Making decisions when there is uncertainty is a different process than when you know the outcomes (certainty) or the expected range of outcomes for your machining business. decision making under risk to decision making with certainty –Build the large plant if you know for sure that a favorable market will prevail –Do nothing if you know for sure that an unfavorable market will prevail States of Nature Favorable Unfavorable Decision p = 0.5 p = 0.5 Large plant $200,000 -$180,000 Small plant $100,000 -$20,000 Medical decision making skills.
