Functional Specifications

Functional specifications are critical to product design.

The FSD clearly and accurately describes the essential technical requirements for services including the procedures by which they can be determined that the business’ requirements have been met. Functional Specifications help avoid duplication and inconsistencies, allow for accurate estimates of necessary work and resources, act as a reference document for engineering changes, provide documentation of configuration, and allow for consistent communication among those responsible. They provide a precise idea of the problem to be solved so that they can efficiently design the system and estimate the cost of design alternatives. They provide guidance to testers for verification (qualification) of each technical requirement.

The Functional Specifications focus on what various outside agents (people using the program, computer peripherals, or other computers, for example) might “observe” when interacting with the system.
