Support Macro A/B Test Framework

Design and evaluate A/B tests for support macros so teams can improve resolution quality, CSAT, and handle time without guessing which response style works best.

Prompt Template

You are a support operations specialist. Create an A/B testing framework for customer support macros so we can improve outcomes with evidence instead of opinions.

**Support channel:** [email, chat, helpdesk, in-app]
**Macro or workflow to test:** [refund response, bug acknowledgement, onboarding help, billing reply, etc.]
**Current problems:** [slow handle time, low CSAT, too robotic, poor resolution rate]
**Volume:** [tickets per week/month]
**Team size:** [number of agents]
**Support stack:** [Zendesk, Intercom, Help Scout, Gorgias, etc.]
**Metrics available:** [CSAT, first response time, reopen rate, resolution time, escalations]

Build:
1. **Hypothesis set** — what exactly we are testing and why
2. **Variant design** — control vs test macro, tone differences, structure differences, CTA differences
3. **Success metrics** — primary and guardrail metrics
4. **Experiment design** — sampling, randomization, duration, and segmentation
5. **QA checklist** — how to keep the test fair and safe for customers
6. **Analysis template** — how to interpret winners, mixed results, and no-result tests
7. **Rollout plan** — how to ship the winning macro and retrain the team
8. **Example macro variants** for the scenario provided

Example Output

# Macro Test: Billing Dispute First Response

Hypothesis

A more empathetic opening plus a clearer next step will improve CSAT without increasing average handle time.

Variants

- **Control:** direct policy explanation first

- **Variant B:** acknowledge frustration first, then policy, then next action

Metrics

- Primary: CSAT

- Secondary: one-touch resolution rate

- Guardrails: handle time, reopen rate, escalation rate

QA Checklist

- Use the same agent pool for both variants

- Restrict to English-language billing tickets

- Freeze policy wording so only tone and structure change

- Review 20 live tickets manually before expanding test

Readout Example

Variant B increased CSAT from 78% to 85% with no meaningful rise in handle time. Reopen rate dropped 2.1 points. Ship Variant B as new default.

Tips for Best Results

  • 💡Test one meaningful variable at a time, otherwise you will not know what caused the result.
  • 💡Use guardrail metrics so a macro does not improve CSAT while quietly increasing escalations or handle time.
  • 💡Keep policy content consistent across variants unless policy clarity is the thing being tested.
  • 💡Small support experiments compound. One better macro can affect thousands of tickets.
