The flywheel: the wheel that ties your loops together
The flywheel is the strategy that ties your loops into a wheel where each turn builds on the last. You learn to draw yours from facts about your business, to spot the doom loop, three ideas for getting started (the four fits, the cold start and infrequent purchases) and why it pays to run the loop by hand before you automate it.
What it solves
If you switch tactics every quarter and nothing adds up, this is where you pick one direction and see which part of your business pushes the next.
To get started
In Turning the Flywheel (2019), Jim Collins describes a heavy wheel: the first push barely moves it, but each turn builds on the last and momentum accumulates. A flywheel has four to six components, and each is an almost inevitable consequence of the one before.
The flywheel is the strategy. Loops are the measurable mechanisms that turn one or more of its components.
The opposite of a flywheel is what Collins calls the doom loop: push in one direction, stop, change course, push in another. Ads this month, a sales team the next, influencers the month after. Nothing builds.
