Process FMEA is conducted with cross functional team from Manufacturing, Product Process and Quality experts. Certain cases safety engineers, customer & supplier teams are also involved. PFMEA is conducted for assembly, as well as individual component level manufacturing process. Always, potential effects are identified considering target attributes such as noise, poor appearance, endangers of safety, loss of a primary function, performance etc. and their effects on next user-consequences, due to failure modes like unable to assemble, cannot tap or bore, endangers operator etc. Similarly Potential causes are also identified with respect to equipment such as tool wear, inadequate clamping,worn locator, broken tool, gauging out of calibration etc. and operator related errors like wrong part selected,incorrect tooling, incorrect feed or speed rate, mishandling, etc. Process Controls are suggested varying from preventive methods of operator training, SPC, inspection verification , work instructions, maintenance, error proof by design and detective methods such as functional test, visual inspection, gauging, final test, etc. Based on customer organization standards, each parameters are classified into key, fit or function, safety critical characteristics for control methodology.
