Ken Schwaber & Jeff Sutherland created the Scrum Agile Framework based on The New New Product Development Game (TNNPDG) & empirical process control.
In the 20+ years since Scrum’s ascension, other useful methods – Flow, Theory of Constraints, Kanban and Lean Management have come to the forefront. In addition, while Scrum was designed for single product teams, Scrum is now being used in product teams that must collaborate with others as well as in IT organizations. In addition, empirical process control, a major tenet of Scrum, is not consistent with the systems-thinking or learning methods of Flow, Lean and ToC.
The “New Scrum Game” is the result of taking insights from TNNPDG and the aforementioned methods and creating a team-level framework that can be used for teams at any scale and both for product and IT. By going back to the source and incorporating new thinking (Flow, Lean) while discarding outdated thinking (empirical process control) a better Scrum is created.
This “New Scrum Game” already exists in the combination of Disciplined Agile Delivery and FLEX’s Team-Agility. It’s not a variation of Ken and Jeff’s Scrum, it’s simply a modern version of the Scrum Hirotaka Takeuchi and Ikujiro Nonaka (authors of TNNPDG) had in mind.
