“We can track every packaged container in each lot, and that’s greatly improved the accuracy of our inventory tracking,” explained Swanson. “Before Plex, we usually needed to adjust our annual inventory by about $70,000. Now our adjustments are negligible – around $15,000 or less.
Cost of Quality Cut Nearly in Half
Today on the E&E plant floor, Plex-generated quality checksheets must be completed before any job is run. The system randomizes the details on the checksheets, ensuring they are carefully reviewed for each job.
For each operation, if the associated checksheet isn’t completed, the machine stops production. The checksheets require supervisor sign-offs. If something is out of spec, the supervisor won’t sign off on the part, and this prevents any quality issues or production delays.
Before, with manual operator checksheets and a manual process, it was hard to catch quality issues until the problems had grown.
Plex’s checksheets and other controls on the plant floor have enabled E&E to reduce its scrap, rework, delays and other factors that contribute to the cost of quality. The measurable results are impressive.
Within just the first year of launching Plex, the company reduced its Cost of Quality (CoQ) by 42 percent.
