What is Software Requirement Specification (SRS)? 

Software Requirements Specification (SRS) is a comprehensive document that outlines the functionality, constraints, and attributes of a software system. It serves as a formal agreement between stakeholders and developers on what the software will achieve and how it will operate.

Key Aspects of SRS:

1. Purpose: Defines what the software system should do, including both functional and non-functional requirements. It sets clear expectations for both developers and stakeholders.

2. Content:

   • Functional Requirements: Describes specific functionalities the system must provide (e.g., user authentication, data processing).
   • Non-Functional Requirements: Includes performance, security, usability, and other quality attributes (e.g., response time, security standards).
   • Constraints: Lists limitations such as hardware, software, regulatory, or environmental constraints.
   • Use Cases: Illustrates how users will interact with the system through scenarios or user stories.

3. Audience: Intended for various stakeholders, including developers, testers, project managers, and clients, ensuring a shared understanding of what the system will deliver.

4. Documentation: Provides a detailed and structured description of the system, which serves as a reference for design, implementation, and testing phases.

5. Validation: Acts as a basis for validating and verifying that the system meets the specified requirements, guiding the development and testing processes.
