More frequently poor decisions are the result of a combination of Mistakes in the decision process Bounded rationality Suboptimization Causes of Poor Decisions LO 5s.2 4 Errors in the Decision Process Failure to recognize the importance of each step Skipping a step Failure to complete a step before jumping to the next step Failure to admit mistakes Inability to make a decision Mistakes in the Decision Process LO 5s.2 5 There are three general environment categories: Certainty Environment in which relevant parameters have known values Risk Environment in which certain future events have probabilistic outcomes Uncertainty Environment in which it is impossible to assess the likelihood of various possible future events Decision Environments LO 5s.3 6 Decisions are sometimes made under complete uncertainty: No information is available on how likely the various states of nature are. Decision Criteria: Maximin Choose the alternative with the best of the .
