Formal and semi-formal transfer of knowledge in the conventional object-oriented software development is seriously impaired. This occurs because it is impossible to assure both completeness and consistency of the initial body of knowledge from which the knowledge transfer may commence. In this paper we propose that better utilization of the formal transfer of knowledge requires the focus on the functional aspects of the problem domain to a much higher degree than it is currently customary. We propose that the two hemisphere model based approach, where the problem domain knowledge is expressed in terms of the business process model and the conceptual model, offers effective as well as efficient knowledge transfer mechanism, if sufficiently complete and consistent, explicit and structured, problem domain knowledge is available.
