Development of a Design Method to Reduce Change Propagation Effects - October 24

The public who is interested in containing engineering changes during production, are invited to a dissertation defense in the Department of Mechanical Engineering at Clemson University.

Mr. Prabhu Shankar will defend his research that has been developed and validated with industry partners at International Truck, Reliable Sprinkler, Chrysler, and Robust Systems and Strategy, LLC.

Date: Monday, October 24, 2011
Time: 8:30 - 9:45 am
Location: EIB (Fluor Daniel Engineering Innovation Building, Department of Mechanical Engineering) on Clemson University Campus

Interested parties should contact Dr. Joshua D. Summers ([email protected]) to secure parking passes by Thursday, October 20, 2011.


Design changes during the production phase are necessary yet expensive. These changes may result in a cascading effect, thereby significantly affecting the product lead-time and the profit to the organization. Therefore, in order to maintain the product integrity while conducting the design changes, a systematic seven-step method has been developed and tested in industry, such as commercial vehicle manufacturer, rolling mill industry, passenger car manufacturer, and an automatic fire sprinkler manufacturer. This method helps line sustaining engineers/product support engineers to systematically develop the verification, validation, and test (VV&T) plan for a product family with different variants in a collaborative environment. The documents these engineers generate by using this method will enable them towards a better understanding of the system, necessitate the need to communicate between the design and other departments, assists in prioritizing the tests, and managing the test schedule; when necessary, it can also be used as an evidence to present to the legal authorities. An automatic fire sprinkler manufacturer applied this method in a live design change project. As a result, they saved $4000 and 1-3 months of project lead-time.
