We are an automotive supplier. When reviewing the AIAG PPAP blue book, section 3.1, there is a table that states some situations in which your customer would need to be notified. One of the examples that they give is a "change in test/inspection method - new technique". My question is, would changes in inspection frequency be considered a change in test/inspection method? For example, if we were checking something on on hourly basis and decided to move to once a shift, would the customer need to be notified?
