I just read the book Measures of Success by Mark Graban, and I found it does a great job of covering the basics of how managers should work with data. His whole approach is largely based on concepts from Don Wheeler's books. If you are not familiar with Don Wheeler, he is the most respected manufacturing-focused statistician of the past 30 years. Graban covers what to do in two cases managers don't like to see. Case 1: an unstable process leading to a widely fluctuating … [Read more...]
Does ISO 9001 Actually Prevent Process Improvements?
As I wrote before, I believe that a good implementation of ISO 9001 does help a manufacturer quite a bit, while a bad one will only create issues. And the reason is simple. ISO 9001 allows an organization to set any system it wants, as long as they make sense and they respect a set of minimum requirements.

How To Keep A Clean Factory And Stop Dust On A Budget

A Key China Sourcing Criterion: Can Your Factory Improve?
If you are only going to place 2 or 3 orders with a supplier, the key sourcing criteria will probably be quality, price, past production of similar products, and understanding of compliance requirements. However, if you are looking for a manufacturer you'll work with for 5+ years, you need to look at how they can ensure that the operations in their factory improve. If they are stuck in old ways, they might not be able to support your evolving needs... and, more worrisome, they will probably … [Read more...]
How a Chinese factory can REALLY improve its quality
Auditing a factory's quality system, and helping them patch the main holes found by the auditor, is helpful. But is it enough? I used to think so. A good quality management system is supposed to stop defects before it is too late. However, I have seen too many Chinese manufacturers get very high scores on a quality audit, and then try to ship batches containing 5-20% of defective goods. Setting up control points relevant to each production step does help, but improving quality takes much … [Read more...]
