No prob.
Reviewing internal defect data for just a quarter would be considered insanity at the aviation maintenance facility I was at.
Our belief was that “trending over time” (week, month, year and multiple years) was just too valuable, and that was proven out over and over.....and yet, even with that level of granular analysis the swiss cheese model would STILL rear its ugly head occasionally.
The idea was to achieve zero defects through continuous process improvement......although obviously never achievable, striving for that target helped keep failures under control as much as possible.....at least that was the idea.
The most obvious weak link was that government employees are doing the maintenance. 😁
I work in electrical distribution.
Our weakness is we’re a monopoly.
