Jeffrey Miller is the engineering group manager for Throughput Analysis and Simulation (TAS) at General Motor’s Global Technical Center, where he leads a team of engineers dedicated to improving future programs and existing plant throughput performance. As a systems development manager, he was at the forefront of developing 3D simulation modeling capability of human movement. As a lead industrial engineer at GM’s Orion assembly plant, he led a team of IEs who helped launch the Bolt EV, the first mass produced electric vehicle to be built simultaneously on production lines with traditional gas-powered vehicles. Utilizing simulation technology and TOC training, the TAS team identified and eliminates bottlenecks in both planned and actual production processes. Utilizing simulation technology and TOC training, the TAS team identifies and eliminates bottlenecks in both planned and actual production processes. Jeff holds BS and MS degrees in industrial and operations engineering from the University of Michigan.

30 Years of Success: TOC and Throughput Improvement at General Motors. In 1987, GM’s new Detroit Hamtramck assembly plant was struggling to make its demand numbers. Working with GM Research, plant engineers developed the Throughput Improvement Process (TIP) which focused resources and improvements on the bottleneck. Throughput improved with each iteration of the TIP process and it wasn’t long before the Hamtramck plant went from the worst plant in the corporation to the best. GM has seen a torrent of changes in 30 years, but TIP continues to run. Today, every GM plant has a throughput improvement engineer, every machine collects data from the day it’s turned on, and every design change to the plant must go through the simulation process based on TOC. As GM moves toward an industry 4.0 transformation, the future includes more advanced throughput analytics that will build on and enhance the TIP track record of success.
