Dealing with complex systems often involves a layering (e.g.: hierarchical) representation that is
prevalent throughout engineering. This layering appears in various disciplines in a variety of forms. Concurrent
design refers to a generalized methodology for mapping from the functional requirements and conceptual model
to blueprints in various domains. Cyber-Physical, hence complex, system include mechanical, electrical,
sensors, computer, data, user interface, and external factors. The system is capable of acquiring historical data,
receiving real-time sensory status, adapt accordingly while interacting with the environment. The purpose of this
paper is to introduce a novel design methodology approach for smart complex systems such as cyber-physical
products and machines. The potential impact of this methodology is to provide a common design approach for
any smart system. It can also be used to calculate system complexity in the context of the coupling index.
Additionally, it can reduce the compatibility issues at the early system design level.
