Process approach to the quality system

What is the process principle of achieving quality? In simple terms, it is the consideration of actions to manufacture products as a continuous technological process, in which a lot of people participate - workers, each contributing their labor contribution to the product, and the overall result of the work depends on the contribution of all participants without exception. That is, we can say that the error in the work of even one participant in the process can seriously affect the overall result of the whole process and negate the efforts of all the other participants.
