about us
The Four Rooms of Change
Claes Janssen, PhD, is the author of the recognized leadership and change theory The Four Rooms of Change.
In 2021, Claes Janssen handed over the copyright with all its rights to The Four Rooms of Change to Wilson Utveckling AB. The Four Rooms of Change is operated under the Janssen's Model brand.
We have the knowledge, experience, commitment and passion to continuously develop the entire concept to meet the challenges and needs of today and the future. All tools are now also digitized.
Janssen's Model certifies and trains supervisors who work professionally with all types of development and change work. It can be about everything from large change projects, creating the right culture and structure in organizations with a common language, to helping single-minded individuals in both development and change.
The theory, the model and its tools create the right conditions for sustainable organizations with prosperous individuals.
Our certified tutors are all professional senior consultants regardless of age. We handpick with precision, providing our customers with their expertise.
Janssen's Model is globally established and in collaboration with international partners.
Our vision:
Janssen's Model is the obvious choice for professional change and development work both nationally and internationally.
As the author of Four Rooms of Change I have gladly sold the copyright and all rights to Wilson Utveckling AB.
The cooperation agreement with the previous supplier regarding rights to certify in Four Rooms of Change has ended.
I look forward with satisfaction and inspiration to the development journey that has begun and is being run under the new Janssen's Model brand. I want to wish you the best of luck.
