Hello,

I just want to seek an advise from you guys about a study that I am working on.

I need to evaluate the effectiveness of preventive maintenance process using statistical tools in minitab.

Given data are the following:

1. Number of defectives for Assembly Line 1 per day

2. Number of defectives for Assembly Line 2 per day

3. Cumulative data counter at the time of a PM cycle

I have attached a sample data.

I am confused what statistical tool or graph to use to stratify the data (and perhaps to do a test?) and show how effective the PM cycle for Assembly Line 1 and 2.

Do you have any ideas using the given the data.

I tried P-chart but I am not sure if it is appropriate.

Thanks,

miongski
