1. What is BRD? How is it different from SRS?

In the software development, requirements gathering plays a vital role in ensuring successful project outcomes. Two commonly used documents in this context are the Business Requirements Document (BRD) and the Software Requirements Specification (SRS). While both serve as critical project objects, they differ in their scope, purpose, and audience.

Business Requirements Document (BRD) :The BRD serves as a foundational document in software development projects. It captures the business needs and objectives that drive the development process. BRDs are typically prepared by business analysts or product owners and serve as a formal communication channel between stakeholders and the development team.

Key Characteristics of BRD:

Scope: BRD outlines the high-level business requirements and objectives of a project. It focuses on the “what” and “why” of the software solution rather than specific technical details.

Stakeholder-oriented: BRDs are primarily targeted at business stakeholders, such as clients, users, and management. It aims to capture their needs, expectations, and constraints, ensuring alignment between business objectives and software development efforts.

Non-Technical Language: In BRDs non-technical language are used to ensure clear communication with a wide range of stakeholders. They focus on business processes, workflows, user roles, and overall system behaviour.

Flexibility: BRDs are often subject to change during the software development lifecycle. They provide a framework for capturing evolving business requirements and facilitate ongoing discussions and refinements.

Components of BRD:

Executive Summary: Provides a high-level overview of the project, including its purpose, goals, and stakeholders.

Business Objectives: Clearly defines the desired outcomes, business benefits, and success criteria of the project.

Functional Requirements: Describes the high-level functionalities and features required to meet the business objectives.

Non-Functional Requirements: Specifies the quality attributes, constraints, and performance expectations of the software solution.

User Stories: Narratives that capture specific user interactions and scenarios, helping to articulate user needs and goals.

Assumptions and Constraints: Highlights any assumptions made during requirements gathering and identifies limitations or constraints that may impact the project.

Software Requirements Specification (SRS) The Software Requirements Specification (SRS) complements the BRD by providing a detailed, technical blueprint of the software system. It serves as a bridge between the business and technical teams, providing clear guidelines for the development process.

Key Characteristics of SRS:

Scope: SRS focuses on the detailed functional and non-functional requirements of the software solution. It specifies the features, interfaces, system behavior, and technical aspects needed for implementation.

Technical Audience: SRS is primarily intended for the development team, including software architects, engineers, and testers. It provides the necessary technical specifications to guide the design, development, and testing phases.

Technical Language: Unlike BRDs, SRS utilizes technical terminology and diagrams to convey specific system requirements accurately.

Precision and Completeness: SRS aims to provide a comprehensive and unambiguous description of the software system. It includes use cases, data models, flowcharts, and other artifacts that aid in precise implementation.

Components of SRS:

Introduction: Provides an overview of the document, its purpose, and the intended audience.

Functional Requirements: Defines the detailed functionalities, inputs, outputs, and system behavior.

Non-Functional Requirements: Specifies the performance, security, usability, and other quality attributes of the software.

System Architecture: Describes the overall system architecture.
