The question-answer approach for the development and usage of the expert system (ES) is suggested. It corresponds with the dialog nature of the expert knowledge extracting and the real time extraction of precedents from the knowledge base by the user. All functions of the ES are presented as corresponding tasks for each of which the specialized question-answer program (QA-program) is created. The execution of QA programs is organized in the form of modeling. QA programming and QA-modeling are being implemented in the environment of the specialized QA-processor which was developed originally for the conceptual design of software intensive systems. Processor is implemented in several versions the last of which is fulfilled as the instrumental environment for programming.
