Law of Demeter | Guided Learning Hour

This is a Guided Learning Hour. It is designed to be done together with your development team, although you can watch for yourself too.

The content is designed to promote a team discussion about good software design principles, and coupling in particular. The video includes a refactoring demo where I sort out a coupling problem and end with code that better follows the Law of Demeter. I also encourage you to try out the same exercise and improve your refactoring skills.

The last part of the video is a "facilitator's briefing". Watch this part to help you prepare to lead this session with your team. You can also find out more in my "Guided Learning Hour: How-to" video. The idea is that any technical coach or developer with an interest and some facilitation skills should be able to lead this session with their team, with a little preparation. It could be a good way to promote new ways of working in your team and be a step on the road towards Continuous Delivery.
