On August 12 at 12:00 EST, Albert Eisele will be presenting a webinar regarding strategic plannning for designed experiments.
Testing one factor at the time (OFAT) will always fail when interactions are present. That’s why we use Six Sigma and DoE to find the root cause.
This presentation is based on a project conducted at Ford Motor Company Vehicle Operations Saarlouis and supplies the needs of a data driven problem solving approach using the six-sigma methodology. This was a real problem in a complex production process using a completely new technology, and therefore DMAIC was chosen as the appropriate discipline.
Unfortunately, the first DoE was not set up properly, according to Six Sigma guidelines and the team found little significance with the variables. They were ready to give up! The second DoE, set up properly to study interactions and create contrast, resulted in resounding success.
At the end, the project team achieved a savings of USD $700,000 per year by eliminating all defects, coming down from a 15% defect rate to zero defects.
