Almost everything we’re trying to do in Agile coaching is behaviour change and most of the behaviours we’re trying to change are operating at an unconscious level ("System 1" in Daniel Kahneman’s Thinking Fast and Slow).
There are some simple cases where rationally deciding to change is enough to get that new behaviour although that's rarely adequate. Ask as smoker or a gambler why they haven't quit when all the logic says they should. Changing unconscious behaviour requires more than just a logical decision.
The very best trainings are experiential, not a series of lectures, and the agile community has jumped on these. From "back of the room" trainings to LEGO® Serious Play®, pair programming to clean language. Many of the very best Agile techniques are so effective because we're setting up conditions to leverage unconscious behaviour and yet we rarely recognize that fact. We've found something that works and often don't dig deeper to find out why it works or how we could tweak it to make it even better.
On this site and the associated training classes, we’ll look into the foundational skills for unconscious behaviour change. Taking from practical neuroscience, psychology, neurolinguistic programming, hypnosis, body language and other domains, we’ll give you a mix of theory and practical tips to elevate your skills.
