    Lec 4 Software Development Process

    Uploaded by

    A software process is a collection of activities, actions, and tasks used to create software work products. It establishes a framework including five key activities: communication, planning, modeling, construction, and deployment. The framework provides a foundation that applies to all software projects regardless of size or complexity. It also includes umbrella activities like tracking and quality assurance. However, the process should be adaptable to each project's specific needs rather than a rigid prescription. The level of activities, stakeholders' involvement, and team autonomy may differ between processes adopted for different projects.

    Software Development Process Models

    The Software Process
    • A process is a collection of activities, actions, and tasks that are
    performed when some work product is to be created.
    • An activity strives to achieve a broad objective (e.g.,
    communication with stakeholders)
    • An action (e.g., architectural design) encompasses a set of tasks
    that produce a major work product (e.g., an architectural model)
    • A task focuses on a small but well-defined objective (e.g.,
    conducting a unit test) that produces a tangible outcome.
    • A process is not a rigid prescription for how to build software.
    • Rather, it is an adaptable approach that enables the software team to pick
    and choose the appropriate set of work actions and tasks.
    • The intent is always to deliver quality software on time to satisfy both
    sponsors and users.
    The Process Framework

    • A process framework establishes the foundation for a complete software


    engineering process by identifying a small number of framework activities
    that apply to all software projects, regardless of their size or complexity.
    • In addition, the process framework encompasses a set of umbrella activities
    that are applicable across the entire software process.

    • Note: Umbrella activities include software project tracking and control, risk
    management, quality assurance, reusability management, etc.
    The Process Framework
    • A generic process framework for software engineering encompasses five
    activities:
    1. Communication. Before any technical work can start, it is critically important to
    communicate and collaborate with the customer (and other stakeholders).
    • The intent is to understand stakeholders’ objectives for the project and to gather requirements
    that help define software features and functions.
    2. Planning. It defines the technical tasks to be conducted, the likely risks, the required
    resources, the work products to be produced, and a work schedule.
    3. Modeling. In modeling, we create a “sketch” of the thing to understand what it will look
    like architecturally, how the parts fit together, etc.
    • A software engineer does the same thing by creating models to better understand software
    requirements and the design that will achieve those requirements.
    The Process Framework

    4. Construction. This activity combines code generation and the testing that is required
    to uncover errors in the code.
    5. Deployment. The software (as a complete entity or as a partially completed
    increment) is delivered to the customer, who evaluates the delivered product and
    provides feedback based on the evaluation.

    • These five generic framework activities can be used during the development
    of any software.
    • The details of the software process will be quite different in each case, but the
    framework activities remain the same.
    Process Adaptation
    • The software engineering process is not a rigid prescription that must be
    followed strictly by a software team.
    • Rather, it should be agile and adaptable (to the problem, to the project, to
    the team, and to the organizational culture).
    • Therefore, a process adopted for one project might be significantly different
    from a process adopted for another project.
    • Among the differences are:
    • Overall flow of activities, actions, and tasks
    • Manner in which quality assurance activities are applied
    • Degree to which the customer and other stakeholders are involved with the project
    • Level of autonomy given to the software team, etc.
