What is it?
Extreme Programming is a discipline of software development based on values of:
• simplicity • communication • feedback • Courage.
• Multiple short development cycles• Described as: flexible, agile

What is it? (continued…)
• March 6, 1996• One of several popular Agile Processes• Successful• Intended to improve software quality and
responsiveness

How it works!
• Stresses customer satisfaction– Instead of delivering
everything at once– Delivers the software
you need as you need it
• Extreme Programming EMPOWERS!– Allows developers to
confidently respond to changing customer requirements

Goals•Higher Quality, More Productively
•Reduce Cost of changes in requirements•Introduces:
• basic values,• principles • practices on top of the agile programming framework.
•Anticipate problems•Plan ahead.

4 Basic Activities
1. Coding
2. Testing
3. Listening
4. Designing
1. only truly important product of the system development process
2. Unit Tests and Acceptance tests.
3. Must listen to what the customers need the system to do
4. Good design will avoid lots of dependencies within a system

Rulesand Principles
• 29 rules are given in the categories of planning, managing, designing, coding, and testing. Planning, managing and designing are called out explicitly to counter claims that XP doesn't support those activities.
• Principles are intended to foster decisions in a system development project. The principles are intended to be more concrete than the values and more easily translated to guidance in a practical situation.
