Study Notes

Software Engineering Overview

Software Engineering involves designing, developing, testing, and maintaining software systematically to create high-quality and reliable systems.
Primarily applied to large software projects rather than individual applications.

Characteristics of Software

Intangible: Software cannot be physically touched or seen.
Replicable: Easy to copy and distribute.
Complexity: Understanding and modifying large systems can be challenging.
Adaptability: Software must evolve based on changing user needs.

Key Components of Software

Functionality: Features like data storage, processing, user interfaces, communication, and security.
Reliability: Ability to perform intended functions consistently; relies on accurate coding and thorough testing.
Efficiency: Optimal use of system resources such as memory and bandwidth, minimizing latency.
Usability: Ease of use; low learning curve required for new users.
Maintainability: Ease of making modifications to improve functionality or fix errors.
Portability: Ability to move software between environments with minimal changes.

Applications of Software

System Software
Real-time Software
Business Software
Engineering and Scientific Software
Embedded Software
Personal Computer Software
Web-Based Software
Artificial Intelligence Software

Layered Technology in Software Engineering

Comprised of interconnected layers including:
- Quality Focus: Continuous improvement principles, security, maintainability, and usability.
- Process: Foundation capturing all activities for timely software development.
- Method: Addresses “how-to-do” questions across various tasks.
- Tools: Enable integration and usage of information across processes.

Generic View of Software Engineering

Definition Phase:
- Requirements gathering, feasibility study, specification documentation (e.g., SRS).
Development Phase:
- System design, coding implementation, and rigorous testing.
Maintenance Phase:
- Includes corrective, adaptive, perfective, and preventive maintenance.

Software Process Models

Waterfall Model:
- Linear and sequential approach; phases must be completed before moving forward, with no overlap.
- Phases: Requirements, Design, Development, Testing, Deployment, Maintenance.
- Advantages: Simple, clear milestones, strong documentation.
- Disadvantages: Inflexible to changes and potential late testing issues.
Incremental Model:
- Develops software in small, manageable increments, allowing continuous feedback and adaptation.
- Phases include communication, planning, modeling, construction, and deployment.
- Advantages: Flexible, less expensive changes, easier testing.
- Disadvantages: Ongoing management effort, higher overall costs.

Evolutionary Process Models

Designed for accommodating changes; includes:
- Prototype Model: Initial prototypes guide development, with user feedback gathered for revisions.
- Spiral Model: Iterative approach with risk management at each phase. Each spiral loop includes objectives, risk resolution, development, and review.
- Concurrent Development Model: Parallel activities across phases, allowing simultaneous progress and adaptation to changes.

Agile Development

Emphasizes iterative development, customer feedback, and flexibility in changing requirements.
Key principles include customer satisfaction, frequent delivery, collaboration, and face-to-face communication.

Characteristics of Agility

Flexibility to adapt, rapid software delivery, continuous customer involvement, strong collaboration, and ongoing process improvements.

Agile Process Model

Combines iterative and incremental approaches for quicker adaptation during development processes.

Extreme Programming (XP)

Focuses on technical excellence and rapid development with core values including communication, simplicity, feedback, courage, and respect.
Life Cycle of XP: Includes planning, coding, testing, and frequent iterations for refinement based on user feedback.### User Stories and Definitions
Clients outline their needs through brief descriptions known as user stories.
Effort for each user story is estimated by the team, which schedules releases based on priority and effort.

Design Phase

Essential design is only created for current user stories.
A common analogy or story helps the team understand system architecture clearly.

Coding Phase

Pair programming is promoted, where two developers collaborate at one workstation to improve code quality.
Test-Driven Development (TDD) is practiced by writing tests before the actual code to ensure functionality.

Testing Phase

Emphasis is placed on testing, including both automated unit tests and customer-led acceptance tests.
Unit tests verify specific features, while acceptance tests determine if the overall system meets requirements.

Listening Phase

Regular customer feedback is gathered to ensure the product meets needs and adapts to changes.

Key Practices of Extreme Programming

Pair Programming: Enhances code quality and knowledge sharing through collaboration at one workstation.
Test-Driven Development (TDD): Ensures code is verified through tests written prior to coding.
Refactoring: Continuously improves the codebase without altering functionality, focusing on simplifying code and enhancing maintainability.

Agile Process Models

Scrum

A management framework allowing teams to self-organize and tackle complex problems effectively.
Features include lightweight structure, self-organization, simplicity, and enhanced teamwork.
Lifecycle of Scrum:
- Sprint: A time-boxed period (one month or less) where a new sprint starts immediately after the previous one.
- Release: Final stage when the product is deemed complete.
- Sprint Review: Evaluates features that may not be achievable and leads to the Sprint Retrospective.
- Sprint Retrospective: Assesses product quality or status.
- Sprint Backlog: Comprises features assigned to sprints along with sprint planning.

Kanban

Visualizes workflow while limiting work in progress to streamline the work process.
Focuses on continuous delivery, allowing features to be released as they are ready.

Lean Software Development

Prioritizes customer value delivery, waste elimination, and continuous improvement.
Encourages collaboration with customers, shortened feedback loops, and team empowerment.

Crystal

Customizes methodology based on specific project, team, and organization characteristics.
Offers various "colors" or variants (e.g., Clear, Yellow, Orange) tailored to different project types.

Dynamic Systems Development Method (DSDM)

An Agile framework ensuring project delivery is on time and within budget without compromising quality.
Specific roles are defined, including Executive Sponsor, Project Manager, and Solution Developer.

Feature-Driven Development (FDD)

An iterative and incremental process focusing on feature design and domain object modeling.

Tools for Agile Development

Various tools enhance collaboration, project management, and continuous integration:
- JIRA: Supports Agile project management, including Scrum and Kanban boards and backlog management.
- Trello: Organizes tasks through visual boards, lists, and cards.
- Asana: Aids teams in tracking, managing, and organizing their work.
- Azure DevOps: Provides a set of development tools for version control and project tracking.
- GitHub: Facilitates version control and collaboration, supporting Git repositories and code reviews.
- Slack: Enhances team communication with real-time messaging and file sharing.
