Activity-based costing? In CORAX all events are stored in the data warehouse. This also allows you to map the performance of all employees, or for each individual employee. For instance, what is the average lead time of a product, how much time does it take to process an order or to load a trip, how much VAS do you perform and for which customers; and much more other data with which CORAX allows you to allocate direct costs to the production process.
