Tools for Quality Mgmt
1. SPC，Statistical Process Control; 2. MSA，Measurement System Analysis; 3. FMEA，Failure Mode & Effect Analysis; 4. APQP，Advanced Product Quality Planning; 5. PPAP，Production Part Approval Process.
SPC: A process control tool applying mathematical statistics. SPC analyzes and evaluates the production process, discovers the signs of systematic factors, and takes measures to eliminate their effects, in order to maintain the process and quality under control.
MSA: a specially designed?experiment?with mathematical statistics and charts that analyzes the resolution and errors of the measuring system, in order to evaluate whether they fit the measured parameters, and to determine the main component of the errors of the measuring system.
FMEA: a sort of systematic activities that analyzes each procedure of the whole process and the subsystems and parts of the products at the product design stage and the process design stage, discovers all the potential failure modes, analyzes their possible consequences, and then takes the necessary measures in advance, in order to improve the quality and reliability of the products. Design FMEA and process FMEA are the most frequently used.
APQP: Advanced Product Quality Planning, a part of TS16949 Quality Management System. Product quality planning is a structured method with the purpose of ensuring all the required steps be completed on time by improving the connection with each person involved. Effective product quality planning depends on the top management’s commitment to customers’ satisfaction.
PPAP: Production part approval process, is one of 5 core tools required by ISO/TS quality management system applied in automobile industry. The main effect of PPAP is to ensure the quality ability in the production process can meet customers’ requirement by reviewing the multiple outputs of APQP and providing enough guarantee for customers. PPAP is a control program for the production parts, and also a quality management method.
