If you are looking to fix a problem you might be looking the wrong way
How often have you heard – as I did on the TV news last night – “We need to understand the causes before moving forward…”, or some such nonsense?
Reasons and solutions are unconnected. Ferreting about for explanations is a worthy pastime if you are a ferret, but a waste of time if you are a person of action.
Once you have solved the problem, planned the way forward, and agreed who-does-what, there will be plenty of time to learn from the past so that you can avoid repeating your mistakes (and to recriminate and blame if you really must).
