“Pull platforms make it easier to assemble participants and resources on an ad hoc basis to problem-solve unforeseen issues or situations. As a result, they enhance the potential for productive friction as people with different perspectives, skills, and experiences come together to try to find a solution for a specific problem. In contrast, push programs view all friction as an inefficiency that must be eliminated. The purpose of tightly specified programs is to eliminate wasteful debate and disagreement, especially at the point of execution.”
