Your Partner for Change

We are an international consultancy supporting clients in various industries in achieving the change they seek. Our core competencies include three themes: Empower Teams, Execute Plans and Evolve Organizations. We achieve sustainable change through participatory programmes, as we co-create success with our clients rather than presenting off-the-shelf solutions. Our approach is holistic, ensuring that people, process, culture and systems are in sync.

Our team helps you to master transformation fast, in a structured and sustainable manner. In a world with many disruptive forces, it is critical for an organization’s success to deal with change effectively. Digitalization, globalization and Industry 4.0 require companies to adapt quicker than ever to new market conditions in order to remain competitive. With our Change Management expertise you can rest assured that your change program will be implemented effectively.

Ein Brettspiel erwies sich als sehr nützlich für die Entwicklung unserer Fähigkeiten, bei denen die Spieler lernen, Entscheidungen zu treffen, die sich auf das Ergebnis auswirken. Sie unternehmen verschiedene Schritte, probieren neue Taktiken aus, machen häufig Fehler und ziehen die notwendigen Schlussfolgerungen. So lehren die besten Brettspiele unsere Mitarbeiter, Verantwortung für ihre Entscheidungen zu übernehmen und keine Angst zu haben, nach einer Niederlage wieder von vorne zu beginnen.

Die Verwendung von Brettspielen bei der Entwicklung von Arbeitnehmern besteht auch darin, dass die Mitarbeiter während des Spiels lernen, einen Schritt weiter zu denken. In diesem Fall sprechen wir über Strategiespiele. Ein Mensch unternimmt nicht nur gedankenlos Schritte, sondern analysiert die Informationen sorgfältig und vergleicht sie mit seinem Aktionsplan.

The difference is...

People, Process,
Culture and Systems in-sync

Hide and seek - déjà vu of my childhood in project management

When projects fail because ownership is not shared

Our Values

We are passionate about helping people and organisations to achieve the change they seek. Our organizational culture is shaped by this purpose and by our values.

Our values influence our thinking and daily behaviour. They are realistic, clearly stated, aspirational and universal to our group’s work. The values are used routinely in decision making, priority setting, and implementation of all aspects of our work.

To achieve this they are regularly communicated within all parts of the group and role modelled by leadership, employed and freelance consultants.

Our Code of Conduct serves as ethical guideline, is shared with our clients and is an integral part of our consulting engagements.

We measure ourselves regularly against the effectiveness of their implementation.


We believe, genius is in the idea. Impact, however, comes from action. Simon Sinek

Our consulting job does not stay at the conceptual level, but adds value to the client organisations by producing specific and measurable results that make a direct impact!


We demonstrate that complex problems need simple solutions.

The solutions that we provide are simple because in a dynamic world, where skill sets vary considerably, only simple solutions will get real results. It is much harder to provide clean and simple solutions but it is worth it!


Talent wins games, Teamwork wins Championships! We believe that one person alone cannot keep pace with the speed of innovation and change in todays disruptive environment.

Therefore we have a strong emphasis of team work, bringing together experts who complement each other.


New ideas come from diverse ways of seeing things. Diversity is more than any one gender, race, or ethnicity. It’s richly representative of all people, all backgrounds, and all perspectives. It is the entire human experience.

We want our Group to be a reflection of the world around us and strongly believe that our strength lies in differences, not in similarities.


Trusting relationships are not a matter of technique or tools but of character.

We demonstrate respect for others, trustworthiness, as well as personal and professional integrity. While our initiatives are pinpointed and time limited, the relationships with our clients are long term oriented.


We believe it’s not about us.

We are facilitators of change. Understanding that our clients know their business best and that they know what change will make the most impact within their mandate we work alongside them to unlock these ideas and turn them into positive change!
