Not losing face is so important to us that we often even help our enemies to avoid it.
Any change carries with it an implicit threat that those who designed or practiced the past must be wrong and therefore lose face. Therefore it is vital to make it safe for people to change and give up the past.
In other words when people attempt to practice or think in the new ways there should be only praise and no punishment. Experiments may go wrong but the good intent must be honoured
Do the leaders in your organisation maintain face by changing or not changing?
How can you make it safe to change?
