The purpose of the requirements definition phase is to produce a clear, complete, consistent, and testable _( )_ of the technical requirements for the software product.During the requirements definition phase, the requirements definition team uses an iterative process to expand a broad statement of the system requirements into a complete and detailed specification of each function that the software must perform and each _( )_ that it must meet. The starting point is usually a set of high level requirements from the _( )_ that describe the project or problem.In either case, the requirements definition team formulates an overall concept for the system and then defines _(请作答此空)_ showing how the system will be operated publishes the system and operations concept document and conducts a system concept review (SCR).Following the SCR, the team derives _( )_ requirements for the system from the high level requirements and the system and operations concept. using structured or object-oriented analysis. the team specifies the software functions and algorithms needed to satisfy each detailed requirement.
