Metrics in Lean – Part 6 – Productivity of a Quality Assurance department
Response to a question in the IndustryWeek manufacturing network on LinkedIn:
For metrics of quality itself, see Metrics in Lean- Part 2 , but you specifically asked about the productivity of your Quality Assurance (QA) department, meaning that you are interested in its efficiency rather than its effectiveness. It is a legitimate concern, as long as you don’t pursue efficiency at the expense of effectiveness, which is common but not in the best interest of the organization as a whole.

Hansgrohe uses Kanbans with RFID chips
See on Scoop.it – lean manufacturing
See on bathroomdesignideas.freeenergygeneration.net
The system has been used since 2008, and Hansgrohe provided the following pictures:
The cards are read when placed in the mailbox on the left.
It should be noted that this system does not eliminate the recirculating cards, but simply replace bar codes with RFID chips as a means of integrating the Kanban system with the company’s ERP system, for the advantages of richer and faster data collection. It does not eliminate the manual handling of cards, at least internally to the plant.
The next step would be to eliminate the cards, attach the RFID tags to part bins, install readers on racks, and implement the replenishment logic electronically. But the readers would have to be substantially smaller than those shown in the pictures.
