Zero Defects – again!
Interesting comment to this post:
We are Hyundai Translead a trailer manufacturer located in Tijuana Mexico. This year third quarter have been though for our business and that’s why our General Manager have requested QC department (I’m QC manager) to look a program to drive defects to “zero”. Reading your comments I wonder if you can give me some directions for the type of steps I should follow in order to implement such a program like “zero defects”.
My comments:
I refer you to this excellent page by John Hunter:
or this:
The latter article makes the point:
Since the slogan zero defects implies immediate compliance to a defect-free standard, it may not leave time for the continuous improvement process to occur. In fact, it may even slow down the continuous improvement process because of the massive resources that inspected-in quality entails.
Zero defects is a message that can carry with it confusion and misinterpretation, mixed with technical impracticality. It may be appropriate that the idea of zero defects be replaced with a policy of “zero escapes,” since the latter has limited interpretation. As a company is doing all it can to improve the product and business using continuous improvement techniques, it also needs to consider what it can do to prevent a random, low-level defect from reaching the final customer. In this regard, zero escapes of defects may be a complimentary activity to continuous improvement.
In other words forget zero defects, focus on improving continually!
