Why is 100 minus 1 equal to 0?

The law of "100- 1=0" originally comes from a prison duty discipline: no matter how well you have done before, if you escape from one of many prisoners, it will be forever dereliction of duty.

In our opinion, this discipline is too strict. However, it is extremely necessary to prevent criminals from endangering society again. Later, this regulation was introduced into enterprise management and commodity marketing (including service industry) by management scientists, and soon it was widely used and circulated.

It tells us that for customers, the quality of service is only good or bad, and there is no comparison level between good and bad.

The good is all, and the bad is zero.

This is a famous theory with far-reaching influence, called Murphy's Law. The law points out that if everything has the objective possibility of an accident, no matter how small it is, if it happens repeatedly, the accident will always happen at some time.

That is to say, as long as the possibility of accidents exists, no matter how small, accidents will happen sooner or later, which is the enlightenment of 100- 1=0.

It tells us that one (time) or several (times) hidden dangers (illegal acts) may not lead to accidents in the work of safety production, but in the repeated work, accidents will eventually occur. For a person, safety means health.

For a family, safety means harmony. For an enterprise, safety is development. For a country, security means strength.

Murphy's Law is a psychological effect. The main content is that nothing is as simple as it seems. Everything will take longer than you expected, and things that go wrong will always go wrong. If you are worried about something happening, it is more likely to happen. The simplest expression is that the more you are afraid of an accident, the more it will happen.

Murphy's theorem is widely used, which reveals a unique social and natural phenomenon. Its extreme expression is that if a bad thing is possible, no matter how unlikely it is, it will always happen and cause the greatest possible damage.

Murphy's law emphasizes nothing more than possible situations, and negative situations are bound to appear. If you want to avoid them, it is recommended to divide them into two steps:

The first step: analyze the negative factors that may affect the results;

The second part: guard against negative factors and make good preparations in advance. If the controllability is poor, then you can only look at luck.
