The paper presents a precedent-oriented approach to experimenting with programmable units of developer’s
activity in conceptual designing of Software Intensive Systems (SIS). The reuse of any such a unit is being implemented as a
typical work of a designer in accordance with the definite technique which is previously programmed. The offered approach
is coordinated with simplifying the complexity on the base of interactions of designers with the accessible experience the
kernel of which consists of models of assets included into Experience Base. The simplifying is being achieved by the use of
the specialized pseudo-code language in programming of assets for their reuse by designers.
Keywords/Index Terms— conceptual designing, pseudo-code language, programming, precedent-oriented approach,
