Let me ask a few questions about the situation to help me analyze the problem:
YOU SAID: "Operating Characteristic curves show that the Pay Factor table overpays producers."
QUESTION (1): Am I right that the producers are contractors?
YOU SAID: "Most agencies define the acceptable quality level as 95 percent within limits, at which 100 percent pay is awarded."
QUESTION (2): What are the individual units that 95% of should be within limits at AQL?
QUESTION (3): Are the limits one-sided (either upper or lower) or two-sided (upper and lower)?
QUESTION (4): What is the unit of measure of the limits? (dollars, time, etc.)?
QUESTION (5): What is the population that the sample is taken from, and that the Pay Factor applies to?
YOU SAID: "Under these tables, 95 percent within limits pays on average 103 - 104 %."
QUESTION (6): Can you provide some information on who issues the tables and something that explains how PWL and Pay Factor tables are organized and how they are used in the calculation?
