Lean Interim International
Our Mission

Lean Interim is helping visionary leaders deliver what is important to them with greater value at greater speed.


What We do


Interim management

Since 2004, we have been enabling our customers leading change and business transformation. Our clients either have been signing a contract with Lean Interim to keep the internal headcount low or we have accepted temporary employment contract for an assignment to fulfill specific requirements and obligations for roles like being a Partner in a Big 4 Management Consulting Company or legally signing-off multi-million dollar deals as Interim CEO or Board Member.


Business Transformation Consulting & PM

With a track record of over 25 years, we advice on or initiate and lead Business Transformation Programmes.

In the 1990s, we were one of the driving forces and innovators that led to the New Economy boom. The Internet and especially e-commerce solutions have changed the needs of customers and thus the buying behavior sustainably. In order to meet these new customer requirements, it was suddenly necessary not only to react quickly to inquiries, but also to transform the entire organization from a hierarchical organizational structure into an efficient process organization. Today, almost 30 years later, we are still busy breaking down old silos in almost every mandate.

Since then, we’ve come a long way leading Digital Transformations and Cultural Transformations – including Lean SixSigma – to support our clients on their growth journey. We can offer a very deep expertise in transforming your operations and building new operating models. We break down historic silos and let the value, in form of services or products, flow towards your customers better and faster than your competition.


Capability Building - Teaching - Coaching

We are passionate about learning and teaching. We always assure that our methods, tools and maybe even a bit of our mind-set will remain within our clients. Outside Lean Interim, we initiated the Pixelpark Academy in Germany in 1999, the KPMG Academy in New Zealand and finally the Lean Interim Academy. We developed and implemented training programs in all kinds of organizations from small and mid-size TR Group and Condair Group to multi-billion dollar enterprises like Air New Zealand and Johnson & Johnson.

What My Clients Say?

I approached Dietmar after the CEO and I decided to tighten the Link between strategy and operations. Dietmar introduced us to Hoshin Kanri (Strategy Deployment), which we rolled out within three months. Dietmar helped us a lot to translate the strategy into the matrix and to communicate and explain the methodology to the organisation. Dietmar challenged us quite a lot on the way. He is the kind of consultant who tells you what you have to know, not what you want to hear - for the good of the organisation and always in a constructive and supportive way!

Dietmar was engaged prior to my arrival at Air New Zealand by our COO Bruce Parton to kickstart the lean transformation for Air New Zealand. Dietmar's deep competencies in business transformation and the tools and processes of lean, kaizen, collaborative problem solving, were evident throughout the professional engagement. A necessary step along our journey to world-class we are now building on these foundations by focusing on our wider continuous improvement culture and business model.
