COEPD – Center of Excellence for Professional Development Happy Learning
Business requirements document is referred to as a BRD. Various product management documents are created at different stages of the project life cycle. It serves as a tool for project planning and provides instructions for project development. The business analyst gathers and sorts the requirements from the primary end users and relevant business stakeholders during the project’s first phase, where BRD is created. All of the high-level business specifications that must be followed during the project are listed in the BRD. BRS, or business requirements specification, is another name for this document. In order to establish a new application or replace a legacy business application, business requirement documents (BRDs) are typically prepared. The BRDs are also drafted for a Request for Proposal (RFP) for a new project.
The BRDs give all project stakeholders a thorough understanding of the requirements. The BRDs establish the groundwork for the project’s successful execution since they ensure that all project participants are focused on addressing business needs. It is well-structured and free of technical jargon. In order to readily consume the functional, quality, and usability needs for future analytical, architectural, and design activities as well as, most significantly, in a format that is understandable by all business stakeholders, a document containing these requirements is needed.
The BRD is designed to take the reader from a high-level understanding of the business processes down to the detailed business requirements.
It should capture the following:
• Project summary and background
• Project scope
• Operating model
• Project governance
• Business process model
• Use cases
• Assumptions and constraints
• Prioritized requirements
• Success metrics
Software Requirement Specification: One of the key documents for the development team is the Software Requirement Specification, or SRS Document. It is an in-depth description of how a system’s behaviour will be transformed. It outlines the conditions that must be met in order to serve the needs of the business. With the help of use cases, it additionally describes every user interaction with the system.
SRS document contains all the functional and non-functional requirements along with the use cases that the software must meet. It covers all necessary business requirements as well as system characteristics, limitations, and behaviours, such as system reliability, response time, storage requirement, as a result, it is also utilised for estimating the cost and efforts required for creating that software.
Simply put, a software specification requirement document expands on the business needs listed in a BRD to account for both functional and non-functional requirements as well as user interactions with the system, or use cases.
The project management, development, and implementation teams have referenced to and helped create this document, which was created by system analysts or business analysts. This document is also known as a product requirements document (PRD) and a system requirements specification (SRS).
COMPARISON OF BRD AND SRS
• The high-level business requirements of a system to be created are included in a BRD or BRS in simple terms. Use Cases and functional and non-functional requirements are included in the SRS document.
• During the project’s analysis phase, a BRD document is created. SRS documents are generated at the project’s planning stage.
• Business Conditions Document is created for stakeholders, business users, etc. The SRS document is created for the technical leads and subject matter experts.
