Extreme Programming

Extreme Programming (XP) is a software development methodology which is intended to improve software quality and responsiveness to changing customer requirements. In Extreme Programming (XP) iteration period would be less than in scrum, which is being 2-4 weeks.

The developer priorities what to do first on the basis of client requirement. This duration which was being fixed for iteration, can be increase if the some development part is still pending. The build would deployed with having all the client needs. Thus iteration period is not fixed here it can be increase, but iteration should meets all the client's requirement in this build. More attention is required for testing in XP.

Extreme Programmers work together in pairs and as a group, with simple design and obsessively tested code, improving the design continually to keep it always just right for the current needs.
