Functional Specification Document (FSD)

A Functional Specification Document (FSD) is a detailed blueprint that describes how a software or system should work. It outlines the features, functions, and behavior the product must have to meet user needs and business goals. The FSD provides clear instructions for developers, ensuring everyone understands what to build, how it should perform, and any specific requirements or constraints. It acts as a common reference, reducing misunderstandings and helping ensure the final product aligns with expectations. Essentially, it translates ideas into detailed plans for successful development and implementation.
