Which one of the following statements about the history of Scrum is NOT correct?
A . The idea of Scrum was derived from a “rugby” approach, in which “a team tries to go the distance as a unit, passing the ball back and forth.”
B . Takeuchi and Nonaka proposed that product development should be like a sequential relay race.
C . Scrum was based on a flexible and all-inclusive product development strategy where the development team works as a unit to reach a common goal.
D . Takeuchi and Nonaka based their approach on manufacturing case studies from various industries.

Answer: B

Explanation:

Takeuchi and Nonaka proposed that product development should not be like a sequential relay race, but

rather should be analogous to the game of rugby where the team works together, passing the ball back and forth as they move as a unit down the field. The rugby concept of a “Scrum” (where a group of players form together to restart the game) was introduced in this article to describe the authors’ proposal that product development should involve “moving the Scrum downfield”.
