The Four Forces of Progress

Every switch is a tug-of-war. Two forces push a customer toward something new; two forces hold them back. When you can see all four, you can explain (and influence) almost any buying decision.

The Forces of Progress is the model we use to explain why customers do (and don’t) switch. We developed it to make the JTBD interview actionable. Once you’ve heard someone’s story, you map it onto four forces and the decision suddenly makes sense.

The equation of switching

A customer switches only when the forces pushing them forward outweigh the forces holding them back:

Push + Pull  >  Anxiety + Habit  →  the switch happens.

Flip that inequality and the customer stays put, no matter how good your product is. Most teams obsess over making their product more attractive (pull) while ignoring the two forces that actually kill most deals: anxiety and habit.

The two driving forces

1. Push of the situation

The push is the problem with the current situation. It’s the friction, frustration, or broken moment that makes someone start looking. No push, no search. People don’t change when things are merely okay; they change when the status quo becomes unacceptable. Strong JTBD interviews always locate the push first.

2. Pull of the new solution

The pull is the magnetism of the new way. It’s the vision of progress the customer can imagine for themselves. Notice this is not your feature list; it’s the better life the customer pictures. Marketing that sells the pull paints that picture vividly.

The two restraining forces

3. Anxiety of the new solution

Anxiety is the fear of the unknown: “What if it doesn’t work? What if I look foolish? What about my data?” Anxiety is the most underestimated force in business. You can’t feature your way past it. You reduce it with guarantees, social proof, onboarding, and removing risk from the decision.

4. Habit of the present

Habit is the comfortable inertia of what people already know and do. “It’s fine. I’m used to it. Switching is a hassle.” Habit is why great products lose to mediocre incumbents. Beating it usually means making the switch feel small and reversible.

Push and pull versus anxiety and habit

Here’s the strategic insight most teams miss: you have two objectives, not one. Increase push and pull, and decrease anxiety and habit. A product that’s only more attractive will still lose if the customer is anxious or comfortable. The fastest wins often come from removing anxiety and habit, the forces your competitors are ignoring too.

Forces in a real interview

The forces aren’t theory you apply later. You hear them live in a good interview. As a customer tells their story, you’ll catch the moment of push (“the old one finally died on me”), the pull (“I’d seen a friend using it”), the anxiety (“I wasn’t sure it’d be worth it”), and the habit (“I’d used the same thing for years”). Watch our real customer interviews and try to label each force as it appears.

Frequently asked questions

Who created the Forces of Progress?

Bob Moesta and Chris Spiek developed the four-forces model as part of the Jobs-to-be-Done interviewing method. It’s widely taught and frequently (mis)attributed; this is the source.

Are the four forces the same as a SWOT analysis?

No. SWOT analyzes a company. The four forces analyze a single customer’s decision to switch in a specific moment. It’s a model of demand, not of competitive position.

How do I use the forces in marketing?

Amplify push and pull in your messaging, and systematically dismantle anxiety and habit in your funnel with guarantees, proof, easy trials, and low-friction switching.
