There were similar tables at a large german corporation I worked for. These were basically agreed upon with the worker union for the different job levels. On paper it sounded good, because there seemed to be an exact definition on what the pay grade for the given job tasks should be.

However in reality nobody cared about this official tables. People were just promoted when there was money to promote anyone and when there was noone in line waiting for a promotion in front of them.
