Use when asked to analyze a funnel, find where users drop off, diagnose low conversion or activation rates, design a metrics framework, set up OKRs, or measure whether a feature is working. Examples: "analyze our funnel", "why is activation low", "where are users dropping off", "design OKRs for this quarter", "is this feature working", "set up metrics for this launch".

Establish the full funnel from acquisition to habit. For each step, confirm:
If rates are unknown, note them as "baseline TBD" and flag: instrumentation needed before analysis.
Standard funnel template:
Step 1: Acquisition → [traffic source / signup page visit]
Step 2: Signup → [account created]
Step 3: Activation → [first value moment / "aha moment"]
Step 4: Habit → [returned within 7 days / core action repeated N times]
Step 5: Expansion → [upgraded / invited teammate / connected integration]
Step 6: Referral → [shared / invited / organic mention]
For each step transition, calculate:
Drop-off rate = 1 - (step N+1 users / step N users)
Rank transitions by absolute user loss (not just %). The biggest absolute drop is the highest-leverage fix.
Flag each drop-off with severity:
For each high-severity drop-off, run through the diagnostic checklist:
Acquisition → Signup:
Signup → Activation:
Activation → Habit:
Aggregate rates hide critical information. Segment the funnel by:
If segmented data is unavailable, flag it: "Aggregate rate masks channel-level differences — segmentation required before optimization decisions."
For the top 3 drop-off points, produce:
Drop-off: [Step N → Step N+1] — [X%] of users lost
Root cause hypothesis: [most likely explanation based on diagnostic]
Recommended fix: [specific change to product, copy, flow, or instrumentation]
Expected lift: [conservative estimate — e.g., "5–15% improvement in activation"]
How to validate: [A/B test design or leading indicator to watch]
Effort: [Low / Medium / High — engineering days estimate]
Present the funnel table, ranked drop-off list, and top 3 fix recommendations. Close with: the single change that would have the highest impact on the business metric that matters most right now.
