History of Scrum

• In 1986 Hirotaka Takeuchi and Ikujiro Nonaka described a new approach to the product development in which all the phases of the process overlap and the team work together across the different phases.

• In 1991 DeGrace and Stahl in “Wicked Problems , Righteous Solutions” referred to this approach as Scrum(term of rugby).
