Why companies don't learn from their mistakes

A study by economists from Friedrich-Schiller-Universitaet Jena found that three out of four customer complaints are not passed on to line managers, despite specific regulations in place. The researchers recommend training employees on the importance of forwarding complaints and developing incentives for their participation.
