Conceptual solution of the tasks in designing the software intensive systems

The key problem of successful developing the software intensive system (SIS) is adequate conceptual interactions of stakeholders at the early stages of designing. Success of the development can be increased with using of Artificial Intelligence means including models of reasoning. In this paper a number of question-answer means (QA-means) for modeling reasoning is suggested. The base of such means is a QA-method for the conceptual solution of the design tasks. Conceptual solution of any design task is aimed at building a normative set of conceptual models and documents. The QA-method organizes and integrates in real time all conceptual solutions which are building collaboratively in all workplaces of the corporate network.
