The Demand-Side Jobs to Be Done (JTBD) framework moves beyond "pain and gain" to focus on the context and outcomes that drive progress. It treats a purchase as a "hiring" decision made to solve a specific struggling moment.

The Four Forces of Progress

To understand why someone switches from an old way (Product A) to a new way (Product B), you must map the four competing forces.

• F1: The Push (Context/Struggling Moment): The specific situation making the current solution untenable. Without a push, there is no demand.
• F2: The Pull (Outcome/Solution): The vision of how the new product will make life better.
• F3: Anxiety (The New): Uncertainty about whether the new product will work or if it’s too difficult to learn.
• F4: Habit (The Present): Allegiance to the old way and the effort required to leave it behind.

The Equation of Change: (F1 + F2) must be greater than (F3 + F4) for a customer to switch.

The Discovery Process

1. Identify the Interviewees

Do not talk to people who "might" buy. Talk only to people who have recently made a choice.

• Recent Hires: People who bought your product in the last 30–90 days.
• Recent Churns: People who recently stopped using your product.
• Competitor Switches: People who recently moved from a competitor's product to another solution.

2. Conduct the "Interrogation" Interview

Treat the interview like a criminal investigation to reconstruct the timeline of the purchase.

• Discard the Discussion Guide: Don't ask a fixed list of questions. Follow the story.
• Find the "First Thought": When did they first realize things weren't working?
• Bracket the Story: Ask questions to narrow down the timeline (e.g., "Was it before or after the holidays?").
• Reach the "Edge of Language": When a user uses a vague word like "fast" or "easy," push them. Ask, "What did 'fast' look like in that moment?"
• Identify the "Fire" Criteria: Determine exactly what the user had to stop doing (fire) to start using your product (hire).

3. Map the Context vs. Outcome

Identify the "Irrational Rationality." If a user's behavior seems weird, you are missing the context.

• Context: "The stomach is growling, I missed lunch, and I have 3 hours of work left."
• Outcome: "Absorb stomach acid and get back to work immediately."
• Result: They hire a Snickers bar (meal replacement), not a Milky Way (emotional reward).

Examples

Example 1: Real Estate Downsizing

• Context: Retirees moving from 3,000 sq ft homes to 1,500 sq ft condos.
• The Struggle: They claimed they didn't want a dining room, but they wouldn't sign the contract.
• The Insight: The "Habit" force was the dining room table—it represented their family history. They wouldn't move because they didn't know where the table would go.
• Application: The builder added a specific space for the dining table (even if it crowded the room) and provided 2 years of storage.
• Output: Sales increased 22% by solving for the emotional friction rather than the floor plan.

Example 2: Software Marketplace (Zero-to-One)

• Context: A social media company noticed users transacting manually on their platform.
• The Research: They interviewed people who recently set up stores on eBay or Craigslist.
• The Forces: They identified the "Push" (Craigslist felt unsafe) and the "Anxiety" (eBay fees and shipping complexity).
• Application: They built a marketplace that leveraged existing social profiles to reduce safety anxiety and simplified local pickup to avoid shipping habits.

Common Pitfalls

• "Bitchin' ain't Switchin'": Do not build features just because users complain. People often complain about things they have no intention of changing. Only act on "struggling moments" that actually cause people to seek alternatives.
• The Conference Room Trap: Never hypothesize the "Job" in a meeting room. You will always be wrong. You must extract the "Job" from real-world stories of switchers.
• Overshooting the Job: Adding too many features can increase Force 3 (Anxiety). If a product becomes too complex, the customer may decide the "Habit" of their old, simple way is better.
• Focusing Only on Supply: Don't look at your product's technology. Look at the customer's life. A Snickers bar competes with a protein shake or a sandwich, not just other candy bars.
