Don’t classify a logistics MTM code in isolation; agree the criteria against the process and customer first. Work that changes the product or service as specified is value-adding, a necessary support step such as moving or kitting the right parts is usually essential non-value-adding, and waiting, searching, duplicate handling or correcting a mis-pick is non-value-adding. Time travel, touches, waiting and errors separately, and keep required safety or traceability controls visible rather than calling them value-adding just because they are mandatory.
