Sharp tools can do a good job.

No matter which industry we are determined to do or what kind of work we do, the preparation before work is very important to our success or failure. Therefore, before we plan to inspect the goods, the inspection preparation is very important to us, even enough to determine the success or failure of our inspection work that day.

My suggestion is: on the day before departure, make a draft of your next day's work flow in your notebook and preview your next day's work in advance, which will help you clear your mind, predict some unexpected situations, think of countermeasures and prevent omissions.

In my previous job, I once met a QC, and I asked him to help me go to a factory in Shantou for product inspection. The day before departure, I called him and asked him to contact the factory to confirm the date of inspection, the address of the factory and the completion of the goods, so as not to make the trip empty.

After listening to my words, he said, "Do you mean to let me contact the factory now to see if the goods are ready?

Don't you have to go if you can't do it well? "

I said, "Yes."

Then he said to me, "I'm QC, and I'm going to inspect the goods." Do I still have to take care of the factory? " I will go to the factory. Look when you have it, and come back when you don't have it. If you want me to confirm in advance, you'd better find someone else. I'm not going. "

It seems to be right. As QC, we will inspect the goods when we have them, and we will come back when we don't have them. But he forgot that what the company asked you to do, whether as QC or other positions, was to hope that everyone could look at the problem from the company's point of view. If after arriving at the factory, the factory says that the inspection date has been changed, or the inspection is carried out in their branch factory, can these unnecessary troubles be avoided? Think about it. Finally, you went to the factory without inspection, and then went back the same way. Do I have to pay you? If I pay you, will the company ask you for cooperation in the future? Do you want to cooperate with this company in the future without paying you? We have been in this situation before.

No matter where you stand, if you can put your position higher and see farther. Treating work with the attitude of the host will make you go further.

Anyway, let's look at a table first:

3.4 Inspection Operation Guide

The following is the general process of inspection. Of course, it is not static. Many processes can follow each other. If you find it convenient and suitable for you, then boldly make corresponding changes according to your own preferences.

The basic process of inspection is as follows:

Arrive at the factory-> meet the factory representative-> briefly introduce the inspection arrangement-> warehouse number-> warehouse box extraction-> sample box delivery to the inspection room-> unpacking sampling-> product inspection-> defective product labeling-> defective product record-> defective product/packaging photos-> inspection results and

Below I post a general inspection process in practice (English). You can feel it and check your English. If you don't understand, you can try it according to the method we said above.

How about it? Do you have a general understanding of the inspection process?

Next, we will introduce the key control points and operation suggestions of each step in detail from the step of warehouse inventory, so as to ensure that our inspection results can represent the real quality level of the inspection lot to the greatest extent.

3.4. 1) Warehouse points

The inventory work is mainly to check the number of boxes and the total number of boxes on site to confirm the finished state and the authenticity of the finished state of the products, so as to ensure that:

The completed production quantity can meet the large enough sample number, so as to restore the real quality level of the inspection lot to the maximum extent.

The authenticity of the finished product, to ensure timely delivery after the factory inspection.

Minimize the hidden danger that the factory relaxes the quality control of mantissa products after receiving the conformity inspection report, resulting in high unqualified rate of products.

The main cases I have seen:

The factory didn't complete the required order quantity, but in order to meet the inspection arrangement of the guests, empty boxes were placed in the middle of the cargo pile to fill in the quantity.

The factory did not complete the specified order quantity, and the unit asked the inspector to write more product quantity in order to meet the inspection arrangement of the guests. Finally, when the guests arranged for shipment, the factory said that 50% of the goods could not be shipped before they were completed, which was an economic loss.

The inspector only counted the total number, not the number of each model and color. Finally, some models or some colors are shipped more, while other colors are shipped less.

The quality of the products inspected is very good, but the quality of the big goods exported to the guests is very poor.

Suggestion:

Count and pay attention to whether there are empty boxes when sampling.

As inspectors, we should always remind ourselves of the duties and professional ethics of inspectors. We can't lose more because of less. As the inspector's manager, we can ask the inspector to take pictures of the whole cargo pile when taking pictures, and we can see how many boxes there are from the pictures. This is done to avoid overstating the quantity.

As inspectors, we should try our best to confirm the quantity according to the product type/color. We should make sure that our work is orderly, especially for orders with large amount and many colors. We won't confuse ourselves.

Example: I once asked an inspector to help me go to Cixi to inspect the goods and supervise the loading of containers. After checking and packing, he didn't even know how many items had been packed and how many were not finished. Is it frustrating to have to call the factory at last? His main problem is that he only calculated the total, but not the number of each item. Finally, some models have more colors, while others have less colors. The box is still in the factory, and finally we have to arrange express delivery abroad.

The quality of products is good at inspection, but the quality of export commodities is poor. The possible reason is that a small part of the product is made and then inspected. After passing the inspection, the factory relaxed the quality control, so the quality of the goods finally exported was relatively poor. Of course, there are other reasons, which you will see in the subsequent chapters of this book.

3.4.2) Warehouse Box Diagram

In the process of drawing boxes in the warehouse, it is mainly to ensure that the sampled samples are random, which can restore the real quality level of the inspection lot to the greatest extent.

Past cases:

I don't know how many boxes to draw, resulting in a small proportion of boxes to be drawn.

Boxplot is too concentrated in a certain area, a certain batch number and a certain production date, which leads to the unrepresentative samples.

There is no aisle left in the factory's cargo pile, and the boxes nearby can't be drawn out, which leads to the unrepresentative samples.

After leaving the box, the factory did not draw the box drawn by QC.

Suggestion:

The number of boxes to be drawn is based on the root number of the total number of boxes. For example, 100 cases, open the root sign, and then draw 10 cases.

I used to do quality system inspection in a large home textile group in Beilun, Ningbo, so I won't mention the name of the factory. Because the sampling method of the factory was not seen in the product inspection report of the factory, I asked the quality manager of the factory how they determined the sampling number of boxes.

She replied: "We sampled according to the inspection quantity on the AQL sampling table. If the total number of products is 65,438+00,000, we will take 200 samples. "

I asked her again, "How many cartons did you take for 200 samples?"

She was a little angry and said, "We smoked 200 cigarettes according to AQL. Why do you always ask me to smoke by the box? " . The implication is that you understand sampling.

In this example, she ignored the size of the sample box and only grasped the number of samples. Let's give a more detailed example: suppose there are 10000 sample batches, and each batch contains 100 products, with a total of * * * 100 boxes. According to the general two-level sampling scheme of ISO2859, the number of samples is 200, and each sample contains 65,438+000 products. If we only suppress the sample,

Then someone asked, what if the total number of cases is less than 10? For example, 9 cases, or the root number? In this case, my personal suggestion is to smoke it all. All under 10 cases.

When drawing frames, we can allocate frames reasonably according to the number of frames. For example: ** 100 cases, then 1 case in 1 case, 1 case in/kloc-0-20 cases, and so on. If there is mantissa, it is recommended to draw mantissa.

Similarly, we can reasonably allocate (if applicable) our sampling plan according to date code, batch number and production workshop.

In practice, we have encountered some factories deliberately stacking goods in places that don't leave the aisle, so that you can't extract the innermost products. Then what should I do? There is no shortcut, so we can only try to move the cargo pile to extract the goods inside. This is done because: first, we have the responsibility to ensure the randomness and representativeness of sampling; Secondly, there are always very few factories that use this low-level means to pile up defective products at the bottom to avoid inspection. Some factories even put some empty boxes in the innermost part of the cargo pile to achieve the purpose of filling in the numbers.

When picking up boxes, we'd better write down the box number of the picked-up boxes in our notebooks, sign or mark the picked-up boxes, and then ask the factory to help us pick up boxes from the cargo pile. The purpose of this is: first, it is convenient for you to know whether the factory has pulled the goods out of the pile according to the box you drew; Second, a guest asked to write down the number of boxes drawn in the report. If they are slightly experienced employees, they will write down the box number they have drawn to examine the rationality of their sampling. Another advantage of writing the box number on the report is that when customers complain about products, you can easily trace back whether the products in question are the boxes you sampled.

When drawing a box, it is best for the quality inspector to draw a box, and the factory takes a box from the cargo pile and puts it on the other side. Some factories will deliberately slow down and take you back to the inspection room after you have drawn all the boxes. When you leave the warehouse, let the factory workers smoke slowly, or even directly replace the goods in your box with A-quality goods that have been fully inspected by the factory QC. I did this kind of thing in the first factory where I worked.

When the inspection batches of the same model are packaged in different colors, samples should be taken according to the proportion of each color to the total. That is to say, different colors and models should be sampled in the same proportion according to the proportion of their quantity. It's a bit like an American seat. Each state always has the same proportion of members in Congress as the state's population in the United States.

3.4.3 Send the sample box to the inspection room.

Purpose:

Make sure that the sample box sent to the inspection room is the sample box you selected, and the sample box has not been changed and replaced halfway.

Past cases:

The box was replaced in transit.

Suggestion:

After unpacking, accompany the factory to transport the sample box to the inspection room.

Sign the tape on the surface and bottom of the sample box to prevent it from being opened by the factory.
