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.
