SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Designing and validating experiments to determine the best-performing approach, ensuring statistically valid conclusions for marketing and product decisions. It provides a structured framework to plan tests, articulate hypotheses, select metrics, and document results for repeatable outcomes.

Core Features & Use Cases

  • Hypothesis-driven testing using A/B, A/B/n, MVT, and Split URL variations.
  • Sample size calculation, duration planning, and traffic allocation to ensure reliable results.
  • Metrics selection (primary, secondary, guardrails) and standardized result documentation.
  • Templates and guidance for end-to-end test planning, execution, and learning.

Quick Start

Define your hypothesis, calculate the required sample size, implement the variants, and start the test for the planned duration.

FAQPage Schema
How do I calculate the required sample size for an A/B test?▼

To calculate A/B test sample size, you need a clear baseline conversion rate, minimum detectable effect, and traffic allocation plan. This framework enforces pre-calculated sample sizes and test durations to ensure your experiment reaches statistically valid conclusions.

What metrics should I track when running A/B tests on marketing campaigns?▼

A/B testing for marketing campaigns requires defining primary metrics to measure success, secondary metrics for additional insight, and guardrail metrics to prevent negative impacts. This structured approach ensures you track measurable outcomes without degrading user experience.

How do I write a hypothesis for A/B testing product pages and onboarding flows?▼

Writing an A/B test hypothesis involves defining the expected change, the targeted audience, and the measurable outcome. This framework implements a structured hypothesis format for product pages and onboarding flows to validate specific feature changes.

When should I use multivariate testing instead of a standard A/B test?▼

Use multivariate testing when you need to analyze multiple variables simultaneously, whereas standard A/B tests compare one feature at a time. This framework supports A/B, A/B/n, and multivariate experiment designs based on your traffic and complexity requirements.

Can I run A/B/n tests with traffic allocation for different variants?▼

Yes, A/B/n tests support multiple variants with defined traffic allocation percentages. This framework calculates required sample sizes and enforces pre-set test durations to ensure each variant receives adequate traffic for statistically sound comparisons.

Why are my A/B test results inconsistent across different experiment runs?▼

Inconsistent A/B test results often stem from inadequate sample sizes, shortened test durations, or poorly defined guardrail metrics. This framework standardizes experiment design, enforces pre-set durations, and documents results to ensure repeatable outcomes.
