Your Change Agents

Stefan Nüsperling, CEO

Stefan Profile

I help you to transform your organisation into a place where well-being prevails by giving you the tools and knowledge for facilitating positive change.

Businesses and markets nowadays are far more complex than before. Managers are faced with the generation gap, tough labour markets and globalization challenges.
By running over 100 workshops I have supported mid- and large-size companies, teams and managers to have a more attractive work culture, being more Agile and effective as well as having better communication and teamwork. In Japanese, this is called “Sanpoyoshi” (benefit for all three parties: Customer, Seller and Society).

Get in touch with me or book a Zoom call where I will give you a demo session of one of the tools of Management 3.0 which you can use immediately to increase collaboration in your organization.

As the first Management 3.0 facilitator in Japan, a co-owner of Management 3.0, a Lean Change Management, IC Agile certified facilitator as well as a Certified Scrum Master I have trained over 1.300 participants during my six years of running workshops. I helped my clients to become a facilitator themselves through additional training and consultation.

I am fluent in Japanese and am a regular speaker at conferences, for example, the Regional Scrum Gathering Tokyo, Scrum Fest Japan or the Management 3.0 Forward conference. Furthermore, I am part of the organizing committee of the Management 3.0 Conference 2020 and 2023 in Japan.
