A Functional Design Specification (FDS) is a detailed document that defines how a system will function, outlining its logic, features, and interactions with users and other systems. It translates high-level requirements from a User Requirement Specification (URS) into a clear operational blueprint for system design and implementation.
Requirement Analysis
The process starts with a thorough review of the approved User Requirement Specification (URS)
Defining Functionality
Each user requirement is broken down into specific, detailed functions that describes every operation, such as data inputs, calculations and system outputs
Specifying System Interfaces
It defines how the proposed system will connect and communicate with other existing systems
Translating Needs into Functional Design
