    3. 3. We’re losing the relay race “The… ‘relay race’ approach to product development…may conflict with the goals of maximum speed and flexibility. Instead a holistic or ‘rugby’ approach—where a team tries to go the distance as a unit, passing the ball back and forth—may better serve today’s competitive requirements.” Hirotaka Takeuchi and Ikujiro Nonaka, “The New New Product Development Game”, Harvard Business Review, January 1986. Mountain Goat Software, LLC
    4. 4. Scrum in 100 words • Scrum is an agile process that allows us to focus on delivering the highest business value in the shortest time. • It allows us to rapidly and repeatedly inspect actual working software (every two weeks to one month). • The business sets the priorities. Teams self-organize to determine the best way to deliver the highest priority features. • Every two weeks to a month anyone can see real working software and decide to release it as is or continue to enhance it for another sprint. Mountain Goat Software, LLC
    5. 5. Scrum origins • • • • Jeff Sutherland • • Initial scrums at Easel Corp in 1993 IDX and 500+ people doing Scrum • • • ADM Scrum presented at OOPSLA 96 with Sutherland Author of three books on Scrum • Scrum patterns in PLOPD4 • Co-founded Scrum Alliance in 2002, initially within the Agile Alliance Ken Schwaber Mike Beedle Ken Schwaber and Mike Cohn Mountain Goat Software, LLC
