Observations:

Initial FMEA yielded 17 improvement opportunities by RPN.

Chi-Square analysis allows for the acceptance of the Ha.

The log errors are dependent on the individual clerk.

Clerk B has the least errors and has the longest log time

with a log time mean

of 158 seconds.

Clerk D has 52% of all errors and the shortest log time

with a log time mean

of 120 seconds.

From the I and MR chart, Clerk D has a much wider

variation in log times than clerks B & BN.

From the Chi-Square analysis, Clerk D is 35.9% worse

than the statistical model predicted error rate.
