I have drafted a letter for the customer explaining the reason for the lot code change (expanding facilities), the benefits (increased traceability for our product), and the breakdown of the new system. Sales is reviewing the letter; however, they are inquiring on the potentially negative reaction from our customers. I do not have any prior experience with such a large change and no experience with how the customer's may react. Does anyone have any insight on how this may go? We have the change date currently set for February 1st, 2015 ; however this is flexible. Is more notice needed? Our Supplier Quality Requirements state that notice be given to any changes in process, but no exact timeframe.
Appreciate any help!
