What is the tandem model from Schiller & Partners?

In the tandem model, we work as a temporary part of your team — not as external consultants from the outside. You get immediate capability while simultaneously building internal competence.

Especially suited for vacancies in key positions, transformation projects, or when internal know-how is missing. Typical duration: 3–12 months with gradual handover.


A fresh take on organizational challenges

Hidden Cost Factors

Opportunity Costs

During recruitment and onboarding, significant opportunity costs arise: projects get delayed, decisions are put off, and competitive advantages are lost. These costs are often underestimated but frequently amount to several times the actual salary.

Delay Costs

The average time to fill a leadership position is 4-6 months. During this time, direct costs arise from increased workload on other employees, slowed processes, and delayed strategic initiatives.

Economic Benefits of the Tandem Model

Expertise Bundling

The tandem model combines external expertise with internal organizational knowledge. This synergy leads to faster and more solid decisions that are both technically optimal and culturally fitting.

External Force + Internal "Politician"

While the external expert can act unburdened by internal dynamics, the internal partner ensures necessary acceptance and navigation through organizational political complexities. This eliminates typical resistance to external consultants.

"Mit Michaels Expertise wurde Delegation Poker zum Schlüssel für klare Führungsrollen und Vertrauen – ein echter Gewinn für unsere Transformation zur ‘Geteilten Führung’!"

Thomas Kopatz, Development Director communicode AG

"I have worked with Michael for a year now and it has been an exciting journey. He has a keen eye for quality and has an opinion about development as he comes from a development platform. He understands the complexity of problems, talks to the concerned people to convey the problem in an understandable manner and does a great job with prioritisation and negotiation. He keeps in great touch with the team and strives to ensure that tension and pressure does not affect the team in any manner. Thanks Michael!"

Dinesh Vasudevans Staff Software Developer

"Michael is a very stable person who is not scared to challenge his ideas and to leave his comfort zone for the sake of a product and the satisfaction of the users. He is a very inspiring colleague and is always eager to provide to his teammates the safe environment that will invite them to experiment and to find solutions as a team. Despite his highly technical expertise he is totally open and ready to discuss not only design propositions but also design oriented working methods (scenario writing, design studios, etc.). His talent to adapt defines very well the creativity, the dynamism and the very well-structured thinking of Michael."
