Extreme programming (XP) is a software development methodology intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development, [1] [2] [3] it advocates frequent releases in short development cycles, intended to improve productivity and introduce checkpoints at which new customer requirements can be adopted.
Extreme programming (XP) is an agile software development methodology used to implement software systems. This article details the practices used in this methodology. Extreme programming has 12 practices, grouped into four areas, derived from the best practices of software engineering. [1]
Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming. A life-cycle "model" is sometimes considered a more general term for a category of methodologies and a software development "process" is a particular instance as adopted by a ...
A software development methodology is a framework that is used to structure, plan, and control the life cycle of a software product. Common methodologies include waterfall, prototyping, iterative and incremental development, spiral development, agile software development, rapid application development, and extreme programming.
The waterfall model is the earliest Systems Development Life Cycle ... (a sentiment similar to that of extreme programming). ...
The extreme approach, conversely, does not run constantly, instead adapting the project activity during the process, which leads in the final stage to a desired result. [3] An extreme project management life cycle model is one that proceeds from phase to phase based on very limited knowledge of goal and solution.
Unit testing is the cornerstone of extreme programming, which relies on an automated unit testing framework. This automated unit testing framework can be either third party, e.g., xUnit, or created within the development group. Extreme programming uses the creation of unit tests for test-driven development. The developer writes a unit test that ...
These include (but are not limited to) scrum, extreme programming (XP), disciplined agile delivery (DAD), and rational unified process (RUP). Like DSDM, these share the following characteristics: They all prioritise requirements and work though them iteratively, building a system or product in increments. They are tool-independent frameworks.
