In Beside the classic instruments used to solve quality problems, modern instruments were used to identify problems, respectively to determine the generating causes relations diagram and tree diagram; identification of solutions for arising situations; matrix diagram and the tree; elaboration of a problem-solving program based on proposed solutions decision-making diagram and arrow diagram (PERT).To signal and analyze nonconformities a heterogeneous group of people were asked to attend a meeting The problem was named and so were the pre supposed causes that generated it, in a similar manner with the brainstorming meeting, the main relations identified being cause-and-effect ones (Fig.6.).
