A Pattern Language

"At the core... is the idea that people should design for themselves their own houses, streets and communities. This idea... comes simply from the observation that most of the wonderful places of the world were not made by architects but by the people".

Let’s see if there was no XP

Write thousands of lines of code without tests.

You cannot see the problems you made until the very end.

You debug your code on a printed copy.

Preparing a server usually takes a week at fastest.

You can only integrate at the end of the project.

When your real project starts :P

What is XP?

Extreme Programming (XP) is about social change.

Extreme Programming Explained: Emblace Change (2nd Edition) Kent Beck

Prepare for success.

Don’t protect yourself from success by holding back.

Do your best and then deal with the consequences.

That’s extreme.

You leave yourself exposed.


It is about letting go of habits and patterns that were adaptive in the past, but now get in the way off its doing our best work.

It is about giving up defenses that protect us but interfere with our productivity.

It may leave us feeling exposed.


Are you ready

to have yourself

exposed for success?

XP assumes:

you see yourself a part of a team

you want to work together

change can be made inexpensive

you want to grow to improve skills and to improve your relationships

you are willing to make changes to meet those goals

Expose yourself:

How extreme can you be

to deliver success to your customer, team and society?
