System Functional Review
Definition
A formal review of the system conceptual design conducted to establish its capability to satisfy requirements. It establishes the functional baseline.
General/Information/Narrative
The System Functional Review (SFR) is a multi-disciplined technical review to ensure that the system's functional baseline is established and has a reasonable expectation of satisfying the requirements of the Initial Capabilities Document or draft Capability Development Document within the currently allocated budget and schedule. It completes the process of defining the items or elements below system level. This review assesses the decomposition of the system specification to system functional specifications, ideally derived from use case analysis. A critical component of this review is the development of representative operational use cases for the system. System performance and the anticipated functional requirements for operations maintenance, and sustainment are assigned to sub-systems, hardware, software, or support after detailed analysis of the architecture and the environment in which it will be employed. The SFR determines whether the system's functional definition is fully decomposed to its lower level, and that Integrated Product Teams (IPTs) are prepared to start preliminary design.
Completion of the SFR should provide the following:
- An established system functional baseline with traceability to lower-level performance requirements,
- An updated risk assessment for the Engineering and Manufacturing Development (EMD) phase,
- An updated Cost Analysis Requirements Description (CARD) or a CARD-like document based on the system functional baseline,
- An updated program development schedule including system and software critical path drivers, and
- A preliminary system level maintenance plan with updates applicable to this phase.
The program manager should tailor the review to the technical scope and risk of the system, and address the SFR in the Systems Engineering Plan (SEP). The SFR is the last review that ensures the system is credible and feasible before more technical design work commences.

PowerLOG’s LSA Reports can support this effort, providing maintenance information, parts lists, and other logistics data. PowerLOG is a logistics data management system fulfilling Logistics Support Analysis Record (LSAR) requirements defined by MIL-STD-1388-2B, as well as Logistics Management Information (LMI) defined by GEIA-STD-0007. powerLOG supports the development, integration, and review of logistic product information throughout the acquisition life cycle. powerLOG is available free to all Government agencies and their contractors, and can be obtained by visiting: https://www.logsa.army.mil/lec/powerlog/.
The Cost Analysis Strategy Assessment (CASA) Life-Cycle Cost Estimating Software uses an engineering cost model to estimate total cost of ownership based on RDT&E, Acquisition/Procurement, O&S, and Disposal activities. In addition to life-cycle cost estimation, CASA can perform trade-offs, production rate, warranty effectiveness, and other economic analyses. CASA is distributed freely to all US personnel. Request from foreign nations for CASA and associated training and technical support are handled through a Foreign Military Sales Case (FMS). CASA can be obtained here: https://www.logsa.army.mil/lec/casa/.
