    Study Notes

    Software Process Models

    • A software process model is a simplified representation of the software development process.
    • A software process model defines the activities, actions, and tasks involved in the software development process.

    Software Process Activities

    • Defining what the system should do is known as requirements analysis.
    • Validation refers to the process of checking that the system does what the customer wants.
    • Evolution refers to the process of changing the system after its initial deployment.

    Common Features of Software Process Models

    • A common feature of all software processes is that they involve a series of activities, actions, and tasks.

    Process Activity Outcomes

    • The outcomes of a process activity are the products, deliverables, or artifacts produced during the activity.

    Software Process Model Types

    • The waterfall model is a plan-driven model with separate and distinct phases of specification and development.
    • The main drawback of the waterfall model is that it is inflexible and does not allow for changes to be made once the development process has begun.
    • Incremental development processes have planning that is incremental and easier to change to reflect changing customer requirements.
    • The main benefit of incremental development is that it allows for early delivery of a partial system and for customer feedback.

    Waterfall Model

    • The separate identified phases in the waterfall model are requirements analysis, design, implementation, testing, and deployment.

    Practical Processes

    • Most practical processes are a combination of different process models and do not conform to a single process model.

    Large Systems Engineering Projects

    • The waterfall model is mostly used for large systems engineering projects because it is a plan-driven model that allows for a clear understanding of the scope of the project and the tasks involved.

    Component-Based Development

    • The component-based development process involves assembling the system from existing components.

    Process Roles

    • Roles reflect the responsibilities and skills of the people involved in the process.
