List the functional requirements for each functional requirements group. Once a basic functional decomposition diagram has been developed it becomes possible to consolidate To-be Business functions and services. Functional decomposition is a term that engineers use to describe a set of steps in which they break down the overall function of a device system or process into its smaller parts. Functional decomposition refers broadly to the process of resolving a functional relationship into its constituent parts in such a way that the original function can be reconstructed from those parts by function composition.
