Links Inside CMS). Artifacts A Requirements Document and Logical Data Model are completed and a Project Schedule is baselined.
