NOW

In our daily lives, many events take place. To any such event our 1st reaction will be to cross-question just like reporters on tv. For example: 

Why & How it happened?

Who did it?

Basically go in to Root cause analysis mode.

Once we are done with this line of questioning, we go to next line of thought which is future centric.

How to prevent this from happening in future?

What steps we shall take in future in case this problem arises?

By no means, I'm against this approach as it provides required insight however 1st response shall be 'How to manage situation at hand without fixing blame/ identifying responsible?'

There will be ample amount of time to do RCA and Due Diligence.

Focus on problem at hand. Focus on NOW. Rest all will fall into place.
