摘要: A method of creating a systems requirement document by using numerical modeling tool, such as spreadsheet, to prototype an operational process in terms picture the goals, metrics, performance targets and constraints used managers process. design blueprint is defined for process, including data sources sinks. representative model created. If not detailed enough implementation IT professionals, objects flows are added modified be consistent with blueprint. Surrogate calculations may made computational task or, alternatively, separate blueprints generated objects. This cycle repeated until implementation.
