Some of the greatest info I've seen on creating a healthy engineering courtesy of Spotify:

• 0:50 - "We aim to make mistakes faster than anyone else" - Fail Fast and Improve Fast.
• 1:30 - "Fail Friendly Environment" - Encourage sharing of failures so everyone can learn from them. Some teams have "Fail walls" showing off their failures.

Tom Chi - Learning Through Prototyping

()[https://www.youtube.com/watch?v=kuqgrvUPc5g]
