Fair First Pass Yield Report (Fpy)
The First Pass Yield (FPY) report separates FAIRs by month according to the date each FAIR was most recently dispositioned. An FPY percentage is calculated for each month based on each FAIR's number of "Attempts," which equals the number of times a FAIR was dispositioned (approved, conditionally approved, or disapproved) by the customer.
"Attempts" is available as a column on the FAIR list pages ("View Internal" and "View Supplier"). Net-Inspect refreshes this value periodically, so you may need to wait for a brief period after a FAIR is dispositioned to see its number of Attempts go up. You can click the FAIR COMMENTS button on Form 1, located near the Customer field, to confirm the FAIR's submission and disposition history.
First Pass Yield Calculation
The percentage shown in each bar of the FPY chart is the percent of FAIRs that were approved that month by the customer after their first submission, out of all FAIRs that were dispositioned during that time period (You can see a list of these FAIRs by clicking the bar).
If 4 FAIRs were submitted and dispositioned in the month of November, and 3 of these FAIRs were disapproved at least once while 1 FAIR was approved after its first submission, then the FPY percentage for November will be:
1 / 4 = 25%
Note the percentage is the amount of FAIRs dispositioned in that time period, some of those FAIRs may not complete the buyoff until the next month but will only reflect the percentage for the month of first submission.
This means if 5 FAIRs were submitted on November 2 were approved on first submission, 2 were disapproved and re-submitted and approved, then the last was disapproved and not re-submitted until December, then FPY for November is 2 / 5, 40%.
The cumulative FPY line is calculated using the following formula
The number of first passed FAIRs for that month and all previous months in the given filter range divided by the total number of FAIRs for that month and all previous months given the set of filters.
If I have 2 FAIRs that pass in the first month and 4 bought off FAIRs total. Then in the second month displayed I have 5 FAIRs that were bought off on the first attempt and 9 FAIRs bought off total, we can calculate this:
The number of FAIRs First Passed:
2 + 5 = 7
The number of FAIRs bought-off:
4 + 9 = 13
Percentage displayed using the Cumulative line on month two:
7/12 = 53.8%
