    Study Notes

    Requirements Development Process Framework

    • The requirements development process is interwoven, incremental, and iterative, with progressive refinement of detail.
    • The process involves 7 initial steps and additional steps for each release or development iteration.
    • The process framework is flexible and can be adjusted for different projects.

    Requirements Analysis

    • Model the application environment using simple analysis models like context diagrams and ecosystem maps.
    • Create user interface and technical prototypes to clarify requirements and achieve mutual understanding.
    • Analyze requirement feasibility by evaluating the implementation cost, performance, and risks associated with each requirement.

    Requirements Elicitation

    • Define product vision and project scope to establish a common understanding of the product's outcome.
    • Identify user classes and their characteristics to avoid overlooking user needs.
    • Create user personas to represent particular user classes.
    • Select a product champion for each user class to serve as the literal voice of the customer.

    Software Development Life Cycles

    • Different life cycles allocate requirements effort across the product development period.
    • The total requirements effort may not vary significantly between projects, but the timing distribution of requirements work is different.
    • Examples of life cycles include the pure waterfall life cycle, which allocates most requirements development effort at the beginning of the project.
