Many sensitivity analyses based on scenarios, including procedures to randomise across model uncertainty, relate to descriptive dynamic mathematical models with the user of the models characterised as an objective observer . Bayesian approaches enable these descriptive analyses to take account of the subjective choices in model construction and implementation . Organising descriptive analyses and deciding on a suitable option across a diversity of opinions among stakeholders use prescriptive processes, which can be supported with prescriptive modelling tools . These approaches are subjective, in that they are constrained or directed by the particular views and emphases of the decision-making group . Not all tools are appropriate for all these activities.
