| * **Knowledge Sharing** - Models and their results present an explicit and communicable understanding around which consensus may be built. They also provide a platfrom through which corporate memory may be transferred or preserved. | * **Knowledge Sharing** - Models and their results present an explicit and communicable understanding around which consensus may be built.

| * **Coherency** - Scenarios must assure consistency among the input variables both over time and within time periods. For example, in an energy model, population and the services required by the population determine the level of economic activity. The level of economic activity in turn creates demands on the energy system. The way in which the energy system meets energy demands controls the emission of greenhouse gases and criteria air contaminants. The model assures coherency through the use of stock-flow accounting rules, base stocks and life tables, supply/disposition balances for fuels and feedstocks, and the explicit representation of energy transformations. | * **Coherency** - Scenarios must assure consistency among the input variables both over time and within time periods.
