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).

• In the early 1990s the Scrum methodology was introduced into some companies f.ex by Ken Schwaber and it was for the first time called SCRUM by Jeff Sutherland, John Scumniotales, and Jeff McKenna.

• In 1995 Sutherland and Schwaber described Scrum and presented the results at OOPSLA in Austin.

• 2001 “Agile Software development with Scrum”-book written by Ken Schwaber and Mike Beedle.
