ratios

Ecological sustainability in production does not only cause a positive contribution to environmentalism, but also leads to a longterm improvement of the companies’ competitiveness. Due to a lack of transparency, many companies face difficulties rating their own resource efficiency. This article deals with the introduction of a ratio system, which allows companies to evaluate the efficiency concerning their usage of resources. This enables companies to enhance their consumption transparency. Besides, this article discusses the challenges of using ratio systems and the comparison of ratios in general.

On the track to lean production it is necessary to develop new ratios, which should not only show us ex post what worked well and bad on the shopfloor. They should also help us to monitor and to improve the process itself. Important issues thereby are the capability of the workers and the flexibility of the production. Prof. Syska for these purposes has developed a concept for a lean production-controlling with ratios which is based on three columns: on the one hand the of the market perceived performance, on the other hand the process factors an as the third column the powering factors which are necessary for the change process.
