Zhihu industry certification is true or false.
1, Zhihu industry certification is true or false: certification, Zhihu certification, right? Yes, real person authentication, and I got face recognition. Is it true that Zhihu has a personal certification degree?
2. Zhihu industry certification is true or false: What is the gold content of safety engineers?
3. Zhihu industry certification is true or false: Is the information in Zhihu reliable? I don't think so on Zhihu! Simply put, all products should be customer-oriented. For simple products, reliability is one of the quality characteristics. For complex products, reliability may be upgraded to a single customer demand, which is at the same level as quality. In other words, for simple products, customers may only explicitly put forward performance requirements, such as air conditioning filters, or slightly mention reliability, such as light bulbs; For complex products, there will be detailed reliability requirements, which will be aimed at various working environments (working profiles), such as aircraft. Reliability is a branch of quality. You can look at the quality engineer's exam book, which has a chapter on reliability, so everything except this chapter is unreliable. This answer is a bit tricky, but it can quickly explain the relationship between reliability and quality.
You can do it on the fourth floor. You said: Is Zhihu's personal certification reliable?
Definition of quality: quality is the degree to which a set of characteristics meet the requirements.
In other words, the quality of a device depends on whether it meets your requirements. For example, the photo quality of mobile phones, if you require the real imaging effect and good color reproduction, then the quality of mobile phones with beauty function may not be good for you; And if your requirement is to take a good look at yourself, then a beauty camera with skin grinding function is of high quality to you. Is it strict in Zhihu?
Definition of reliability: the ability of a product to complete a specified task within a specified time and under specified conditions.
Products accomplish different tasks (that is, different functions), and their reliability is different in different external environments. Is Zhihu's certification credible?
Take the beauty camera as an example. If you let the camera find you in a photo every time and put you on the scene, it can only recognize you five times in ten photos, and the remaining five times will reveal your true colors (probably beautiful! ), then the beauty function of this camera is not reliable.
If you send photos to a circle of friends without looking carefully before, and later find that some photos are unattractive, thus destroying the image of the goddess (or male god), then you will say: The quality of this camera is really poor! Is industrial help true or false?
So reliability should be a branch of quality. Zhihu's personal authentication failed for the second time.
Fifth floor, user 1:
Quality = quality+reliability
Quality = deviation of actual product from specification requirements
Reliability = deviation between long-term performance and initial performance of products.
Zhang Chengwen on the 6th floor said: Zhihu bought a personal certification.
Quality is a set of inherent characteristics of products, including reliability. There are two inherent characteristics. Is it true in Zhihu?
1, professional quality characteristics;
2. General quality characteristics.
Reliability is one of the general quality characteristics. General quality characteristics include safety, environmental adaptability, electromagnetic compatibility, reliability, testability, maintainability and supportability. Is it the Zhihu Certification Manual?
So quality is a big proposition, and reliability is only a small part of it.
LNBebop said, "In an enterprise, the reliability work belongs to the quality system", but in fact, it is not appropriate to put the reliability work in the quality department, but should be placed in the design department, because only when designers design with reliability in mind at the beginning of design can they design high-reliability products and put them in the quality department. As a quality manager, how do you improve the reliability of products? Can you persuade the designer to change the design? In this way, reliability can only be reduced to superficial work, and just writing reports is of no practical use. A good reliability engineer must know a lot about product design. Is Zhihu Certification Useful?
Mosch (reliability consultant) on the 7th floor said:
Personally, I suggest separating reliability from quality. How to authenticate individuals on Zhihu?
Is the information in Zhihu reliable? The difference between them in English is: Reliabilityisqualityovertime.
China people's explanation is that the quality only represents whether the current product is good or not, but the reliability can be standardized after a period of time. Quality is just a point, but reliability is.
The above is related to certification. Is Zhihu certification permanent? It's about certification, and Zhihu certification is shared forever. I read the authenticity of Zhihu industry certification, and hope it will help everyone!
