goals of the ramp-up

For the economic control of production ramp-up processes established instruments such as milestones exist. Also, there are several approaches to the planning and control of the factors time, costs, and quality. Those approaches, however, are not sufficient for the optimisation of production ramp-up. Therefore in this article the authors present three questions that have not been solved yet. These are the aggregation of the goals of the ramp-up by an integral controlling, the definition of the contribution to the shareholder value, and the coordination of the companies involved in corporate networks.
