Paul Barnhurst argues that waiting for perfect data slows decisions. Focus instead on the 80/20 rule: nail down how your business makes money, its key drivers, and payment flows. Once you understand volume, pricing, and product mix, the rest is just math.
You can't wait for full clarity. Bad data is everywhere. You have to say, okay, it's good enough, let's go forward.
Yeah, so I always start with the revenue modeling. So I use 80/20 rule. 80% of the model is covering from the revenue model. So once you have the assumptions for the revenue model, meaning how the business actually makes money, what the drivers are, who pays whom, how the cash moves, what are the revenue assumptions.
If you have a really good understanding of your volume, your pricing, your products, everything that goes into your revenue, the rest of it for the most part is math.
Yeah, exactly, exactly.
