How to reduce the frequency of quality inspections

by Renaud Anjoran on 23 January 2012

Over the last month, I received several messages from readers on this topic. So I tried to think of a few ways to reduce the frequency of QC inspections without taking high risks.

1. Two methods I approve of

The two most common solutions are:

  • Reducing the inspection severity (i.e. checking a smaller number of samples by choosing the “reduced” severity);
  • Skipping some lots randomly.

But then, how to select which orders can receive a “lighter dose” of quality control? In the words of one of the importers who wrote to me:

We write PO’s to many factories and my gut tells me which factories are good factories with regard to quality but it is difficult to quantify. What would be your suggestion to quantify this?

The ISO 2859-1 standard actually gives a method to switching from normal severity to reduced severity, when a factory get to a certain score. I reproduced a summary of the switching rules below.

If you want to follow this rigorous process, you should work hand in hand with a quality control firm — unless you are already familiar with this standard.

Inspection Switching Rules

I don’t know of any rigorous method for determining which manufacturers deserve a “skip lot” procedure, though.

As a rule of thumb, if two inspections in a row on reorders of the same product are fine and you trust the factory owner, you can switch to controlling only 50% of their shipments. Make sure the skipped lots are announced at the last moment, and in a randomized manner.

[UPDATE: please don't miss the first comment below this article, which offers some great ideas on this topic.]

2. Some other methods you should avoid

As I wrote in How to reduce your QC inspections budget?, I have seen buyers take decisions without much thought, with disastrous results:

Bad ideas to reduce your quality control expenses:

  • Skip inspections on all orders below 20,000 USD (for example)
  • Pay only for 1 day of inspection, even when the professionals advise to spend several man-days
  • Look for a cheaper provider of QC inspections (in China there is always a lower price, but the service is usually quite different)

Do you agree?

Training for QC inspectors: Q&A with an expert

by Renaud Anjoran on 17 January 2012

HubertI recently had the opportunity to work with Hubert Delelis Fanien, founder of Aka Outspring. He has set up a training center for QC inspectors in Shenzhen, China. He also helps local companies hire and evaluate their inspectors.

I was impressed by his unique teaching approach and by his experience in managing Chinese staff. He was kind enough to respond to my questions.

Q: Can you tell us a little about your background and how you developed the methods you use to teach QC inspectors?

In my 16 years working for a major French multinational — including 12 years as a Business Unit Manager in China – I have recruited and trained hundreds of Chinese team members.

My mission was to ensure customer satisfaction through Quality. I had to adjust my training and coaching method in order to become more effective. I had to adjust the way of delivering the competency, rather than the content itself (which is exclusively concrete, with a strong focus on the “sense”). My teaching method has been validated in the field, through trial and error (doing and then measuring results).

I used this experience to set up an exclusive and unique Operational Training Center [see below photo].

Training center for inspectors in China

Q: What service would you offer to a sourcing office with, say, 5 inspectors on the ground and no in-house training/auditing system?

The aim of my company is to transmit competency: to make people and their organization autonomous. So my offer would be :

  1. Train the team and provide the coaching tools,
  2. Identify the person capable of being an instructor,
  3. Coach the future instructor to create and implement the training on his team.

Our objective is autonomy by creating a learning cycle.

Q: What are the most widespread mistakes committed by inspectors in their job?

I have observed 3 major mistakes and/or difficulties that impact systematically reliability and efficiency of the inspection:

  1. The way to pick cartons for inspection (randomness does not mean there is no procedure to follow),
  2. The variance between 2 inspectors in judging the same non conformity,
  3. Missing or forgetting control points (non-respect or non-existence of the sequence in the inspection process).

Q: I noticed that you spend some time explaining to the trainees what a foreign buyer expects. What are the most frequent causes of misunderstanding?

Probably the most frequent cause of misunderstanding is the difference of value of a “YES” for a Westerner and for a Chinese.

As a Westerner, there is only one value, only one level. From a Chinese perspective, I used to say there are 3 levels: “yes, I hear you”, “yes, I understand you” and “yes, I will do”. You’d better know which one you are getting when your Chinese supplier replies “yes” to you!

Q: You also search and evaluate candidates for the position of quality manager. What traits and skills do you look for?

I always focus on personalities, because competency can be learned while personalities don’t change.

Each position and company will require specific traits. It is important to know and observe how the company and its employees work, in order to identify which traits will increase the chances of integration and future success inside this company.

For the position of Quality Manager, the candidates with the most suitable personalities will demonstrate :

  1. An active attitude (a passion in acting, doing, using his hands),
  2. A masculin dominant character (a desire to do well, strong convictions, and a willingness to go ahead),
  3. A rational intelligence (capacity to extract patterns and to identify links between situations).

All those attitudes will make it easier for the candidate to identify non conformities and variances, to convince their co-workers, to obtain concrete action plans, and to lead permanent progress.

Understand the Chinese side in your negotiations

16 January 2012

There are frequent misunderstandings between importers and their Chinese suppliers, and they could be avoided if the purchaser placed himself in his supplier’s shoes from time to time. Andrew Hupert came up with an excellent reminded in American Negotiating Culture – Through the Eyes of the Chinese Counterparty. He describes the American style, but most of [...]

The 2 types of inspection companies

7 January 2012

Let’s say you are an importer, looking for a provider of QC inspection services in China. You will evaluate candidates on how serious they look, on their size, and maybe on their knowledge of your product line, right? Well, you’ll be missing one important question: are they focused on flexibility or on reliability? Inspection firms [...]

Managing independent quality control: what it takes

5 January 2012

Some importers often over-estimate the amount of time it will take them to manage a third-party quality control (QC) firm. So I made a list of the main “touch points” and of the required steps. Writing clear specifications and/or sending a reference sample If you appoint an independent quality inspector and you want to make [...]

Timing for a final random inspection

28 December 2011

As part of their quality control plan, importers should decide when final random inspections should take place. As I wrote a while back (see here), each option has drawbacks. An earlier inspection is easier on the factory, and it allows for a faster shipment. BUT the inspector’s conclusions are less reliable and less comprehensive. My friends at [...]

Social compliance audits don’t work!

Scams by Chinese suppliers: what to do?

19 December 2011

At least once every 6 weeks, I get an email from the victim of a scam performed by a Chinese supplier. They ask me whether someone can help them recover the money. Sometimes it is a scam (seller asks for a deposit before shipment, then ships nothing and stops responding to emails), and sometimes it [...]

How a letter of credit protects importers

16 December 2011

As I explained before in Confirming quality when paying by irrevocable letter of credit, an importer can pay his suppliers through letters of credit (L/C). An L/C triggers the payment once the bank receives a pre-determined list of documents from the supplier. It protects buyers much more than a regular bank wire, since there is no [...]

Troubleshooting process in a Chinese factory

13 December 2011

I have been to Chinese factories a few times for solving problems. In one case, the factory pretended the goods really couldn’t be made as intended by the importer (that was true). In another case, the QC inspector found many defective goods that seemed to come from the same issue, production was still running, and [...]

Piece by piece inspection: pros and cons

9 December 2011

Some buyers don’t want random inspections. They don’t trust the manufacturer to produce consistently at the right quality level. So they need to check 100% of the goods. A few months ago, I described inspections on a platform, where the shipment is inspected outside of the factory before being shipped out (if it is accepted for [...]
