Study Notes
Agile Methods
- Focus on providing fast and flexible software, adapting to changing requirements to reduce development costs
- Emphasize individuals and interactions, working software, customer collaboration, and responding to change over processes and tools, comprehensive documentation, contract negotiation, and following a plan
- Agile methods prioritize incremental delivery, customer involvement, and simplicity
Agile Principles
- Customer involvement: customers provide new system requirements and prioritize them
- Incremental delivery: software is developed in increments, with customer-determined requirements
- People not process: emphasize individual interactions and teamwork
- Embrace change and maintain simplicity
Agile Method Applicability
- Suitable for small to medium-sized software development companies
- Often used in companies with customer involvement and minimal external constraints
Extreme Programming (XP)
- Developed in the late 1990s, an effective agile method focusing on iterative development
- New releases are created frequently (daily or weekly)
- Customers receive increments every 2 weeks
- All tests are run for each build, and only successful builds are accepted
Extreme Programming Practices
- Incremental planning
- Small releases
- Simple design
- Test-first development
- Refactoring
- Pair programming: collaborative development with mutual code review
- Collective ownership: all developers are responsible for the entire system code
- Continuous integration: completed work is continuously integrated and tested
- Sustainable pace: no overtime, with on-site customer availability and requirements
XP and Agile Principles
- Support for iterative development with frequent small releases
- Customer continuous interaction with the development team
- Emphasis on people, with principles like pair programming, collective ownership, and avoiding overtime
- Change is supported with regular system releases
- Code simplicity is maintained through continuous refactoring
