There are rules that are used to provide statistical outcomes such as a percentage, number or cost. These can be categorized as complex rules and are normally based on legislation. Not all rules used in the human services domain deal with such complex calculations. Often, the decision could be arrived at by answering a number of yes/no questions, and the outcome could not be a statement of financial entitlement, but rather a statement of a client's situation, such as eligible or not eligible, safe, unsafe or conditionally safe. The determination of these decisions are done by comparing the evidence collected against what is configured to arrive at an outcome, there are no calculations required. Decision Assist supports the configuration and execution of such simple rules.
