For a company to be competitive today, one way is to create a natural feedback loop from the production department to the design department with information regarding the production systems ability to deliver a finished component.
The purpose with this feedback loop is to create respect for tolerances and to more design for manufacturing and assembly. The studied company in this thesis work developed a quality program to reach a spiral of continuous improvements to reduce cost of poor quality (CoPQ) and to reach an improved quality level (PPM).
The object of this work was to test and improve the quality program called The Zero Tolerance Program. Delimitations were made when the work was started and ongoing which led to that the impact on PPM could not be studied. The connection to CoPQ was difficult to obtain and could only be proved theoretically, not practically, due to the short timetable.
During the short amount of time the right root cause could not be found. The thesis work findings came to a number of identified Measurable Success Criteria and requirements which must be in place for the further progress of The Zero Tolerance Program.
