A/B Test Design

Design an A/B test for workflow improvement:

CURRENT WORKFLOW:
[Current approach]

PROPOSED CHANGE:
[What you want to test]

HYPOTHESIS:
[What you expect to happen]

A/B TEST DESIGN:
{
  "variants": {
    "control": "current workflow description",
    "treatment": "modified workflow description"
  },
  "split_strategy": {
    "ratio": "50/50 or other",
    "assignment_method": "how to split traffic"
  },
  "metrics": {
    "primary": "main success metric",
    "secondary": ["other metrics to track"],
    "guardrails": ["metrics that shouldn't get worse"]
  },
  "sample_size": {
    "minimum": number,
    "calculation": "how determined"
  },
  "duration": "how long to run",
  "success_criteria": "what constitutes a win"
}

IMPLEMENTATION:
- How to route to variants
- How to track which variant
- How to analyze results
