The fishbone diagram developed by Mariano Bernardez (2009a, 2009b) in the introductory article to this issue of "Performance Improvement Quarterly" depicts the origins and interrelationships of the models and approaches of many fields and researchers that have contributed to human performance technology (HPT) as it is used today. We can efficiently look into the evolution of our field, which is a helpful insight. But, I am sure most professionals would agree that looking backward is not going to predict or shape the future. Nevertheless, the eclectic underpinnings of HPT do help to define its strength. The manner in which it has evolved to date presents an indicator of its ability to adopt and adapt to the new and the proven. (Contains 4 figures.)
