Gray, 1987

Paul Gray notes "In building a model for the manager that represents the elements of a business decision, you make a number of assumptions about the nature of the present and the nature of the future. You make choices as to what are the important variables, what present and past data are applicable, and how the variables are related to one another. You also make assumptions about the effects of time. More interesting, as Keen and Wagner point out, your assumptions encode your beliefs, hopes, and dreams about the future, your fears about what the future may bring, and your habits of thought from the past on how the world works. The role of a decision support system is to allow the decision maker to deal with assumptions." (p. 18)
