More than 25 years of experience (see timeline) that previously produced such measurement tools as Spiral Dynamics and Management Drives.
Management Drives still sells and markets the same drives survey today as it did in 2000.
This company acquired the rights to the Piece of Cake tool in 1999 and built the product into what became Management Drives.
A few years later, in 1996, they wrote their standard work Spiral Dynamics and the movement of the same name was born. Still working under the Spiral Dynamics name is a very early computerized drives survey.
The Spiral Dynamics survey is essentially a “worldview” survey. It looks for the candidate's perceptions of his living world, and what the candidate sees as the ideal world. In this way a picture of sein and sollen emerges, and desired changes can be considered.
The Piece of Cake survey was deployed by different companies, including De Boer & Ritsema van Eck (DBR).
The collaboration between Koppenol and DBR was so successful that many multinationals in the Netherlands began using it and “foreigners” were regularly flown in to reinforce the values story.
In the Netherlands, Hans and Machiel Koppenol took note of the work of Clare W. Graves (1914-1986), the scientist who succeeded in distinguishing “values” and also defining them as statistically valid.
The Koppenol men saw the great utility of Graves' theory and were the first to try to map values of whole organizations.
To this end, they initially automated a simple Graves survey, but this immediately encountered content and practical problems. Graves' original question set did not suffice in the practice of organizations.
