Case Study

A plant and mechanical engineering company had to ensure its competitiveness. ROI-EFESO identified all the adjustment screws for the necessary changes at a production site in Germany and got the turnaround going with a multi-layered restructuring approach.

Case Study

Champions do not rest contentedly with their success, but always have their sights set on the next milestone. A technology group with around 20,000 employees at over 16 locations worldwide is also orienting itself in the direction of such a “North Star”. His starting points: an operational strategy and the initiatives derived from it, which should be implemented at every location in order to make them even more efficient.

Case Study

Cost transformation from premium to volume provider. Mass manufacturers who expand their Product portfolio into higher price segments are not uncommon. A premium manufacturer of refrigeration appliances, on the other hand, takes the opposite approach. What seems banal from a technological point of view is an enormous challenge from a cost perspective. ROI-EFESO accompanied the company in this demanding transformation project.

Case Study

The Italian group Marcolin S.p.A. has been designing, manufacturing and selling sunglasses and optical lenses for well-known brands such as Tom Ford, Bally, Moncler, Sportmax and Ermenegildo Zegna for 60 years. In 2018, she sold more than 14 million pairs of glasses through 150 distributors in 125 countries. Optimal management of the fashion company's international supply chains and production processes is correspondingly important.

Case Study

With hard targets for the entire operations area, a valve manufacturer is aligning a plant location for the future - and thus securing the site in Germany. Together with ROI-EFESO, the company restructures its manufacturing and logistics and achieves, among other things, an OEE of more than 85%.

Case Study

A dairy group identifies the topic of energy efficiency as a lever to cushion cost pressure from falling production volumes. The case study explains, how the company determines with ROI-EFESO suitable starting points for one of its plants. The potential of the measures in terms of possible energy savings, their CapEx and their amortization are specifically quantified.
