Requisite decision models

'[A decision] model is requisite when the decision makers's thoughts about the problem, beliefs regarding uncertainty, and preferences are fully developed'
Clemens, R.T. 1997. Making hard decisions, 8

'The only way to get to a requisite model is to continue working on the decision until all of the important concerns are fully incorporated. Sensitivity analysis (...) will be a great help in determining which elements are important'
Ibid., 67
