Testimonials

Our ties to ROI go back 10 years, with intensive, very close collaboration. I value in particular the high degree of professional expertise and the great level of commitment shown by the consultants. This includes skill in getting matters implemented on the shop floor. 

Dr. Herbert Diess, Member of Board of Directors, Purchasing & Supplier Network, BMW AG

We set high demands for external consultants. Everything has to be a perfect fit here: from the know-how of the deployed consultants with regard to operational excellence, to the way in which they collaborate with the various project teams, to the fee model. ROI fully met our expectations.

Dr. Ing. Michael Mertin, Chairman of the Board of Directors, Jenoptik AG

ROI provided us with crucial support in redesigning PEP for the Systems for Rail Vehicles unit. This challenging consulting work requires extensive knowledge and, above all, a well-designed concept. That is the only way to identify improvements that will stand the test in practice. 

Dr. Albrecht Köhler, Member of Management, Knorr-Bremse SfS GmbH

We published a request for tender, and ROI won the bid! ROI clearly identified savings potentials, offered professionally reasoned proposals, and backed it up with a schedule.  

Dr. Kai Brüggemann, Head of Central Logistics, Airbus Hamburg

ROI’s extremely high level of expertise was apparent in the current project.

Manfred Webersdorfer, Head of Operations, TGW

Of particular importance to us is possessing extensive process know-how in the areas of supply chain management, production, and administration, as well as having marked expertise in implementation. The collaboration with ROI was excellent. 

DI Dr. Josef Doppler, Head of Management, Lohmann & Rauscher GmbH

Together with ROI, we were successful in achieving our project objectives in plant maintenance.

Dipl. Ing. Max Taferner, Project Head, RHI Refractories

Together, we undertook a strategically important project to redesign the way services are provided in our laboratories. ROI consultants understand how to structure processes and make them efficient, and they quickly fit in with the team. Particularly worthy of mention is the way knowledge gained from the manufacturing industry was successfully applied to the processes of a services company.

Joachim Birnthaler, CEO, TÜV SÜD Product Service GmbH, Munich

ROI is just the right partner for our company. We jumped into the methodology of manufacturing with both feet. This wouldn’t have been possible without the consultants' detailed know-how about tool manufacture and their multifaceted experience in production. Equally essential to the success of the project was that the consultants worked in a way that was collegial and open. As a result, the enthusiasm can be seen in the entire team, and not just in management.

Julia Esterer,Geschäftsführerin Dr.-Ing. Ulrich Esterer GmbH & Co. Fahrzeugbauten und
Anlagen KG

For us, ROI is a valuable external partner for introducing technical and organizational innovations and spotting trends at an early stage. For this reason, we're continuing to develop an ongoing collaboration.

Dr. Dr. h.c. Peter Mitterbauer, Member of the Board of Directors, Miba AG

ROI has become an important partner for the successful restructuring of business processes. The special quality of ROI lies in it being a blend of “implementer” and “strategizer", and it works so closely with the shop floor that synergies come about between the big players in the automotive sector and medium-sized companies operating worldwide, like Grohe.

Detlef Spigiel, Member of the Board of Directors, Grohe AG

During a very critical phase, ROI helped us to stabilize our production processes and to increase and permanently assure quality.
The close, collegial collaboration was a success and very enjoyable for all involved.

Ewald Klüe, Task Force Head, DB Fahrzeuginstandhaltung GmbH, Fulda

ROI supported us in realigning the way our company was organized. In particular, I value the pragmatic, expert, and collegial collaboration, as well as the extensive sector knowledge in the automotive and automotive supplier industry.

Jürgen Otto, Head of Management, Brose Fahrzeugteile GmbH & Co. KG

In collaborating with the committed ROI consultants, it quickly became apparent that we’d found the right partner. Together, we were able to achieve the set objectives – in spite of a tight schedule.

Dr. Wolfgang Hofmann, Manager, Fresenius Medical Care Nephrologica Deutschland
GmbH / Renal Pharma

Over many years of collaboration, we have come to know and appreciate ROI. One of ROI’s strengths lies in its process expertise, which comes from broad consulting know-how. ROI consultants are well trained and uncomplicated. Decisive for success is the savvy combination of process consulting and expert IT knowledge.

F. Peter Mitterbauer, Manager, Sales & Marketing, Miba Friction Group

One thing I particularly like about ROI is the emphasis on open communication and treating one another fairly. Likewise, the high degree of expertise and the professionalism of the consulting team.

Thomas Meixner, CIO, Miba Group

ROI took an already productive team and made it even better! The collaboration was a lot of fun!

Brendan McCarthy, Head of Assembly, BMW HamsHall

ROI brings methodology to a project. It doesn’t apply any pre-conceived solutions but instead systematically develops customized solutions.

Albert Sextl, Head of Plant Maintenance, BMW Leipzig

Word has now gotten out about ROI’s stellar know-how in the area of production optimization. With our bus manufacturing in Poland, we have successfully implemented proposals for improvement. For me, change management is important - communicating new ideas to employees, giving them a different perspective. Although that’s not always an easy task, the consultants delivered convincingly.

Martin Oetjen, Head of Management, MAN TRUCKS Sp. Z o.o., Poland

We are truly satisfied with the project results - with a reasonable amount of effort, a wide-ranging organizational change was well planned and implemented, making us more flexible and efficient.

Christian Wallstabe, Commercial Management / Managing Partner, Wallstabe & Schneider

In project work, ROI consultants quickly got into the details of operation and diligently saw to the development of a long-term approach. That made a believer of everyone.”

Thomas Langer, Project Head, Premium AEROTEC

The introduction of global standards on a best-practice basis was very well received by all involved. Employees around the world are on board with interest and great commitment. Communication between countries has improved decidedly.

Thomas Heckman, CEO, SiC Processing GmbH

In the project, we were convinced by ROI’s use of a combined top-down / bottom-up approach. The consultants were successful in taking the many ideas and creative proposals of the management team and our employees from various countries and giving them, above all, a clear, comprehensible structure in the best possible form. “Teasing out” and channeling the existing creative potential was a particularly important accomplishment of ROI.

Eckhard Gatawis, Head of Division Global Production, HOERBIGER Kompressortechnik Holding GmbH, Vienna

I was convinced by ROI’s approach. Our employees now have the professional know-how for developing and proposing their own solutions. Since the kickoff of the lean project, we’ve made a targeted decision to have the consulting team provide methodological support and thus laid the groundwork for the best possible start.

Dr. Stefan Stenzel, Assistant Head of Division and Head of the Optical Systems Unit,
Jenoptik AG

Our cooperation with ROI was very successful: not only will we recoup the project expenses in less than a year; I am also convinced that everyone involved has learnt a lot.

Stefan Schmidt, Head of Strategic Portfolio Management, KARL MAYER Textilmaschinenfabrik GmbH
