What is Commitment Flow Architecture?
Commitment Flow Architecture is a conversion diagnostic framework for B2C growth. It treats conversion as a sequence of user commitments, not a single button, screen, or funnel metric. The point is to find which condition breaks before the user can make the next commitment: relevance, desire, trust, or ability.
A funnel is not a sequence of screens. It is a sequence of commitments. Every step asks the user to give something: attention, a click, an answer, an email, a date of birth, money, another month. Each ask has weight, each creates resistance, and each must be justified by the value the user expects back.
So the useful question is never how do we make this screen convert? It is: what commitment are we asking for, and what must be true for the user to make it?
Four conditions
At every ask, the user is silently running four checks.
Diagnose in that order and intervene at the earliest unmet condition. Adding social proof to a relevance problem, or removing friction from a desire problem, is the most common way teams burn a quarter: a correct mechanism applied to the wrong blocker. Three of these are gaps, closed by adding relevance, desire, or proof. The fourth is a gate, opened by removing whatever blocks completion.
One trap inside desire: a commitment fires when desire exceeds resistance: price, the comfort of the status quo, the pull of "later." Stated interest measures desire gross; conversion needs desire net. A desire problem is often a price problem wearing better clothes.
Two principles
Commitment Load Principle
The heavier the ask, the more relevance, desire, trust, and ease must be in place before it fires. Load does not change the four conditions; it sets the threshold each one must clear. The ladder, light to heavy: watch three more seconds, tap, answer a question, give an email, share sensitive data, enter payment, commit to a recurring plan, commit B2B budget.
When no intervention can reach the threshold, stop pushing and decompose: split one heavy ask into a sequence of lighter ones. An ask too heavy to make in one step is an ask that has not been broken into enough steps yet.
Data Proximity Principle
Funnel stage does not create relevance; data does. The strength of any message is how specifically it is anchored to what you know about this user, right now, bounded by one inequality: perceived helpfulness must exceed perceived intrusiveness.
"Hi Sarah, here is your offer" decorates. "You said your biggest challenge is starting conversations, but your answers show your stronger pattern is staying clear after the first reply" understands. The test for every personalized touch: would the user feel understood by this, or exposed?
How it assembles
Think of the four conditions as gauges. Load sets the redline each gauge must reach before the ask can fire. Data proximity is the main fuel; mechanisms are how you add it. The Playbook holds about forty of them, matched to the blocker. Decomposition is the escape valve when no amount of fuel reaches the redline.
Two rules govern the build: the minimum necessary intervention, where removal beats addition if removing something resolves the blocker, and every step earns its place. A step that does not add relevance, desire, or trust, reduce effort, collect data that sharpens a later step, or deliver value is friction.
What it is not
Not product strategy, pricing, brand, or research. It sits between them: analytics shows where users stop; this explains what to design next.
And it is falsifiable: the framework fails if its diagnosis and mechanism matching do not beat your team's prior experiment hit-rate. Most frameworks do not tell you how they would be wrong. This one does.
Two worked examples of this diagnostic in practice: where the ask gets heavy before the button and why ASO creative signal is not a store-page problem.
