Is Zhihu's professional experience true?
1. Is Zhihu's professional experience true? Is Zhihu's information reliable? Zhihu, I don't think so! 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 authentication true?
Definition of quality: quality is the degree to which a set of characteristics meet the requirements. What's the experience of working in Zhihu?
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. Zhihu certified professional information is true.
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.
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! Are all the educational experiences in Zhihu true?
So reliability should be a branch of quality.
5th floor user 1: How's the work with fish, Zhihu?
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 sixth floor said:
Quality is a set of inherent characteristics of products, including reliability. There are two inherent characteristics.
1, professional quality characteristics; Are the people above Zhihu really that good?
2. General quality characteristics. Is it reliable to go to work in Zhihu?
Reliability is one of the general quality characteristics. General quality characteristics include safety, environmental adaptability, electromagnetic compatibility, reliability, testability, maintainability and supportability.
Are many stories in Zhihu made up? So quality is a big proposition, and reliability is only a small part of it. Have you ever lied about your work experience?
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.
Mosch (reliability consultant) on the 7th floor said: Is it true to go to Zhihu?
Personally, I suggest separating reliability from quality.
Their difference 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 about the reliability of information in Zhihu and the reliable sharing of information in Zhihu. After reading Zhihu's professional experience, is it true? I hope it will help everyone!
