Hi everybody
In measuring the CA effectiveness, I face some doubts, hope you can give some ideas.
E.g. it resulted a NC for poor performance in a process. Such process is monitored monthly.
The root cause was, a poor maintenance of a machine.
The action plans were to redefine maintenance frequency and hire a new guy with more competency.
Now the process runs fine, and maintenance is given correctly.
Next, is to evaluate the CA effectiveness.
Here I could define, if in the next month, the production is ok, I could close out the CA, and say it was effective, but if same problem happens again, it was not effective, then I have to do a new analysis.
But if I decide to measure it, that if in three months in a row, the problem is not happening, ok, it was effective.
But if in the first month the problem appears, it was not effective, for that , I have to do a new analysis.
Finally I'm lost, don't know what to define (how and when) to measure the effectiveness ,mainly what effect has the short and long term measurements, if it seems it doesn't make any difference when is not effective.
Please give some insights.
Thanks
