Functional Analysis and Allocation

In the Systems Engineering Process Functional Analysis and Allocation bridges the gap between Requirements engineering and design ^{[citation needed]}.

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.
