Multiple Questions : Answering one :.

Extreme Programming and Scrum development :

Both the scrum and exretme programming are two agile software developments. This can be used together or independently. Both are having differences as well as similarities.Both the scrum and XP works in iterations but of different time durations. Iterations in scrums called sprints generally lasts from two weeks to 1 month while in the case of XP, iterations are shorts which lasts for one to two weeks.Scrum teams are not flexible enought to make changes in their sprints. Once the sprints are planned, scrums teams will not make any changes to the features and developments in the current sprint. But, in the XP we can make changes to the iterations even after it is planned for the feature that has not yet started. A new feature of equivalent size can be swapped into the iteration in exchange for the unstarted feature.In scrum , the team decides the sequence in which issues to be worked up on in a sprint. But in XP, they works with a strict priority order decided by the customer.Scrum doesn’t prescribe any engineering practices while the XP uses engineering practices, particularly things like test-driven development, the focus on automated testing, pair programming, simple design, refactoring, and so on.
