Best Practice : F/A-18 Requirements Management
McDonnell Douglas Aerospace (MDA)-St. Louis applies a process in the F/A-18 E/F program (Figure 2-2) that uses a program-wide requirements database to serve as the source for all requirements documentation. The process is iterative and consists of four elements: identification, allocation, implementation, and verification. The primary management tools are a series of matrices that define and document allocations of requirements to design elements, downward flow of requirements to lower levels of detail, and the methodology used to verify proper implementation of each contract requirement.
The process involves three key types of matrices. The Requirements Allocation Matrix is used to manage the allocation and implementation of each requirement. The Derived Requirements Allocation Matrix follows from the Requirements Allocation Matrix and is used to manage MDA-St. Louis internal requirements. The Requirements Verification Matrix manages the association of requirement-to-verification methodology and program milestones. These matrices are used to produce a MIL-STD-490 format Requirements Allocation Document and support the completion of the Functional Configuration Audit.
As the F/A-18 E/F program moves into production, this requirements management process provides electronic requirement-based analysis of potential changes, affording management with better insight into change impact prior to implementation. The requirements database supports the assessment of how well a design satisfies a requirement, and verification of the satisfaction of a requirement. The process, database, and management tools are used to support Integrated Product Development and can be accessed by MDA-St. Louis, Northrop Grumman Corporation, and selected MDA subcontractors.
