Re: General analysis of CARs
Number overdue due CARs (trending and %)
Root Causes (graphic representation)
Effectivity/Follow up success/failures
In addition to what has already been said these are things I would want to see
yes, yes yes!
the purpose of corrective actions is to prevent reoccurance.
the so called "traditional" metrics of aging only promote huuried closure, not true study of causes and implementation of effective solutions. (thie is why we so often get the dreaded cause = operator error, corrective action = retrained operator, followed by disciplined operator, followed by fired operator). CAR owners can't perform a thoughtful investigation when the emphasis is on closign CARs quickly.
When I implemented the 3 metrics mentioned - and no others - I got great corrective actions and saw my repeat occurances fall to almost zero and I also got timely responses as managers began to see the benefit to yields, cycle times and cost as Problems went away...
This approach does require a CAR manger who understands good root cauase analysis for both variation based problems and error based problems. they need to be able to asses CARs when submitted for closure and be able to audit as followup to ensure that what looked good in analysis and verification testing worked in practice adn stuck. but it is worth the effort!
