ShuHaRi
tags:
Shu-Ha-Ri is a way of thinking about how you learn a technique. The name comes from Aikido, and Alistair Cockburn introduced it as a way of thinking about learning techniques and methodologies for software development.
The idea is that a person passes through three stages of gaining knowledge:
- Shu: In this beginning stage the student follows the teachings of one master precisely. He concentrates on how to do the task, without worrying too much about the underlying theory. If there are multiple variations on how to do the task, he concentrates on just the one way his master teaches him.
- Ha: At this point the student begins to branch out. With the basic practices working he now starts to learn the underlying principles and theory behind the technique. He also starts learning from other masters and integrates that learning into his practice.
- Ri: Now the student isn't learning from other people, but from his own practice. He creates his own approaches and adapts what he's learned to his own particular circumstances.
