“The flywheel, when properly conceived and executed, creates both continuity and change. On the one hand, you need to stay with a flywheel long enough to get its full compounding effect. On the other hand, to keep the flywheel spinning, you need to continually renew, and improve each and every component.”…  “It must capture the sequence that ignites and accelerates momentum.” 

― Jim Collins, Turning the Flywheel: A Monograph to Accompany Good to Great
