How can the project process stop that 11th hour 'hold the presses' moment. My view is people don't spend enough thinking time reviewing the strategy and approving it with 100% belief.

It always amazes me that everything has gone well, approved gateways etc then just when you think it's in the bag along comes can we change that please.

As as answer to this, I am exploring the use of a customer model. So when someone asks the million dollar question, the constantly updated model can show that it's not important and been considered. This creates a new challenge of showing that you're : a. clever clogs, b. don't want to do the work or c. don't agree with the client.
