Why A QC Inspector Man-Day In A Factory ISN'T 8-10 HoursSome buyers who haven’t spent much time in Chinese factories have some common misconceptions, including innacuracies about a QC inspector’s man day, or stories like: “Chinese production operators are forced to work 12 hours a day, in a case of modern slavery.

The misconception about man-days is that a good inspector will spend 8-10 hours working at the factory during their work day. This article debunks this.

In fact, the man day that you’re charged for has to account for more than just direct ‘work’ at your supplier’s (or your own) factory.

Here are a series of ‘realities,’ that help to explain why this is the case and give you a broader understanding of what a man-day includes.


Reality 1: The QC inspector doesn’t live next to the factory

No company in China has a network of inspectors within 30 min of every manufacturing facility. There are times when the factory closest to an inspector is still 2 hours away. A round trip takes 4 hours.

The high-speed rail (gaotie) network has made many trips shorter, but it doesn’t connect all cities. Taking inter-city buses is still common. And the mass of people there often causes congestion. Just getting to the high-speed rail station, dealing with traffic and crowds, sometimes takes longer than the actual trip. We can’t avoid this by parachuting onto the factory grounds.

And, if your factory is a bit inland and 3 hours away from the closest major city, the round-trip alone might take an entire day. Factory areas can have an even worse infrastructure (more people still on motorbikes, bike roads, and entrances not marked).

We invoice only 50% of a day spent only on travelling, but it ends up in the cost nonetheless. It is not a rare occurrence.


Reality 2: The inspector doesn’t just show up and inspect — there are other tasks in his/her man day

Before going to perform a product inspection, the inspector needs to study the client’s documents, in case it is a one-shot job. It is unnecessary for regular, high-volume clients because the staff gets specific training, but that’s not feasible for all clients.

When they show up, they don’t walk into the factory and directly opens cartons. After that, they don’t start rapidly checking in a whirl of professional silence. Like any professional in any country, there are necessary introduction steps.

People don’t think about the counting & sampling process, for example. Doing it right takes time. And doing it wrong means the report can’t be trusted…

And what consumes a lot of time is putting the findings together in a way that is easy to understand. It usually can’t be done at the factory, where sales reps of quality technicians might not let the inspector work in good conditions. In some cases, the tone of discussions is downright aggressive, and there is no way to collect one’s thoughts. So, that’s about 1 hour of focused work to do outside the factory that’s built into the QC inspector’s man day.


Reality 3: There is no way to keep working straight through lunch

Foreign buyers think, ‘what is the problem? When I am at the factory, we can order food in and plough through in the conference room.’

This might be possible sometimes, but usually, the factory reps want to have a break and they take their ‘guest’ outside for food.

If the factory personnel has a 90 min break (which is pretty much a minimum in China), they don’t want to be forced to ‘monitor’ a QC guy. They want their rest too! They aren’t going to allow the inspector to operate solo while the facility is officially closed.


Reality 4: Spending more 6 hours in a day, more than 4 days in a row, on visual inspection is quite tiring

After a few days of continuous work, around 4 pm, the eyes simply shut down. Defects are no longer obvious. That’s a very dangerous zone to be in. It is simply not possible to keep going and do a good job.

Overall, it means a good target for an inspector’s man-day is 5 productive hours in a day spent in a given factory. And, if the factory is hard to reach, that sometimes dwindles to 3-4 hours. The key is to take this into account at the time of quotation (and decision of the sampling), otherwise, the job has to be rushed (and that might lead to non-detection of serious issues, which is much, much more expensive than paying for a 2nd man-day of QC work).

A good quality control partner knows what to look for. It’s not the “more hours spent, the merrier”. It’s all about using time effectively and knowing the key points to look for.

Note: If an inspector is stationed there for days at a time, it is different for several reasons. He might stay in a hotel just next to the factory. He might spend some of his day patrolling the fabrication/assembly stations (less tiring on the eyes). He is already trained and knows what to focus on. That’s a different story.
