Services

For Organizations. For Leaders.

You face the challenge of filling key roles with confidence, developing leadership teams, or preparing your organization for the future? I support you with tailored situation-specific solutions.

I.

For Organizations

Succession Planning

Validate internal and external potential to reduce risk and make succession decisions with confidence.

Succession is more than filling a position. I help you find sustainable solutions, identify potential and facilitate smooth transitions — with analytical precision and a deep understanding of your specific requirements.

Leadership Assessment

Independent assessments of leadership capability and cultural fit.

Gain a well-founded, independent assessment of the strengths, development areas and potential of your leaders. My goal: to identify development opportunities and inspire leaders to realize their full potential.

“Feedforward” Dialogue

Future-oriented development – feedback without judgement.

“Feedforward” explores future‑oriented behavioral options in a joint dialogue. Rather than evaluating the past, it provides orientation and shared understanding along a developmental journey. The emphasis is on what lies ahead.

Leadership SCRUM

The Algorithm of Change.

Imagine being able to precisely determine which behavioral changes would generate the greatest growth in your leadership competencies.

The Leadership SCRUM algorithm analyses 360° feedback data and translates it into precise, actionable behavioral priorities. The proposed behavioral changes are discussed in a 'feedforward' session and evaluated for relevance. It is not about judgment, but about future-oriented development.

How I Work

Fit before judgment.
Development before verdict.

In three decades at Egon Zehnder, I have learned: it is not about categorizing leaders as 'good' or 'bad', but about finding the right fit between person and role — and taking individual development potential into account.

As a development partner, I go beyond analysis and feedback. My aim is to create genuine motivation for sustainable change. My approach is based on partnership, respect and the conviction that leadership competence is an ongoing development process.

Alongside Evolvion Leadership Advisory, I continue to work as Senior Advisor with Egon Zehnder – combining entrepreneurial independence with the depth of a long-standing partnership.

Certified systemic coach (ARTOP, Berlin). I naturally subject myself to regular supervision.

Principles

Discretion above all else.

No name-dropping. Independence from large agency networks. A protected space for candid conversation.

Methodological expertise paired with sound judgment.

Proven methods, individually applied. No template, but tailored support.

Consistent forward focus.

Not looking back to judge, but shaping what lies ahead. Feedforward instead of feedback.

Leadership development is a journey

Analysis matters – momentum matters more.

I.

The Succession

A key position opens up. Is the internal solution ready? Can an outside perspective help identify development paths or alternatives? This decision shapes the next few years.

II.

The Mirror

You are successful, but honest feedback is drying up. To reach the next level, you need an independent sparring partner you can trust.

III.

The Stagnation

The leadership team functions, but no longer inspires. The impulse for real behavioral change and new dynamics is missing.

When your boss isn’t your fan anymore.
