Shared Vision Planning

Reasons for Less Than Successful Use of Computer Models

(Excerpt)

Reasons why the use of computer models, in general (including shared vision models), has been less than totally successful (Loucks et al. 1985).

  1. Unless model builders are familiar with both the problem and institutional setting in which the problem is to be addressed, it is unlikely that any model will be effective in obtaining a solution.
  2. The model is not complete and able to examine all issues deemed important by the user.
  3. The model is not compatible with the conceptualization model users have of the problem
  4. The model is not capable of including subjective information in the modeling and decision process.
  5. The model is not capable of developing and encouraging trade-offs between alternatives.

And, “Perhaps one of the biggest reasons for model solution rejection, even as a basis for discussion in the managing, planning, or policy-making process, has been the lack of adequate communication between the analysts and their clients.”
