Get the organization involved in continuous improvement processes by formally evaluating past performances, including mistakes, and identifying ways to make improvements. You can make this precess work for individuals in a team format so peer-to-peer knowledge sharing can also help the individuals.

The mistake is to be celebrated.

I absolutely agree with you – we should learn from others’ mistakes. It’s like preparing the team for not making mistakes or avoiding mistakes. And I think we try to do just that through all the structured training programs we do.   

However, mistakes are inevitable and we are looking to have a structure/process that helps us learn from them. Another important aspect I am trying to address is to have a work environment which allows everyone to feel ok when they make mistakes. When senior people share their failures, everyone else would be ok to share theirs too. 

Looks forward to your thoughts. 

I would rather encourage your organization to learn from others’ mistake or failure. Ample resources, in terms of case studies and papers, can be found on internet.
