Implement XP engineering practices
XP practices provide valuable addition to agility when these practices are deployed along with other Agile methodologies like Scum, SAFe, Kanban, etc.
Some of popular XP practices:
- Simple system design: An emphasis was placed on designing only what was needed to support the functionality being implemented. In other words, do what the customer needs, as simply as possible, and nothing else. Take on a mindset to reduce complexity from the beginning.
- Refactoring: Refactoring is the process of improving the design of code without changing the functionality; the code should be clean and readable. Any duplication should be consolidated.
- Test Driven: Unit tests were written prior to the construction of code. This practice forces developers to understand the interface and expected functionality of a class. The tests accumulate over the duration of a project, providing a library of regressions tests.
- Pair programming: All code to be sent into production is created by two people working together at a single computer. Pair programming increases software quality without impacting time to deliver.
- Continuous integration: The latest code from each programmer mixed together is a difficult process, especially if this task is not done often. To stay resilient, after writing new code that passes all tests locally, programmers must then integrate their changes with the latest code base and ensure all the tests still pass. If not, fixes must be made right away until all tests again pass.
There are more XP practices (for example: Run Acceptance tests often, Planning Game, Metaphor, etc.) which teams can adopt for their projects.
