A System Requirements Review (SRR) is a formal review conducted to ensure that system requirements have been completely and properly identified and that a mutual understanding between the government and contractor exists. It ensures that the system under review can proceed into initial systems development and that all system and performance requirements derived from the Initial Capabilities Document (ICD) or draft Capability Development Document (CDD) are defined and testable, and are consistent with cost, schedule, risk, technology readiness, and other system constraints.

A SRR assesses the system requirements captured in the system specification and ensures that the system requirements are consistent with the approved materiel solution, ICD, enabling concepts, and available technologies identified in the Materiel Solutions Analysis (MSA) phase. An SRR is important in understanding the system performance, cost, and scheduling impacts that the defined requirements will have on a system.
Completion of the SRR should provide the following:
- An approved system performance specification with sufficiently conservative requirements to provide for design trade space for the Engineering, Manufacturing, and Development (EMD) phase,
- A preliminary allocation of system requirements to hardware, human, and software subsystems,
- A preliminary Identification of all software components (tactical, support, deliverable, non-deliverable, etc.),
- A comprehensive risk assessment for EMD,
- An approved EMD phase Systems Engineering Plan (SEP) that addresses cost and critical path drivers, and
- An approved Life-Cycle Sustainment Plan (LCSP) defining the product support plan and sustainment concepts with the corresponding metrics.
The SRR reviews and evaluates the draft functional baseline and requirements analysis. All relevant documentation should be reviewed, including:
- Feasibility Analysis (results of technology assessments and trade studies to justify system design approach)
- System Operational Requirements
- System Maintenance Concept
- Functional Analysis (top level block diagrams)
- Significant system design criteria (reliability, maintainability, logistics requirements, etc.)
- Draft System Specification and any initial draft Performance Item Specifications
- Systems Engineering Planning
- Test and Evaluation Master Plan (TEMP)
- Draft top-level Technical Performance Measurements (TPM)
- System design documentation (layout drawings, conceptual design drawings, selected supplier components data, etc.)
Note: IEEE 5288.2 “Standard for Technical Reviews and Audits on Defense Programs” is the standard for technical reviews and audits to be performed throughout the acquisition life cycle for the US Department of Defense (DoD) and other defense agencies. This standard guides the DoD and contractor on what is required during an SRR.
