Extreme Programming is a discipline of software development based on values of simplicity, communication, feedback, courage, and respect. Encourages a common set of terms for the system, A quick and easy way to explain the system. Scope − How much of a problem must be solved for the system to be valuable in production? Facilitating continuous improvement to support higher quality and productivity, and better outcomes, it employs iterations—typically a two-week timebox—during which the team defines, builds, tests, and reviews results. As part of the ART, all teams plan, demo, and learn together, as illustrated in Figure 2, which avoids them focusing solely on local concerns. Extreme Programming is a new methodology designed to help small development teams deliver value despite constantly changing requirements. On-site customer 1.3. A user story includes which three things?
Each day, the team has a formal event—the daily stand-up (DSU)—to understand where they are, escalate problems, and get help from other team members. The result is a system that is capable of accepting change. The room may have separate workstations where the team members can work... Of the four basic practices of Extreme Programming (XP) it is the design phase that can be the most problematic. It prescribes two specialty roles: Scrum Master and Product Owner [2]. This review is planned once in every two or three weeks so the customer can easily steer the development. In this case, the simple storyboard above evolves into a more structured Kanban board. One cannot be certain of anything unless one has tested it. ), What are two behaviors of an effective Scrum Master? The 10 Minute Build also encourages developers to hit a rhythm and good stride when working on a product. The difference between this approach and more conventional system development methods is the focus on designing and coding for the needs of today instead of those of tomorrow, next week, or next month.
Related to the "communication" value, simplicity in design and coding should improve the (quality of) communication. During the meeting, youâll review your previous work and... Quarterly Cycle Amongst the twelve primary practices of XP comes Quarterly Cycle.
…a holistic or ‘rugby’ approach—where a team tries to go the distance as a unit, passing the ball back and forth—may better serve today’s competitive requirements.
As reality overtakes the plan, update the plan.

The 10-minute build practice is an extreme programming practice where the code base is designed by the developer to be built automatically. The code base is also designed to test run in ten minutes or less. The duration of the short cycle may vary with the software that needs to be built. When writing code, the unit test provides direct feedback as to how the system reacts to the changes one has made.
The five values are: Building software systems requires communicating system requirements to the developers of the system.
(Note: Scrum uses the term ‘sprint.’ SAFe uses the more general term ‘iteration.’). ScrumXP is a lightweight process to deliver value for cross-functional, self-organized teams within SAFe. All the builds or tests that are run in the 10-minute build must be followed up with continuous integration in agile.

The high discipline required by the original practices often went by the wayside, causing certain practices to be deprecated or left undone on individual sites. Within that constraint, they still tend to move business priorities earlier in the development, reducing the chance that important stories will have to be dropped towards the end of the development of a release due to time constraints. What are some other test cases that might not work yet? The principle of embracing change is about not working against changes but embracing them. The advantages of Continuous Integration are −. Prompts the developers to proactively improve the product as a whole, Increases the developer knowledge of the system.
