About the Authors

chuck-schaefer-ltJeff-and-4TAChuck Schaefer and Jeff Evans met in the late 1980’s.  Chuck was an experienced OD Consultant and practitioner of SocioTechnical Systems design.  Jeff was working in training, OD, and Quality in manufacturing settings and was in his doctoral program.  Their common interests led them to working more together, until by the early 90’s they were working together as a small consultancy out of San Francisco California.  

They approached all of their projects as an action learning research project, documenting their assumptions, the research base, and their methodologies.  Then they ran reflective learning processes to understand what worked and what did not.  What followed was over a decade of work around the world in settings ranging from international company transformations to chemical plants.  After many experiments they learned what worked, then began to refine it.

In early 2000, they decided to expand on their personal guide to the methodology of creating high performing organizations and turn it into a book.  The Ten Tasks of Change emerged, with the intention of being something of a strategic guide to approaching this work.  It was published in 2001 through Jossey/Bass-Pfeiffer.  Jeff and Chuck continued to work together for years afterwards.

Chuck Schaefer


Chuck Schaefer was the director of Schaefer Associates and a senior professional in the fields of applied behavioral science and organization development. In his long time practice, he successfully guided leaders and their organizations through the development of strategic mission clarity and plans, organization restructuring, installation of high performance work systems, management team and work team design and development, critical business and human process improvement, and finding effective collaborative solutions to difficult organizational issues. He worked from a "human systems" perspective aimed at joint optimization of business goals, operating excellence and human quality of work life.

Basically, Chuck operated as a "process consultant" rather than as a business content specialist. He expertly guided people through the tasks of doing fundamental, candid action-research on themselves and their situation, supporting them in managing the human dynamics involved in taking a hard look at oneself and following through with what change is needed to succeed.

In addition to his organization and leadership consulting work, Chuck's professional experiences included time as a program manager and systems architect; university faculty appointments in behavioral science, organization, and management; and workshop leader in human potential development. As well as coaching executives and managers, Chuck guided the development of internal organization development personnel. His undergraduate studies were in aerospace engineering at the University of Illinois , and his graduate work was in applied behavioral science, high performance organization and humanistic psychology at the University of California , Los Angeles . He also had professional certifications in personal growth learning group leadership, large group interventions, application of NLP processes, and applied guided imagery.

Sadly, Chuck Schaefer passed away in 2013. He is greatly missed.
