Advice
Ensure psychological safety as broadly as possible, so that people/the team feel free to fail. Of course the important part is to learn from it.
Incorporate fun with a Fail Wall...or the like (somewhere to document the fail, the lesson and any next attempts/actions etc.). So that people talk freely about them and normalize not only talking about the fail "You'll never guess that I just did" 🤣, but also the lesson "You'll never guess what i just learnt"💡.
Relevancy for today
As already mentioned in these "Tips & Lessons", change is a constant. So is failure, so is learning. As the saying goes, "if we don't learn to fail, then we fail to learn" …..we fail to change.
Changing/failing and learning as efficiently as possible have always been important, never more so than now.
