    Study Notes

    Non-Functional Requirements

    • Non-functional requirements constrain the system being developed and the development process.
    • They relate to the emergent properties of the system and apply to the system as a whole.

    Requirements Engineering

    • Requirements engineering involves three key activities:
      • Elicitation and analysis
      • Specification
      • Validation
    • Requirements engineering is the process of determining, documenting, and maintaining the requirements.

    Software Requirements Document

    • The software requirements document (SRS) is an agreed statement of the system requirements.
    • It should be organized so that both system customers and software developers can use it.
    • The document may include:
      • Product and process standards
      • System architecture
      • Functional and non-functional requirements
      • System models
      • System evolution
      • Appendices

    Agile Methods and Requirements

    • Many agile methods argue that producing a requirements document is a waste of time as requirements change quickly.
    • Agile methods use incremental requirements engineering and express requirements as user stories.

    Requirements Elicitation and Analysis

    • Requirements elicitation and analysis involves working with system stakeholders to find out about:
      • Application domain
      • System services
      • System performance
      • Hardware constraints
      • Other systems
    • Stages include:
      • Requirements discovery
      • Requirements classification and organization
      • Requirements prioritization and negotiation
      • Requirements specification

    Requirements Validation Techniques

    • Requirements validation is the process of checking the requirements for:
      • Validity
      • Consistency
      • Completeness
      • Realism
      • Verifiability
    • Techniques include:
      • Reviews
      • Prototyping
      • Modeling

    Requirements Management

    • Requirements management is the process of managing and controlling changes to the requirements.
    • It involves:
      • Change analysis and costing
      • Change implementation
      • Change tracking and reporting

    Changing Requirements

    • The business and technical environment of the system always changes after installation.
    • Changes can include:
      • New hardware
      • Interface with other systems
      • Business priorities
      • Legislation and regulations
    • Requirements change management involves:
      • Assessing the impact of the proposed change
      • Deciding whether to proceed with the requirements change
      • Modifying the requirements document and system design and implementation
