Abstract: System, toolbox and method are disclosed for a computer-automated process/procedure mapping system that guides development and use of decision-making and knowledge-acquiring processes. The process mapping system comprises a decision-tree diagram with templated decisional logic blocks configured for dropping selected questions therein, a question bank that stores plural questions on a given topic, a process creation mechanism coupled between the question bank and the decisional logic blocks to produce a process diagram based on a series of questions selectively sequenced by and conditioned on future responses thereto produced by a user, the process diagram comprehending conditional response paths, and a process engine coupled with the process diagram that is configured to interpret the decisional logic blocks and their response paths and to guide a user through a sequence of selected questions and responses made thereto during a diagnostic and prescriptive use session.
