Your decision-making matrix is made up of combinations of two fundamental styles. Tell me about the first: how people use information.

Brousseau: Some people grab the most pertinent facts and make their decision. They know there may be more information, but they feel that the information at hand is sufficient. Other people want to be sure they haven't missed important details that may change their understanding. So they hold out [until] their efforts to uncover new information aren't turning up anything very new.

The other fundamental style involves how people create options.

Brousseau: Some people zero in on one option they see as the best for the situation. Once they do this, they stick with that course of action. Others come up with numerous options. No one course of action seems adequate, so they put several into effect, and they may modify their course along the way as things change.
