Hi,
You can follow below steps:
A functional design document (FDD) is a document that outlines the functional requirements and design of a system or software application. It typically includes detailed information about the functionality of the system, user interfaces, data structures, algorithms, and performance requirements.
Here are some key elements that are typically included in a functional design document:
Introduction: This section provides an overview of the system and its purpose.
Functional Requirements: This section outlines the features and functionality required of the system, including any business rules or workflows.
User Interfaces: This section describes the interface design, including wireframes and mockups of screens, menus, and dialog boxes.
Data Structures: This section defines the data structures and database design, including tables, fields, relationships, and indexing.
Algorithms: This section outlines the algorithms used in the system, including flowcharts and pseudocode.
Performance Requirements: This section specifies the performance requirements of the system, including response times, throughput, and scalability.
Error Handling and Recovery: This section defines how the system will handle errors and recover from failures.
Security: This section outlines the security requirements and measures that will be implemented to protect the system and its data.
Implementation Plan: This section describes the implementation plan, including timelines, resources, and dependencies.
Testing Plan: This section outlines the testing plan, including test cases and scenarios, and how testing will be conducted.
Overall, the functional design document serves as a blueprint for the development team, guiding the implementation and testing of the system or application.
