When it comes to whether Zhihu’s certification is trustworthy, everyone knows that some people ask whether Zhihu’s information is reliable. In addition, some people want to ask whether the things on Zhihu are trustworthy. Do you know what’s going on? ? In fact, are Zhihu’s answers credible? Let’s take a look at whether Zhihu’s information is reliable. I hope it can help everyone! Is Zhihu’s certification credible?

1. Is Zhihu’s certification credible? Is Zhihu’s information reliable?

I don’t think Zhihu is good! To put it simply, all products should be based on customer needs. For simple products, reliability is one of the quality characteristics. For complex products, reliability may be upgraded to a separate customer need, on the same level as quality. That is to say, for simple products, customers may only specify performance requirements, such as air conditioning filters, or slightly mention reliability, such as light bulbs; for complex products, there will be detailed reliability requirements that will be specific to each job. environment (working profile), etc., such as aircraft. Reliability is a branch of quality. You can read the quality engineer's exam book. There is a chapter on reliability. Then all the content except this chapter is the non-reliability quality part. This answer is a bit tricky, but Can quickly illustrate the relationship between reliability and quality.

Fourth floor:

Quality definition: Quality is the degree to which a set of characteristics meets requirements.

In other words, the quality of a piece of equipment depends on how well it meets your requirements. For example, the quality of photos taken by mobile phones. If you require realistic imaging effects and good color reproduction, then a mobile phone with a beauty function may not be of good quality for you; and if your requirement is to take a good-looking picture of yourself, then a mobile phone with a beauty function may not be of good quality for you. The skin-smoothing and functional beauty camera is of high quality to you.

Reliability definition: The ability of a product to complete specified tasks within a specified time and under specified conditions. Are Zhihu’s answers credible?

Products complete different tasks (that is, different functions), operate in different external environments, and have different reliability.

Take the beauty camera as an example. If you ask the camera to find you every time in a group photo and take a photo of you, but it can only recognize you five times out of ten times, the remaining If your true face (which may also be beautiful!) appears five times, then the beauty function of this camera is not very reliable. Is Zhihu personal certification reliable?

If you posted the photos on WeChat Moments without looking carefully, and later found out that some of them were not beautiful, thus destroying the image of the goddess (or male god), then you would say: This camera The quality is really bad!

So reliability should be a branch of quality.

5th floor user 1:

Quality = quality + reliability. Is Zhihu’s personal certification of academic qualifications true?

Quality = the deviation between the actual product and the specification requirements

Reliability = the deviation between the long-term performance of the product and the initial performance

Zhang Chengwen on the 6th floor said:

Quality is a set of inherent characteristics of a product, including reliability. There are two types of inherent characteristics. Is Zhihu strict?

1. Professional quality characteristics; can you trust what you see on Zhihu?

2. General quality characteristics.

Reliability is one of the general quality characteristics. The general quality characteristics include seven categories: safety, environmental adaptability, electromagnetic compatibility, reliability, testability, maintainability, and supportability.

So quality is a big proposition, reliability is only a small part of it. Can Zhihu personal authentication be seen by others?

LNBebop said above, "In enterprises, reliability work belongs to the quality system." But in fact, it is not appropriate to place reliability work in the quality department. It should be placed in the design department, because only in the design department In the beginning, designers take reliability issues into consideration when designing, so that they can design high-reliability products. If they are placed in the quality department, how can you, a quality management person, improve product reliability? Can you persuade designers to change the design? In that case, reliability can only be reduced to superficial work, and just writing reports is of no practical use. A good reliability engineer must have a good understanding of product design.

Mosch (reliability consultant) on the 7th floor said: Are the revelations on Zhihu credible?

I personally recommend keeping reliability and quality separate.

The difference between the two in English is: Reliabilityisqualityovertime

The Chinese explanation is that quality only indicates whether the current product is good or not, but reliability can standardize whether the product will be good after a period of time. Quality is just one point, but reliability is whether the things on Zhihu can be trusted.

The above is related to whether Zhihu information is reliable, and it is about the reliable sharing of Zhihu information.

After reading whether Zhihu’s certification is trustworthy, I hope this will be helpful to everyone!
