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]
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.
You aren't gonna need it" [1] [2] (YAGNI) [3] is a principle which arose from extreme programming (XP) that states a programmer should not add functionality until deemed necessary. [4] Other forms of the phrase include "You aren't going to need it" (YAGTNI) [ 5 ] [ 6 ] and "You ain't gonna need it".
A spike is a product development method originating from extreme programming that uses the simplest possible program to explore potential solutions. [1] It is used to determine how much work will be required to solve or work around a software issue.
The INVEST mnemonic for Agile software development projects was created by Bill Wake [1] as a reminder of the characteristics of a good quality Product Backlog Item (commonly written in user story format, but not required to be) or PBI for short.
This page compares software with specific support for the scrum framework. Although the features of some general project management software can be conceptualized around scrum, general project management software is not included on this list unless it has, or a plugin for it has, specific support for scrum.
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.
Kent Beck speaking in 2001. Kent Beck (born 1961) is an American software engineer and the creator of extreme programming, [1] a software development methodology that eschews rigid formal specification for a collaborative and iterative design process.
