This document outlines Martin Cronjé's talk on establishing a craftsmanship culture in a team. The talk discusses how software development is becoming more like a craft, and the need to grow people through deliberate practice and learning by doing. It suggests creating space regularly for coding practice sessions, with a focus on collaboration, learning new techniques, and experimenting. Getting feedback and reflecting on what works and doesn't work is important to constantly improve and make the learning opportunities last.

That may sound obvious, but most of us don’t do it in the activities we think of as practice.” It’s repeated a lot. “High repetition is the most important difference between deliberate practice of a task and performing the task for real, when it counts.” Feedback on results is continuously available. “You may think that your rehearsal of a job interview was flawless, but your opinion isn’t what counts.” It’s highly demanding mentally. “Deliberate practice is above all an effort of focus and concentration. That is what makes it ‘deliberate,’ as distinct from the mindless playing of scales or hitting of tennis balls that most people engage in.” It’s hard. “Doing things we know how to do well is enjoyable, and that’s exactly the opposite of what deliberate practice demands.” It requires (good) goals. “The best performers set goals that are not about the outcome but rather about the process of reaching the outcome.” You must be motivated to attend to the task and exert effort to improve your performance. The design of the task should take into account your pre-existing knowledge so that the task can be correctly understood after a brief period of instruction. You should receive immediate informative feedback and knowledge of results of your performance. You should repeatedly perform the same or similar tasks.
- How do we fix the problem?
- This was a particular problem because RESULTS is one of our values at MYOB and we measure progress towards our goals primarily as either GREEN, on target, or RED, behind target. Our challenge was to remove the RED. We weren’t living up to our values: Our values define what makes us different to other organisations and we pride ourselves on living our values.
