Query: Radical ideas!

Kent Beck explores some interesting ways of improving the software development cycle. If you are not interested in some big changes, then this book is not for you.One of the more intersting concepts that Kent is pushing is this book is the concept of programming in pairs. This means that whenever code is written that you have 2 people working on the same computer to write code. My first thought was that this would slow down the process, but Kent explains that it does not actually slow down the process, and it actually speeds things up.This book contains many radical ideas that would really change the development process. For instance Kent explains that its better to meet the requirements as they exist at the end of the project, rather than the requirements that have been set at the begining of the project.In a day time when progress is measured in "internet time" and requirements are constantly changing, Extreme Programming provides some usefull ideas.
