Abstract: A system is provided for managing a data structure based variable rules engine. The system includes a processor, a set of questions, a variables data structure comprising values and a set of variables, a results data structure comprising a set of requirements, a user interface, and a rules engine. The user interface outputs the set of questions and receives responses to the set of questions. The rules engine, when executed by the processor, assigns results to the set of variables by combining the responses with the values in the variables data structure, and determines whether the results meet the set of requirements in a results data structure. The set of questions, values, responses, and results are associated with a plurality of time frames. The user interface also outputs the results for the plurality of time frames in response to a determination that the results meet the set of requirements.
