Functional Specification Document

A Functional Specification Document (FSD) is a detailed blueprint that describes what a software or system should do. It outlines the features, behaviors, and requirements from the user's perspective, ensuring all stakeholders understand how the system will function. Think of it like a detailed instruction manual that guides developers on what to build, how it should behave, and how users will interact with it. The FSD helps ensure everyone involved has a clear, shared understanding, reducing misunderstandings and guiding the development process effectively.
