Study Notes
Software Requirements Engineering
- Requirements engineering is a process focused on understanding and documenting a software project's needs.
- It involves several crucial steps:
Feasibility Study
- Purpose: Evaluates if a project is technically, economically, legally, operationally, and schedule-wise feasible.
- Methods: Conducting cost-benefit analysis, reviewing technical feasibility (resources, skills), operational feasibility (impact on workflow), and legal feasibility (regulatory compliance), plus the project schedule.
Requirement Elicitation/Collection
- Nature: A cyclic (iterative) process that involves gathering information from stakeholders about their needs and the problems the software aims to solve.
- Goal: Understanding the problem that the software is meant to solve and the expectations of stakeholders.
- Initial Step: Identifying all relevant stakeholders.
- Key Stakeholders: Users are frequently the most important.
- Techniques: Gathering data through interviews, surveys, focus groups, and observation.
Requirements Specification
- Purpose: Docudment the collected and analysed requirements in a clear and consistent format.
- Goal: Creating a formal document that describes all aspects of the project's requirements
- Content: A formal requirement specification document (SRS) covers functional requirements, non-functional requirements, and interfaces with hardware, software, and external systems.
Structure of SRS
- Introduction: Contains the project's purpose, scope, intended audience, definitions, and references.
- Overall Description: Describes the system's overall functionality, user interface, system interface, software and hardware requirements, and constraints.
- System Features & Requirements: Details individual system features using functional requirements, use cases, external interfaces, data storage requirements, and non-functional requirements.
- Delivery for Approval: Provides a final check-in point.
Understanding Requirements
- Business Requirements: Defined in a Business Requirements Document (BRD), outlining the software project's goals.
- User Requirements Defined in user-friendly language including operational constraints.
- System/Software Requirements: Expanded from the BRD and user requirements to define specific features and functions that developers can understand.
Requirements Verification and Validation (V&V)
- Purpose: To ensure that the requirements are complete, accurate, and consistent and address stakeholders' needs.
- Validation ensures that the requirements meet user needs.
- Verification checks for correctness of requirements.
Requirements Management
- Purpose: Tracking and managing changes to requirements throughout the project lifecycle.
- Importance: Prevents scope creep, ensures communication with stakeholders, and maintains alignment between requirements and project goals.
- Activities include tracking changes, providing version control, establishing traceability to designs, testing, and validation, communication, and monitoring.
Benefits of Requirements Engineering
- Addresses stakeholder needs to a high standard.
- Identifies existing issues preventing project delays and cost increase.
- Ensures cost-effectiveness in software project development
- Ensures software is delivered in time and within budget.
Challenges of Requirements Engineering
- Time-consuming and costly if requirements gathering isn't accurately managed.
- Difficulty ensuring clarity, consistency, and completeness.
- Conflicts between stakeholders, which can be hard to resolve.
- Making all stakeholders agree on requirements may prove to be challenging.
