Funnel Analysis Event Design

Design analytics events to track a conversion funnel.

FUNNEL: [Name of the funnel, e.g., "Signup Flow", "Purchase Flow"]
STEPS:
1. [Step 1: Screen/action name]
2. [Step 2: Screen/action name]
3. [Step 3: Screen/action name]
4. [Step 4: Screen/action name]

SUCCESS METRIC: [What counts as conversion]

For each funnel step, provide:
1. Entry event (user arrived at this step)
2. Completion event (user moved to next step)
3. Abandonment signals (user left without completing)
4. Error events (user tried but failed)
5. Parameters to segment by (user type, entry point, variant, etc.)

Also define:
- How to calculate drop-off rate between each step
- What properties to include for cohort analysis
- Any A/B test variant parameters
