A Jobs-to-be-Done framework Intercom uses heavily to understand why people do or don't switch products. Every switching decision is governed by competing forces: the pull of the new solution (attraction/differentiation), the push away from the current situation, versus the anxieties about the new thing and the inertia of current habits. Mapping these forces reveals not just why people buy, but the specific anxieties you must address to win them.
Origin
The Four Forces is a Jobs-to-be-Done framework; Adams credits working with Bob Moesta ('Bob West' in the transcript) and the JTBD school. Intercom adopted and still uses it heavily.
Core principles
- 01Switching is never a single force — it's competing forces pulling toward and away from change.
- 02The attraction of the new solution maps directly to differentiation ('what's different and better').
- 03Anxieties about the new solution are a distinct, addressable force — not just weak attraction.
- 04Surfacing and directly answering someone's specific anxieties can tip a decision.
- 05The framework explains real human decisions, not abstract personas.
How to run it
- 1
Map the pull toward the new solution
Identify what's attractive and better about the new option in ways the person actually cares about (the differentiation force).
- 2
Map the push from the current situation
Identify what about the person's current product or situation is pushing them to look for something new.
- 3
Surface the anxieties about switching
Elicit the specific fears and reasons the person might not adopt — the anxieties that hold them back.
Pro tip Talk to them directly (even informally) to draw out real anxieties rather than guessing.
- 4
Address the anxieties to tip the decision
Directly answer each anxiety and reduce the inertia of the current habit, shifting the balance of forces toward switching.
Pro tip Adams' own recruitment is the demo: Intercom's founders wrote out the four forces for him and fed him his anxieties over beers until he switched from Facebook.
In the wild
Intercom's co-founders Owen and Des used the four forces on Adams himself: they wrote out the forces for him joining, then over a few beers 'fed me my anxieties' and worked him through them, addressing each reason he might not switch from a job he loved.
→ Adams switched from Facebook to a ~10-person Intercom — he calls the tactic 'genius' and evidence of how well the four forces explain and drive decisions.
Common mistakes
Debating JTBD nuances instead of using it
Adams warns against spending energy on the peculiarities of one version of jobs-to-be-done — customers don't care; use the simple framework to build.
Treating anxiety as just weak attraction
Failing to surface and address specific switching anxieties as their own force leaves a strong pull unable to overcome inertia.
Is it for you?
Best for
Product, marketing and sales teams trying to understand why customers switch (or won't) and what specifically blocks them
Not ideal for
Teams that will get lost debating JTBD theory rather than acting; or decisions with no real switching cost or incumbent
From the transcript
“the four forces being like um different for people there's different forces when people try and switch product”
“wrote out the four forces for me to join and then secretly over a few beers talked to me and fed me my anxieties”
“it's just the four forces is incredibly good at um helping understand why people make decisions”
