Functional Analysis and Allocation
In the Systems Engineering Process Functional Analysis and Allocation bridges the gap between Requirements engineering and design. This step in the process transforms stakeholder requirements into a logical[1] and functional architecture[2], and provides the inputs to the design, integration, and verification activities [3][4]
There are several methodologies for performing this process. However, the inputs and outputs of the process are common to all methodologies. The Functional Analysis and Allocation Process starts with a list of functional requirements as elicited from the Requirements Engineering process and ends with the System Functional Architecture of the system.
