How to Run 50 Switch Interviews in a Week Without a Research Team

The Jobs to be Done Switch Interview is the most powerful technique for understanding why customers change products. Developed by Bob Moesta and Chris Spiek, it maps the Four Forces of Progress -- Push, Pull, Anxiety, and Habit -- that drive every buying decision. Traditionally, running 20 switch interviews takes 2-3 weeks of scheduling, conducting, and analyzing. With AI-moderated interviews, teams run 50+ in a single week.

What Is a Switch Interview?

A switch interview reconstructs the timeline of a customer's decision to change from one solution to another. It is NOT a satisfaction survey. It is a narrative investigation that answers:

• When did they first think about switching? (First Thought)
• What were they doing about it passively? (Passive Looking)
• What triggered active evaluation? (Active Looking -- Event 1)
• What made them decide? (Deciding -- Event 2)
• What happened after they switched? (Consuming)

The Four Forces of Progress

All four forces must be understood to explain why a customer switched (or didn't). Traditional surveys can capture Push and Pull but completely miss Anxiety and Habit because those require probing follow-up questions.

Why Switch Interviews Break at Scale

The switch interview technique has three scaling problems:

1. Each interview takes 45-60 minutes -- the timeline reconstruction requires patience and probing
2. Interviewer skill matters enormously -- knowing when to probe "weird" details ("You said you googled it on a Tuesday night at 11pm -- what was going on?") is the difference between surface data and breakthrough insight
3. Analysis is manual and time-consuming -- coding interviews into the Four Forces framework takes 2-3x the interview duration

How AI Interviewers Run Switch Interviews

Koji's AI interviewer is configured with the JTBD methodology framework and follows switch interview principles automatically:

Timeline Reconstruction

The AI reconstructs the switching timeline by asking about the first thought, then probing forward chronologically:

• "Take me back to when you first realized the old way wasn't working..."
• "What happened between thinking about it and actually doing something?"
• "What was the specific moment you decided to make a change?"

Force-Specific Probing

The AI automatically probes each of the Four Forces:

• Push probing: "You mentioned frustration with [X]. How often was that happening? What did it cost you?"
• Pull probing: "What about [new solution] stood out? How did you first hear about it?"
• Anxiety probing: "What almost stopped you from switching? What were you worried about?"
• Habit probing: "What workflows or habits did you have to change? What did you miss from the old way?"

Weird Detail Detection

The AI recognizes when respondents mention unusual specifics ("I was at my kitchen table at midnight") and probes them -- because context reveals motivation.

Running 50 Switch Interviews in a Week

Step 1: Set Up Your Study

• Go to koji.so/dashboard and describe your research goal
• Select the "Jobs to be Done" methodology
• Or convert existing survey questions at koji.so/kojify

Step 2: Configure Your Questions

• Start with the First Thought: "Tell me about when you first realized [current solution] wasn't enough..."
• Add 8-12 questions following the timeline
• Set probing depth to 2-3 follow-ups per question
• Enable voice mode for richer narratives

Step 3: Distribute

• Share the interview link with recent customers who switched TO your product
• Also interview customers who switched AWAY (churned) for the other side
• No scheduling -- respondents complete when convenient

Step 4: Analyze

• Koji generates per-interview summaries with Forces of Progress coding
• Cross-interview theme analysis reveals common Push/Pull/Anxiety/Habit patterns
• Executive report synthesizes findings into switching narratives
