    Study Notes

    Course Objectives

    • The CSC2101 module aims to provide students with theoretical knowledge of software engineering and the software development life cycle (SDLC), with a focus on agile/scrum processes, UML modelling, software architecture, refactoring, version control, continuous integration, and continuous development.

    • The course also emphasizes practicing SDLC knowledge in a team project, conducting software development for industry customers within the team project utilizing the Agile Scrum framework.

    PSD & TP 1 and PSD & TP 2 Structure

    • CSC2101 – PSD & TP1 is taught over trimester 1, module lead is Dr. Cao Qi.
    • CSC2102 – PSD & TP2 is taught over trimester 2, module lead is Dr Peter Yau.
    • Each module carries six credits.
    • Theory and practical aspects of the modules are closely intertwined, students will work on software development projects as a team.

    Course Schedule

    • Lectures are held every Friday, 9:00 – 11:00 am, via Zoom.
    • Tutorials are conducted in person (F2F) on Fridays, 2:00 – 3:00 pm in weeks 2, 4, 5, 6, 9, 10, 11, and are optional.
    • Weeks 1 – 6 will involve self-learning on GitHub which will consist of seven videos.
    • Team project activities will be held with customer companies (F2F) on various days and times specified in the TP materials.

    Assessment Breakdown

    • PSD Quiz 1 accounts for 25% of the final grade and will be held in week 6.
    • PSD Quiz 2 accounts for 30% of the final grade and will be held in week 13.
    • Weekly pop quizzes and class participation contribute 5% of the final grade and will be assessed throughout weeks 1-12.
    • Team project activities account for 40% of the final grade and will be broken down and scheduled according to the TP materials.

    Good Software Attributes

    • Maintainability: The ability to expand, reuse, and adapt software without becoming obsolete.
    • Dependability and Security: Software functions reliably without causing damage in case of failure, preventing malicious users from compromising system integrity or data.
    • Efficiency: Optimal use of resources such as processing time, memory, responsiveness, and power consumption.
    • Reliability: Indicates the frequency of software functioning as expected.

    Software Development Life Cycle

    • Software is more than just computer programs, it includes associated documentation, libraries, support websites, and configuration data.
    • Software development involves distinct phases:
      • Software Specification: Defining the purpose, functionality, and constraints of the software.
      • Software Development: Actual coding and implementation of the software based on specifications.
      • Software Validation: Thorough testing and verification to ensure software meets requirements, quality standards, and security protocols.
      • Software Evolution: Continuous adaptation, enhancements, and bug fixing throughout the product lifecycle.

    Software Cost

    • Software frequently constitutes the majority of costs in computer systems projects.
    • Software costs for personal computers (PCs) often exceed hardware costs.
    • Software maintenance typically becomes more expensive than development over time.
    • For systems with an extended lifespan, maintenance costs can significantly surpass initial development costs.

    Software Development Life Cycle (SDLC) Cost Estimation

    • The different stages of the SDLC contribute varying percentages to the overall cost.
    • Requirement Specification Phase: 3%
    • Analysis & Design Phase: 8%
    • Implementation Phase: 7%
    • Testing Phase: 15%
    • Maintenance Phase: 67%

    Software Process Models

    • Software development strategies aim to streamline and optimize the software creation process.
    • The chosen strategy depends on project constraints, available resources, and team expertise.
    • Several models can be combined within a single software project to address various needs.

    Waterfall Model

    • This model follows a linear, sequential approach to software development.
    • Each phase must be completed before moving to the next, with minimal feedback loops.
    • Suitable projects:
      • Well-defined and stable requirements.
      • Adequate resources and team expertise.
      • Projects of moderate size and complexity.
      • No urgent need for specific project components.

    Incremental Model

    • This model breaks down the software into increments, delivered to users in a staged manner.
    • Each increment builds upon the previous one, adding features and functionality.
    • Suitable projects:
      • Requirements reasonably well-defined but subject to change.
      • Rapid delivery of basic software functionality.
      • Projects involving new technologies or with team members lacking extensive experience.

    Evolutionary Process Models

    • These models are designed for situations where software requirements evolve over time.
    • They emphasize flexibility and iterative development, adapting to user needs through continual improvements.
    • Common examples:
      • Prototyping Model
      • Spiral Model

    Prototyping Model

    • This model focuses on creating a working prototype quickly to gather user feedback and refine requirements.
    • Suitable projects:
      • Small or low-cost systems.
      • Unclear or incomplete requirements.
      • Projects with active customer involvement.
      • Teams lacking significant expertise.

    Spiral Model

    • This model combines elements of iterative and incremental development with risk analysis, allowing for early identification and mitigation of potential problems.
    • Suitable projects:
      • High-risk projects with frequent releases.
      • Large or complex systems with ambiguous requirements.

    Model Selection Example

    • A large system with reasonably well-defined requirements, except for a small, low-cost component.
    • The team possesses sufficient expertise for most aspects, but lacks experience for the small component.
    • Active customer involvement is required for the small component, and adequate resources are available.
    • The system is not considered highly complex.
    • Possible Proposal:
      • Develop the system using an incremental model, adding features incrementally.
      • The small component lacking team expertise will be treated as a separate increment.
      • The waterfall model will be utilized within each increment.
      • The small, specialized component will be developed using a prototyping model.
