Sivasailam “Thiagi” Thiagarajan has been doing training for the past 92 years (including his last life time). He was elected president of the International Society for Performance Improvement (ISPI) twice, 25 years apart. He has also been the president of the North American Simulation and Gaming Association (NASAGA) five times. However, he has never been elected to any position at ASTD/ATD. As the Resident Mad Scientist of the Thiagi Group, he makes an almost decent living by playing games and helping others play games—to improve their performance.
