It does not address how these functions will be performed.  \n♦ In the early phases of the project life cycle, functional analysis deals with:  \n• The top-level functions that need to be performed by the system;  \n• Where theses functions need to be performed;  \n• How often they need to be performed; and  \n• Under what operational concept and environmental conditions.  \n♦ Later in these early phases, functional analysis proceeds to lower levels of the system decomposition to define the system functional design and interfaces.  \nSpace Systems Engineering: Functional Analysis Module 3  \nWhy Do Functional Analysis?  \n♦ To draw out all the functions the system must perform to meet its requirements.  \n♦ Required for subsequent requirements allocation.  \n♦ To identify profitable trade studies.  \n♦ In describing what must be done and not how to do it, we decouple requirements from implementation. This leaves the implementation trade spaces unbiased.  \nBut “ …decomposition cannot be found in a book or dictated by the stakeholders; the decomposition is a product of the engineers of the system and is part of the architecture design process that is attempting to solve the design problem established by the requirements. The decomposition can be carried out as deeply as needed to define the transformations that the system must be able to perform.”  \nBuede, D. M.
