It all began with Genrich Altschuller: (1926 – 1998) In his study of hundreds of thousands of patents, Altschuller determined there are only about 1,500 basic problems.

Originally created to solve engineering and design problems, the 40 Principles of TRIZ are now being successfully applied to social issues and business dilemmas. Was Leonardo da Vinci instinctively using the 40 Answers of Genrich Altschuller’s TRIZ?
