During spring cleaning this week we were purging training materials more than twenty years old.  How many of these terms do you remember?

SPC,   Lean,  DMIAC,   Six Sigma,  TPS,  ISO9000,  Cost of Quality,  PPM,  VA,  Mistake Proofing,  Cp, Cpk, Ppk, AIAG, A2LA,  Run at Rate,  Control Charts,  DOE,  OEE,  Downtime,  Setup,  Cycle time,  Variation,  Quality Cost, DFM, Paynter Charts, Root Cause, Quality Circles, TOPS, AQP, APQP,s, PPAP, MSA, Gage R&R, Takt Time, Line Balancing, Kaizen Events, QFD, GD&T, Document Control, Critical Characteristics, Control Plans,s, TPM, OEE, Traceability
If you look closely at the above list it is comprised of two groups, quality tools, and quality programs.  It seems the tools remain over time and the programs tend to come and go.  If you look at the core tools many date back to the origins of the quality movement.
