MY-STAR - A METHODOLOGY AND SYSTEM FOR TRACING AND ANALYZING REQUIREMENTS

This paper describes a methodology developed at the Jet Propulsion Lab oratory (JPL), and designed for the process of requirements engineerin g and management. MY-STAR provides techniques for specifying, refining , allocating, baselining, sharing, changing, storing and reporting on requirements and requirements metrics. In support of MY-STAR, the tool STAFR (System for Tracing and Analyzing Functional Requirements) has been prototyped by the Ground Systems Group (Software Product Assuranc e) as part of the process assurance support to four different projects within the Deep Space Network (DSN) at JPL. The results show that STA FR provides an effective means for capturing in one place requirements , while enabling refinement, analysis, traceability of test cases to r equirements, and other trade-off artifacts associated with the specifi cations, prioritization, allocation and planning of requirements. It d oes so without the significant overhead typically associated with know ledge-based systems.
