Understanding Requirement Documentation
In project management, clearly defined and well-documented requirements are vital for success, enabling all stakeholders—from business users to developers—to remain on the same page. This section covers the primary types of requirement documents, namely:
1. Business Requirements Document (BRD)
- Definition: The BRD articulates high-level business needs and objectives, addressing the project's 'Why' and 'What.'
- Purpose: To define business goals, secure stakeholder buy-in, and establish a common understanding of the project.
- Key Components Include: Executive Summary, Business Objectives, Scope, Stakeholder List, High-Level Requirements, Assumptions, and Success Criteria. An example business requirement might be: “The system shall allow customers to view previous transactions for up to 12 months.”
2. Functional Requirements Document (FRD)
- Definition: The FRD translates business needs into specific functionalities that the system must fulfill, explaining how the system should operate under various conditions.
- Purpose: To serve as a guide for developers and QA teams, outlining 'what the system should do.'
- Key Components Include: Detailed features, Use Case Diagrams, Data Flow Diagrams, Interface Requirements, Business Rules, and Acceptance Criteria. An example functional requirement could be: “When a user clicks ‘Download Invoice’, the system should generate a PDF with billing details.”
3. Software Requirements Specification (SRS)
- Definition: The SRS merges both functional and non-functional requirements, providing a comprehensive technical description of the system.
- Purpose: To act as a single reference for developers and QA, ensuring clarity and completeness for testing.
- Key Components Include: Descriptions of functional and non-functional requirements, system interfaces, assumptions, and a Traceability Matrix. An example non-functional requirement could be: “The application shall support up to 10,000 concurrent users with a response time < 3 seconds.”
Conclusion
The section emphasizes that a Business Analyst is responsible for gathering, validating, and documenting these requirements, targeting different stakeholders appropriately such as project managers for BRDs and technical teams for FRDs and SRSs. Understanding these documents ensures successful project initiation and execution.
