Is the Rule Number of quality management?

In quality management, the numerical rule is called "Rule of ten".

Explanation:

Companies that provide goods and services have to guarantee the quality of their products. To do so, these products must be well planned, manufactured and tested before they are put on the market.

During the steps for producing and marketing a product -called a value chain- the rule of ten specifies that the cost of correcting errors is multiplied by a factor of ten as a step in the value chain is advanced.

In general terms, an error detected in the production-marketing chain of a product will be ten times more costly -and difficult to solve- the further one has advanced in this process, which is the principle of the rule of ten.
