Extreme Programming (XP) is an adaptive, agile development paradigm.
an endeavor to take software development best practices and "push them to the
limit."
characteristics:
Takes proven industry best practices and focuses them tightly.
,Combines those best practices (in their most intense versions) in a novel approach
to deliver a result that is greater than the sum of its parts.
XP Core Values: ANSWER communication- documentation, verbal discussion
(open and frequent).
simple approaches to reinforce this notion and make it a normal manner of
designing systems.
Users should provide input on functionality and requirements; other developers
should provide comments on designs and code; and the client should provide
feedback on meeting a business need.
Courage- XP practices are intended to give developers the confidence to "do it
right."
XP Practices (12) - ANSWER planning focuses on quickly developing a basic plan
and improving it as details become evident.

Small releases mark the moment at which the new system can be handed over to
users for acceptance testing and even productive use.
The forty-hour week and coding standards establish the framework for how
developers should work.
, The XP system development approach has three levels: system (the outer ring),
release (the middle ring), and iteration (the inner ring).
occur once during each development project.
Scrum - ANSWER the goal of which is to be rapid, agile, and intense and to go the
full extent.
The primary focus is at the team level.
social engineering that focuses on individuals rather than procedures and discusses
how teams of engineers might collaborate to build software in a succession of short
mini-projects
Software is produced incrementally, and restrictions are imposed empirically—by
concentrating on tasks that can be completed.
Product backlog
The product backlog is a prioritized collection of user needs used to select work to
be done in a Scrum project.
