7.Andon:

The Japanese origin term is the mixture of the two symbols 行(go) and 灯(light) that can be translated as "going where the light is". The andon is a luminous show activated in its technical application when a problem is found on a workstation to fix it as quickly as possible [45]. It can be caused by an operator or by the equipment where the problem happens automatically. To perform suitable activities, color codes may specify the form or degree of urgency of the anomaly. Initially, it was planned for large production workshops that are very important for visibility. It does, however, refer to other cases, such as call centres, and in its computerized form, in which warning lights can be displayed on the PCs (or mobile devices) of the persons concerned [46].
