The premortem – when an organisation has almost come to an important decision but hasn’t formally committed itself, the decision makers gather for a brief session.
They are asked to imagine that it is one year later and that the idea has been a complete disaster.
They then have to write a short history of what happened.
The premortem can prevent many a disaster.
By contrast, a postmortem is always too late.
It’s all about timing.
