The practice of Test-First Programming follows the path of: Write failing automated test -> Run failing test -> develop code to make test pass -> run test -> repeat. 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. This allows the PO to support the team effectively during Iteration Execution by answering questions, providing more detail on the functionality under development, and reviewing and accepting the completed Stories into the baseline. Below are the descriptions of the practices as described in the second edition of Extreme Programming Explained Embrace Change. Extreme Programming (XP): Also known as XP, Extreme Programming is a type of software development intended to improve quality and responsiveness to evolving customer requirements. Simplicity also means address only the requirements that you know about; don’t try to predict the future. XP (Extreme Programming) - Tracker, Customer, Programmer, Coach, Manager, Tester.

Extreme Programming Practices XP suggests using 12 practices while developing software. Extreme Programming emphasizes continuous and constant communication among the team members, managers and the customer. The team then breaks those stories into tasks to be completed within that week.

Next, the entire team gets together to create a release plan that everyone feels is reasonable. Programmers appreciate each other’s project input, deliver software quickly because they can distinguish relevant tasks from unnecessary ones. ScrumXP is a lightweight process to deliver value for cross-functional, self-organized teams within SAFe. Most SAFe teams apply Scrum with XP (see SAFe ScrumXP) as the basic framework. The development team works closely with customers, continuously planning, testing and providing feedback to developers, to quickly deliver valuable software.

The practice of Incremental Design suggests that you do a little bit of work up front to understand the proper breadth-wise perspective of the system design, and then dive into the details of a particular aspect of that design when you deliver specific features. They help educate the team in Scrum, Extreme Programming (XP), Kanban, and SAFe, ensuring that the agreed Agile process is being followed. Energized work means taking steps to make sure you are able physically and mentally to get into a focused state. During execution, the team builds and tests stories with the goal of delivering one or two every few days. ScrumXP details the two essential characteristics of Team and Technical Agility, with Scrum providing guidance for team agility and XP for technical practices. The code base is also designed to test run in ten minutes or less. Extreme Programming (XP) is a software engineering methodology, the most prominent of several agile software development methodologies. This practice encourages your team to automate your build process so that you are more likely to do it on a regular basis and to use that automated build process to run all of your tests. Like other agile methodologies, Extreme Programming differs from traditional methodologies primarily in placing a higher value on adaptability than on predictability.

These … Here are four most common roles associated with Extreme Programming: The Customer role is responsible for making all of the business decisions regarding the project including: The XP Customer is expected to be actively engaged on the project and ideally becomes part of the team. Easy keypad programming allows for code changes, additions, and deletions. A cross functional group of people with the necessary roles for a product form a single team. To address this, SAFe Agile teams operate within an ART, which provides mission alignment and a collaborative environment in which teams can cooperate with other teams to build the larger solution capabilities. Planning is done during release planning and iteration planning. It actually preceded Agile and led to Agile. The Extreme Programming practices, such as unit testing, pair programming, simple designs, common metaphors, collective ownership and customer feedback focus on the value of communication. They are intended to ensure conformance to standards, and more importantly, intended to ensure that the code is clear, efficient, works, and has QWAN. Scrum is a lightweight team-based process framework that fosters quick, iterative advancement of the solution. Key metrics that your team may track include velocity, reasons for changes to velocity, amount of overtime worked, and passing and failing tests.

Depending on which source you read, there is either no guidance, or there is a description of how roles typically found in more traditional projects behave on Extreme Programming projects. This is often one of the developers who spends part of their time each week filling this extra role. It actually preceded Agile and led to Agile. (The Agile Workspaces article provides more information on creating appropriate environments to support successful communication). (Choose three.) The reasoning behind that approach is that if you experience problems every time you integrate code, and it takes a while to find where the problems are, perhaps you should integrate more often so that if there are problems, they are much easier to find because there are fewer changes incorporated into the build.

XP’s primary contribution to the software development world is an interdependent collection of engineering practices that teams can use to be more effective and produce higher quality code. Some teams also apply WIP limits to some steps to create a ‘pull’ process within the iteration and to continuously balance the work against their available capacity, in order to increase throughput.
