    Study Notes

    Software Processes

    • Software development is a process of interleaved sequences of technical, collaborative, and managerial activities. This means the process is not linear but iterative, with multiple activities happening simultaneously.
    • The four basic process activities are specification, development (design and implementation), validation (Testing), and evolution. Each activity plays a critical role in building and maintaining software.

    Specification

    • The software specification process defines what features the system should have. This includes outlining services, constraints, and expectations from the system.
    • The requirements engineering process is a key part of specification. It involves eliciting and analyzing user needs, specifying those needs in detail, and validating their accuracy and completeness.
    • Stakeholders are individuals or organizations affected by the system. They have a legitimate interest in the software and their needs must be considered during the specification process.

    Development

    • Development converts the system specification into a working system. This involves design and implementation.
    • Design focuses on creating the overall structure and components of the system. It involves architectural design to map out the system's structure, database design to define data structures, interface design to define communication between components, and component selection and design to choose or create reusable components.
    • Implementation translates the software design into an executable program. This involves coding in a suitable programming language.

    Validation (Testing)

    • Validation aims to ensure the system conforms to its specifications and user requirements. It includes verification and validation (V&V), which involves reviewing and testing the software throughout the development lifecycle.
    • System testing is the most common validation activity. This involves executing the system with test cases derived from the specification and real data.
    • System testing involves various stages, including:
      • Component testing: Individual components are tested independently.
      • System testing: The system as a whole is tested. This is important to test emergent properties, which are unexpected behaviors that arise due to the interaction between multiple components.
      • Customer testing: Testing with customer data ensures the system meets the customer's needs.

    Evolution

    • Software is inherently flexible and can change. As requirements change, the software that supports them must adapt.
    • Evolution is an ongoing process of modifying and updating the software system. It involves adapting to changing business needs, fixing bugs, and enhancing features.

    Key facts

    • The four basic process activities are organized differently in various development processes. For example, the waterfall model organizes these activities in sequence, while incremental development interleaves them.
    • Software development is a continuous cycle. It involves ongoing development and evolution as the requirements change.
