Quality

Review of 4M Conditions

In Step 5, we employ methods such as P-M Analysis, FMEA and design of experiments, to find ways of correcting deficiencies listed in the Deficiencies Chart at Step 4 that did not seem to have an obvious solution (where the conditions required for building in quality are hard to specify).…

Here, we identify any lapses in the 4-M conditions for each process as found in Step 3 and list them in a Deficiencies Chart. We then work out how to correct these deficiencies (see Table “Chart of Countermeasures for Deficiencies in the 4 Ms”). If the actions required to correct…

A QA matrix is a table that delineates how defects are being built into products under current conditions, in a process in which one wishes to assure quality.This matrix enables managers to see at a glance which processes are generating defects, which processes’ equipment and methods are faulty, and how…
