Dr Errol Wirasinghe comes with over 30 years of experience in optimization, creative thinking, decision making, negotiating, and strategic planning. An Oil & Gas industry specialist and University Professor Wirasinghe has published papers on Management, Engineering and Economics. His paperback books include “The Art of Making Decisions”, “Better Defensible Decisions” and “Essential Negotiating Skills”. Dr Wirasinghe graduated as Valedictorian from Teesside University, U.K. and was awarded the prestigious CBI Scholarship to do his Ph.D.
He has carved out a niche as a “decision-maker” and a “creativethinker”, to shatter the myth and math of decision-making. Initially, this technique was used for deciding where to drill for oil, based on seismic studies from different locations. In 1990, Dr Wirasinghe adopted it for general applications.
