The table summarizes the three types of requirement documents: BRD, FRD, and SRS.

Detailed Explanation

This chunk introduces a table that compares three types of requirement documents used in project management: the Business Requirements Document (BRD), Functional Requirements Document (FRD), and the Software Requirements Specification (SRS). Each document serves a distinct purpose and is meant for different audiences, emphasizing the unique focus areas and the intended users of each document.

Examples & Analogies

Think of these three documents as different maps for a trip. The BRD acts like a roadmap showing the overall destination and key landmarks (business needs), the FRD provides detailed directions and routes for the journey (specific functionalities), while the SRS includes travel tips and necessities for the journey like rest stops and gas stations (comprehensive specifications).
