    Study Notes

    Software Requirements Definition

    • Software requirements analysis is critical for ensuring software projects meet stakeholder and user needs.
    • It involves gathering, documenting, and analyzing the requirements.

    Defining Requirements

    • The process begins with reviewing functional and performance requirements.
    • System requirements are allocated to software for further refinement.

    Steps for Defining Requirements

    • Identify stakeholders involved in the project.
    • Collect all requirements from stakeholders.
    • Categorize requirements into functional, non-functional, and domain categories.
    • Interpret and record requirements in a clear and concise manner.
    • Obtain sign-off from stakeholders to ensure agreement.

    Software Requirements Development

    • The process involves analysis, use cases, functions, architecture, integration, Verification, and Validation.

    Requirements Analysis

    • A step-by-step process to develop detailed requirements for software work products.
    • Aims to fulfill high-level user requirements, allocated system requirements, and operational concepts.

    Use Cases

    • Describe the flow of operations for system and software implementation.
    • Define limitations based on target computers, execution strategies, and operating systems.

    Functions and Architecture

    • Analysis ensures understanding of software performance and functionality.
    • Identifies and evaluates reusable software components.

    Integration

    • Transforms functional architecture into optimal design solutions.
    • Employs disciplined interface management principles for resource planning and systems integration.

    Verification and Validation

    • Reviews software requirements to ensure accuracy and completeness.
    • Prioritization of requirements helps allocate resources for verification and validation.

    Keeping Track of Changes

    • The Requirements Traceability Matrix helps track requirements and associated test cases.
    • Links requirements with derived product specifications and test cases.

    Software Requirements Documentation

    • Includes software requirements, use cases, and derived requirements.
    • Documented according to development plans, software processes, and product standards.

    Types of Software Requirements

    • Functional Requirements: Define specific functionalities expected from the system.
    • Non-functional Requirements: Specifies quality constraints and performance standards.
    • Domain Requirements: Requirements specific to a particular project category or domain.

    Advantages of Classifying Requirements

    • Improved organization and communication.
    • Increased quality and traceability.

    Disadvantages of Classifying Requirements

    • Complexity and rigidity.
    • Potential for misclassification.
