Process before action.
We don’t start with yoga classes and fruit baskets. We start with the question of whether your OHM has a process at all – and whether it is sustainable. Measures only make sense once the structure is in place.
Data instead of gut feeling.
Mental risk assessment, absence analysis, dashboarding: we work with figures that support decisions. With survey instruments that stand up to scientific scrutiny. And with reports that no OHM manager has to translate.
Friendly honesty.
We’ll tell you if your BGM concept isn’t working – but in a friendly way. We don’t follow the mainstream. We follow the evidence.

Our values.
Values are not created in a workshop. They are created in projects where things get difficult – when survey data reveals uncomfortable truths, when a client expects a different result to what the data reveals, when a recommendation triggers resistance. The following principles describe how we act in such situations and what we expect of ourselves.
- Scientific diligence: We justify our recommendations with evidence and name where the evidence base is thin. Although many measures are mainstream, they are not effective and we do not always follow the mainstream.
- Responsibility & integrity: Survey data, absenteeism patterns and interview transcripts affect the personal rights of employees. We treat this data with the necessary care and take responsibility for data security, data protection and the ethical handling of data.
- Effectiveness: What counts is whether something changes – in the stress structures, in management behavior, in absenteeism. Health days and fruit baskets are not an OHM strategy. We consistently focus our advice on tangible, sustainable improvements in working conditions, not on what is easy to communicate.
- Human dignity & respect: People are at the center of our work – not the key figure, not the case. This applies to employees in customer projects as well as to all people in our own teams and networks.
- Clarity & transparency: We translate complex scientific contexts into understandable language. We disclose our assumptions, state the limits of our methods and explain why we proceed as we do.
- Partnership at eye level: OHM does not function as an external service. It requires internal support, trust and the willingness to accept uncomfortable findings. We work with companies, not for them – as sparring partners who bring their own professional expertise to the table and represent it.
