Study Notes
Chapter 3 - Agile Software Development
- Rapid software development is becoming increasingly important as businesses operate in fast-changing environments.
- Agile methods, such as Extreme Programming (XP), are used to quickly respond to changing business needs.
- Agile development involves rapid and flexible response to change, with an emphasis on delivering working software in short iterations.
Agile Methods
- Agile methods prioritize individuals and interactions, working software, customer collaboration, and responding to change.
- Agile manifesto: "We value individuals and interactions over processes and tools, working software over comprehensive documentation, customer collaboration over contract negotiation, and responding to change over following a plan."
Principles of Agile Methods
- Customer involvement: Customers are closely involved throughout the development process to provide and prioritize new system requirements and evaluate iterations.
- Incremental delivery: Software is developed in increments, with customers specifying requirements for each increment.
- People not process: Team members are left to develop their own ways of working without prescriptive processes.
- Embrace change: Expect system requirements to change, and design the system to accommodate these changes.
- Maintain simplicity: Focus on simplicity in both the software and the development process.
Agile Method Applicability
- Agile methods are suitable for:
- Product development where a software company is developing a small or medium-sized product for sale.
- Custom system development within an organization where there is a clear commitment from the customer to become involved in the development process.
Extreme Programming (XP)
- XP is an agile method that integrates good programming practices, such as:
- Incremental planning: Requirements are recorded on story cards, and the stories to be included in a release are determined by the time available and their relative priority.
- Small releases: The minimal useful set of functionality that provides business value is developed first, with frequent releases that incrementally add functionality.
- Simple design: Enough design is carried out to meet current requirements, and no more.
- Test-first development: Automated unit tests are written for new functionality before that functionality is implemented.
- Refactoring: Code is continuously refactored to keep it simple and maintainable.
XP Practices
- Refactoring: Making small, incremental changes to the code to improve its structure and simplicity while preserving its functionality.
- Pair programming: Programmers work in pairs, with each pair working together at the same workstation to develop the software.
Scrum
- Scrum is a general agile method that focuses on managing iterative development rather than specific agile practices.
- Scrum involves an outline planning phase, a series of sprint cycles, and a project closure phase.
- Sprints are fixed-length (usually 2-4 weeks) and correspond to the development of a release of the system.
Scaling Agile Methods
- Scaling up: Using agile methods for developing large software systems that cannot be developed by a small team.
- Scaling out: Introducing agile methods across a large organization with many years of software development experience.
- Scaling agile methods involves maintaining agile fundamentals, such as flexible planning, frequent system releases, continuous integration, test-driven development, and good team communications.
