How do you decide there is a challenge to follow up on?
If somebody asks for a quote, you send the quote. They decide, or they stall. They sign. You do the work. You bill. You earn revenue.
If you're trying to gauge how well your business is doing and your only trigger to look more closely is on a revenue metric, then your alarm is wired to the end of the chain and you are essentially in a game of crack the whip, where you have little ability to influence the outcome.
If you also use quotes, which is an upstream indicator of revenue, you get more time to act.
In physics, position is where a thing is. Velocity is how fast it is moving. Acceleration is how fast that speed is changing. Jerk is how fast the acceleration is changing, and it is the first of the four to move.
The JERK framework helps you get an earlier indication within your earlier indicator, by moving from a position read to a deeper jerk read as your trigger for a conversation.
Two questions, not one. Which metric are you reading. And which level of it.
So which metrics and which levels of those metrics are you reading?
The JERK Report is a free weekly email that reads one business signal four ways: position, plus the three rates of change underneath it — velocity, acceleration, and jerk.
Most people track where things are. Almost nobody tracks how the change itself is changing. That’s the difference between reacting late and navigating early.
Each Monday, I take one real signal — hiring, pricing, AI adoption, customer demand — and read it through all four layers. Then I give you a five-minute practice to apply the same framework to your own business.
3 minutes to read. 5 minutes to use. A calmer way to see what’s coming.

Position — your car is stopped. You know where you are.
Velocity — you’re moving. You know how fast things are changing.
Acceleration — you’re merging onto the highway. The change itself is increasing.
Jerk — an 18-wheeler drifts into your lane. You have to change how fast you’re accelerating to get out of the way in time.
This isn’t just a metaphor. Your body reads jerk literally — when forces change too quickly, your muscles can’t adjust fast enough. That’s whiplash. Engineers design highway curves, elevator rides, and roller coaster loops with managed jerk limits so your body can keep up. NASA set jerk limits for the Hubble Space Telescope for the same reason.
Business works the same way. When your market shifts faster than your team, your cash flow, or your decision-making can adapt, you get whiplash. This report helps you sense the shift earlier.
Business owners, consultants, and operators with 10 to 200 employees who are making decisions about hiring, pricing, AI-driven change, demand signals, or trying to tell the difference between noise and trend.
Each Monday you get: one signal worth watching, the four-layer read in plain language, what it means for your business, and a five-minute practice you can apply that week.
During the dot-com era at Network Solutions (1999–2002), my colleagues and I tracked domain registration patterns through derivatives of change: position, velocity, and acceleration. It worked — the acceleration signal flagged the shift before most people saw it coming.
This year I added the third derivative — jerk — and it's become the one that matters most. It's the earliest signal in the chain: the moment something starts shifting underneath the surface, before the other numbers catch up.
The metaphor comes from Pacific Islander wayfinders, who crossed thousands of miles of open ocean by reading layers of signals — stars, birds, surface swells, deep currents you could only feel with eyes closed. Each layer saw further ahead. Each required a different kind of attention.
I'm writing a book about it. The JERK Report is the practice in public.
The JERK framework applies the four derivatives of motion from physics — position, velocity, acceleration, and jerk — to business signals. Position shows where things are. Velocity shows how fast they’re changing. Acceleration shows whether the change is speeding up or slowing down. Jerk reveals the earliest warning that an inflection point is approaching.
Jerk is the rate of change of acceleration — the third derivative of motion. In physics, it’s the force that causes whiplash: conditions changing faster than your body can adapt. In business, when jerk turns negative while other metrics still look healthy, it often signals an approaching inflection point.
Acceleration tells you change is speeding up. Jerk tells you the rate of acceleration itself is shifting — it’s the earliest signal in the chain. Engineers design highway curves, elevators, and the Hubble Space Telescope with jerk limits because systems need time to adapt. Sensing jerk early in your business gives you that time.

AEO (Answer Engine Optimization) monitoring is one application of the JERK framework. By tracking how AI engines surface your business over time and measuring the derivatives of that visibility, you can detect shifts before they become obvious.
