When a change in fuel emission standards reduced demand for its N-14 truck
engine, Cummins Inc. (Columbus, IN) used Witness simulation software from Lanner
Group (Houston) to improve the post-assembly of the engine, and in the process
realized $268,000 in annual savings.
As important as it was to find these savings, however, Cummins made an even
more valuable discovery through the simulation. The company learned that Witness
could play a key role in its growing Six Sigma initiative. "The N-14 project
opened the doors for using simulation in all our Six Sigma projects," explains
Maria Pasqualli, head simulation manager at Cummins. "It showed our master
black belts that Witness could help them realize significant savings in the
Design of Experiments phase of Six Sigma."
