Doctoral Dissertations


"Through an example, led at a leading medical device company, this dissertation will demonstrate that by applying certain lean principals and tools to the development of a medical device, shortened development times can be obtained. The two papers presented in the dissertation will fill a gap in current literature. Literature presents lean techniques and applications used in many different industries. But, due to the uniqueness of the medical device industry, these general techniques are not ideal. New methods will be used and validated at a medical device company, Covidien. Instead of trying to implement many general lean principals to their projects, these new methods will give medical device companies a step-by-step way to use these principals in a valuable way.

The first paper presented in this dissertation uses value stream mapping, Kaizen events, and other lean tools to create a new artwork process for new medical devices going through the product development process. By following the process and methods presented in this paper, a company can rank and select the sub-processes in their product development process that are most important to revamp.

The second paper in the dissertation introduces a lean-based theory for setting up the flow for development of a medical device. This theory was designed to be used for either of the U.S. Food and Drug Administration's (FDA) medical device regulatory paths: a premarket approval (PMA) (Class III device) or premarket notification (510(k)) (Class II) project. The proposed development flow is designed to eliminate waste in the development system and decrease overall development time. The methodology behind the theory will be validated through trials at a leading medical device development and manufacturing corporation, Covidien"--Abstract, page iv.
