Systems Engineering (SE) technical process by which operational requirements and inputs from stakeholders are translated into a set of top-level technical requirements. The objective is to ensure stakeholder requirements are feasible, balanced and integrated as information is learned through requirements analysis. Requirements are decomposed during Requirements Analysis to produce a complete set of system functional and performance requirements. The process ensures stakeholders' requirements, expectations and perceived constraints are understood from the acquisition perspective. Failing to perform this process could result in requirements creep, rework due to misunderstanding of end-user needs, unexpected contract modifications, cost growth and schedule slip, it bridges the gap between identification of a materiel need and acquisition of a materiel solution. Stakeholder Requirements Definition complements the Requirements Analysis and Architecture Design technical processes.
