Scientifically experimental way-of-working in conceptual designing of software intensive systems

Inclusion of experimenting into way-of-working used by a team of designers facilitates increasing a degree of successfulness in designing of Software Intensive Systems (SIS). This paper presents a scientific approach to experiments the objects of which are units of designers´ behavior aimed at solving the project tasks in conceptual designing. The offered approach is based on specifying the behavior units as precedents and pseudo-code programming the plans of experiments. Reasoning used by designers in experiments is registered in question-answer forms. Experimenting is being supported by a specialized toolkit.
