A client was interested in product inspections, and they asked: Do you also offer a post-inspection service, for cases where the results are not ideal? That got me thinking. The answer is simple, yes, we can keep following up, but managing the way rework is done and planning a re-inspection is never a pleasing experience for the buyer. It looks straightforward (see below), but in reality, it is often a tense negotiation between the buyer and the seller: How to avoid … [Read more...]
Using Data for Quality Management: Do You Have Puzzle? Or a Mystery?
As I wrote a few weeks ago, quality control analytics can save serious costs. I listed 5 examples of such cost savings in that article. Now, the question is, what can manufacturing and purchasing managers do to utilize data for quality management? How to start? Should you look at the data they have already collected, and look for hidden insights? In that case, they have a 'mystery' on hand. Or should you gather more data, and the right conclusions will become obvious once you have the … [Read more...]
How Quality Planning Drives QC and Process Improvement
What does quality management consist of? Juran wrote about this first in 1986, and he suggested 3 types of activities that make up the "Juran trilogy": Planning Quality control Improvement … [Read more...]

How Much Does a Quality Inspection in China cost?
Understanding the cost of quality inspections in China I am always surprised by the expectations of some importers regarding the cost of quality inspections in a Chinese factory. Some importers get to talk about their project for some time, see where we would help them, and finally (almost as an afterthought) ask: "How much does a quality inspection in China cost?" The 2 categories of buyers when it comes to quality inspection costs I say "299 USD per day of work", and I can nearly hear … [Read more...]
Must-know Basics of Quality Assurance in China & Vietnam for Buyers
Many new or inexperienced importers who are outsourcing their production to suppliers in China (or wider Asia such as Vietnam) for the first time go into the process almost blind. They're later hit with crippling issues that can make the process a costly nightmare. Why? Because they were not aware of how to implement strong quality assurance in China/Vietnam and fell into some fairly common traps that can catch out 'green' importers. It doesn't need to be this way though. Read on to get … [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...]
