Early life 
Nonaka was born in Tokyo in 1935 and as a child he lived through the Japanese defeat during World War II. His nationalist spirit led him to believe that, in order to avoid further humiliation, Japan should adapt its technological and organizational skills. In 1958 Nonaka received his B.S. in political science of Waseda University and then he accepted a job in Fuji Electric where he initiated a management program. "Soon he was collaborating with the business school at Keio University to develop a management curriculum for companies all over Japan." In 1967 he moved to US where in 1968 he obtained an MBA and in 1972 a PhD in Business Administration both at University of California, Berkeley.

This article is considered to be the one of the roots of the Scrum development framework, one of the most used agile software development techniques.
The SECI Model
