    Study Notes

    Software Processes

    • Software processes are the activities involved in creating software systems
    • Software process models are abstract representations of these activities
    • General process models outline the structure of software development
    • Examples include the waterfall, incremental, and reuse-oriented models

    General Process Models

    • Waterfall model: Sequential phases with strict dependencies. Requirements, design, implementation, testing, and maintenance occur sequentially. Difficult to accommodate change.
    • Incremental development: Development and validation are interleaved, delivering parts of the system. Easier to incorporate changes and get feedback.
    • Reuse-oriented development: Assembles systems from pre-existing components or commercial-off-the-shelf systems (COTS). Reduces development time but may compromise requirements. Examples include stand-alone applications, objects integrated via frameworks (like .NET or J2EE), and Web services. Reuse has significant benefits for building business systems.

    Key Process Stages

    • Requirements Specification: Defining the services and constraints for the system's operation and development.

    • Requirements Engineering: Process of eliciting, analyzing, specifying, validating requirements

      • Stakeholders' desired system features

    • Software Design and Implementation: Converting the system specification into an executable system

      • Software design: creating the software structure to match the specification
      • Implementation: translating the design into working code

    • Software Validation: Ensuring the system conforms to its specification and meets user needs.

    • System and Component Testing: Testing individual parts, then testing the entire system

    • Customer Testing: Evaluating usability and satisfaction with user-provided data/scenarios.

    • Software Evolution: Adapting the software to changing requirements

      • System evolution: iterative process involving assessing the current system, proposing and implementing changes.

    Coping with Change

    • Change is unavoidable in software projects because of:
    • Changes in business needs, technological advancements, or platform modifications.
    • Methods to aid in adapting to change include:
    • Change anticipation and tolerance: Building flexibility into the process to facilitate easier changes.

    Prototype Development

    • A prototype is an initial version of a system, used to:
    • Demonstrate concepts and try out design options.
    • Help with requirements elicitation and validation.
    • Support exploration of design options and UI design in the design process.
    • Support back-to-back testing in the testing process.
    • Benefits include:
    • Improved system usability
    • Closer alignment to real user needs
    • Improved design and maintainability
    • Reduced development time
    • Types of prototypes include throw-away prototypes.

    Incremental Delivery

    • Systems are developed in increments from smaller parts to larger, more complete systems
    • User requirements are prioritized, with highest priorities included first.
    • Requirements are typically frozen once a component is started allowing further evolution for subsequent features.

    Process Improvement

    • Improving processes for quality, reduce costs, or speed up development time
    • Approaches to process improvement include:
    • Process maturity approach: Improving process management techniques and software engineering principles
    • Agile approach: Facilitating rapid, iterative development in response to changing needs.

    Process Metrics

    • Metrics for assessing process performance, often quantitative (e.g., time taken for activities, resources used, number of errors)
    • Capability Maturity Model (CMM): A framework for evaluating and improving software development processes. The CMM has different levels from "Initial" to "Optimizing," signifying the level of process maturity within an organization.
