The “D” in the DECIDE model, is to deploy or act on the decision.
The final step or the “E” in the DECIDE model, is to evaluate the decision. The final phase brings the system full circle, as it asks the decision maker to evaluate the decision-making process and to apply feedback to both the system and to the decision problem for future reference.
An appropriate decision analysis should include, but not be limited to questions such as, was the problem properly framed? Was all relevant information taken into account? Was there an appropriate range of alternatives? Were personal preferences realistic? Did a re-ranking occur…if not – why? Was the top ranked alternative chosen? Was the outcome as desired…if not – why?
Such a decision analysis will result in a feedback loop providing the decision maker with valuable information regarding not only their decision-making style, but the specific decision problem through a process that facilitates learning and decision growth. This model is beneficial for decisions dealing with uncertainty that allows the decision maker to utilize all known useful criteria as well as account for the possibility of unknown information to be used for cross-referencing and ranking alternatives. It also allows for flexibility in the feedback loop to account for environmental uncertainties that might occur.
Have you attempted this type of model before? What other decision making challenges have you faced?
