The “PDCA cycle” is something to turn, so please don’t call something that stops at “P” a “PDCA cycle. That is just “an organization that does not act.” Twitter

Subsequent development (PD, PDC, PDCA by @mogya)

  • P: Organizations that do not act
  • PD: An organization that never looks back
  • PDC: An organization with a broken heart
  • PDCA: Once Satisfied Organization
  • PDCAP: An organization that says, “Let’s make a perfect plan so we don’t fail this time,” but can’t do it a second time because the perfect plan is never completed.
  • PDDD: Organizations that have been doing things the way they were created a long time ago.
  • PCAPCA: Organizations that repeatedly discuss without executing
  • PDCP: Organizations that changed personnel and made new plans before reflecting the results of the checks

PDCAPD and going to the second D is the minimum requirement for the “PDCA cycle to be running. PDDD is not allowed, so it is important that the CAP is sandwiched in between until the second D. Some people have suggested that it would be better to start with D instead of P, and I think that’s possible, too, so.., I guess the difference between a good organization and a not-so-good one is whether it includes “D→CAP→D.”
