Errors generally occur as the result of avoidable and unavoidable processes or actions. The simplest way to correct errors is to avoid them or to minimize their repercussions.
This applies equally to the correct use and regular care and maintenance of high-quality, service-proven tools.
Zero errors is an objective that requires each job to be performed without errors from the outset.
Errors due to unavoidable processes should be corrected as soon as they occur and not at the end of a process chain in which their repercussions may be multiplied several fold.
