We did some brainstorming for Cartier watch servicing and thought through and end traceability solution with RFID/nfc so customers could follow their watches through every step of the service process. A little like how some car mnfrs send customers pics of their cars in different stages of build.
Part of this was about brand experience and engagement, part of this was about traceability and chain of custody. At a basic level it was hoped that that chain of custody would give us new insights into operations. At a more advanced level those insights could turn into active algorithms to direct the right watches to the best suited watchmakers based on model, queue, service experience, avg service time, etc....
JLC, if you're reading I'm happy to help with service design for free in Q1 in exchange for getting my Duometre sorted and a tour of the manufacture π
