A B C of Failure - Proactive Manufacturing and Maintenance

[Umang Vidyarthi]

Hello covers,

I have come across this fine article by Winston Ledet, a consultant and workshop instructor on proactive manufacturing and maintenance. His study has concluded that all failures can be traced back to 'defects', forming the basic cause of all failures, which can be classified into three sources A, B, and C.

As a confirmed Demingite, I really take issue with the wording used by the author when he writes:

" Most people do not realize that the vast majority of defects are created by Care-less Work Habits and underestimate the significant impact that defects can have. People waste much of their time and energy on trying to prioritize a long list of failure repairs that should never have happened in the first place. People refuse to accept that they have Care-less Work Habits because they equate carelessness with irresponsibility. "

It does not make clear "work habits" (read "work instructions")

are created by management and adherence to those instructions is one of the subjects of internal audits and subsequent management reviews.

Therefore, the use of the word "people" instead of "managers" may mislead a casual reader into thinking workers, themselves, are responsible for anarchic conditions which lead to faulty preventive maintenance programs, when the truth is closer to "managers did not create a system of checks and balances and continual evaluation to assure the efficacy of their preventive maintenance programs."
