I was saddened to hear that my friend and colleague Allan Drexler passed away recently. He was 88. In the 1980s, he and I co-developed the Drexler/Sibbet Team Performance Model® (Model) and the facilitative methods and tools connected with it. Without Allan we would not have this model. The depth of his field experience with teams, coupled with his deep understanding of group dynamics developed in sensitivity training work at National Training Labs, kept the work grounded in the real world of working teams.
