1. Check for self -interested biases
Is there any reason to suspect the person making the recommendation of errors motivated by self interest?
Review the proposal with extra care, especially for over optimism.

3. Check for groupthink
Were there dissenting opinions within the team? Were they explored adequately?
Solicit dissenting views, discretely if necessary.

Could the diagnosis be overly influenced by an analogy to a memorable success?
Ask for more analogies, and rigorously analyse their similarity to the current situation.

Are credible alternatives included along with the recommendation?
Request additional options.

If you had to make this decision again in a year's time, what information would you want, and can you get more of it now?
Use checklists of the data needed for each kind of decision.
7. Check for anchoring bias
Do you know where the numbers come from? Can there be unsubstantiated numbers, extrapolation from history, a motivation to use a certain anchor?
Reanchor with figures generated by other models, or benchmarks, and request new analysis

Have the team build a case taking the outside view, use war games
