Smart industrial and consumer products are developed towards autonomous operation. These products have capabilities which require operation by cooperating systems. Engineering of these products must be elevated to system level for innovation and life cycles. This demands system level model which has the capability to provide integrated support for lifecycle engineering. Serving connected systems, the system of systems engineering (SoSE) theory, methodology and practice gained leading role in industrial practice. This paper introduces system of systems (SoS) based integrated engineering scenario which includes organized intellectual property (OIP) model system, systems engineering (SE) based model system which represents smart cyber physical system (CPS), and cyber units of systems operated CPS. Following this, situation awareness (SA) in SoSE based communication amongst systems in the above scenario is discussed considering SA as main goal. Next, novel OIP model system is proposed as a possible contribution to the above scenario. Finally, system level experimental model is introduced which will be applied as main method in the virtual research laboratory (VRL) at the Laboratory of Intelligent Engineering System (IESL) among others to accommodate system level engineering in research for OIP and PhD research at the Doctoral School of Applied Informatics and Applied Mathematics, Óbuda University.
