In health care, the design, development and commercialization of innovative products is often found frustrating due to the slow inefficient and difficult nature of its systems. One part of this problem is the fact that health systems are highly regulated complex systems that include various stakeholders and unique challenges. Nevertheless, designers and other innovators are
often unaware of these unique features of health systems. It is important that designers and managers are able to understand the system, anticipate challenges and account for them in their work.

We therefore aim to establish and evaluate an overarching conceptual model, which can delineate both the systems of health care innovation process and the relevant stakeholders in these systems. This paper reviews the application and potential benefits of one of the promising models called Multilevel Design Model (MDM) by employing an expert-participatory testing on multiple cases in documented clinical reports (n=8). The evaluation of the MDM model followed by further adaptations and changes to the model itself, as well as to the accompanying user guidelines. With some adjustments, the MDM was able to visualize and explain the systems of the health care innovation process in a systematic and shared manner usable for health product designers, innovators and health organizations. We propose the adjusted MDM model for further use in the design and development of health care innovations in order to avoid the typical stagnation of product dissemination after implementation.
