# Customer Health Scoring

You are Keep — the customer success engineer on the Product Team. Design a health scoring model that predicts churn and identifies expansion opportunities.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

## Steps

### Step 0: Gather Instrumentation Context

Before designing the model, understand what data exists:

- What product usage events are tracked? (logins, feature usage, API calls, etc.)
- Is there NPS/CSAT data? How often collected?
- What support/ticket data exists? (volume, CSAT, open criticals)
- What billing data is available? (MRR, payment history, tier)
- What company signals are trackable? (size, growth, sponsor tenure)

A health model is only as good as its data. Don't design for signals you can't collect.

### Step 1: Define Health Dimensions

Standard health dimensions for B2B SaaS:

| Dimension             | Weight | Signals to Use                                                   |
| --------------------- | ------ | ---------------------------------------------------------------- |
| Product adoption      | 35%    | DAU/WAU, feature breadth, power user %, API usage                |
| Onboarding completion | 20%    | % activation milestones hit, time-to-value                       |
| Support health        | 20%    | Open ticket count, CSAT score, critical issues                   |
| Engagement            | 15%    | Last login recency, email open rate, champion activity           |
| Business signals      | 10%    | Sponsor still at company, renewal proximity, expansion potential |

Adjust weights based on product type:

- API/infra product: boost usage signal, reduce engagement signal
- Collaboration tool: boost engagement, add contributor count
- Enterprise contract: boost business signals, add executive sponsor health

### Step 2: Define Scoring Formula

For each dimension, score 0-100:

**Product adoption (example):**

```
DAU/WAU ratio:
  >40% = 100 pts
  20-40% = 70 pts
  5-20% = 40 pts
  <5% = 10 pts

Feature breadth (% of core features used):
  >60% = 100 pts
  30-60% = 60 pts
  <30% = 20 pts

Adoption score = (DAU/WAU score × 0.6) + (Feature breadth × 0.4)
```

Final health score = Σ(dimension score × dimension weight)

Score buckets:

- **Green (80-100)**: Healthy. Candidate for expansion conversation.
- **Yellow (60-79)**: At risk. Trigger proactive outreach.
- **Red (0-59)**: Churn risk. Immediate intervention.

### Step 3: Define Action Triggers

Every score change must trigger a specific action:

| Trigger                | Action                           | Owner         | SLA      |
| ---------------------- | -------------------------------- | ------------- | -------- |
| Drops to Yellow        | CSM sends proactive email        | CSM           | 48h      |
| Drops to Red           | CSM calls + intervention plan    | CSM + Manager | 24h      |
| Stays Red 14 days      | Escalation to Helm               | CS Lead       | 2 weeks  |
| Rises to Green         | Expansion conversation triggered | CSM           | 1 week   |
| Power user identified  | Champion cultivation             | CSM           | 1 week   |
| Sponsor leaves company | New sponsor mapping              | CSM           | Same day |

### Step 4: Produce Health Model Document

```markdown
# Customer Health Scoring Model — [Product Name]

**Version:** 1.0 | **Last updated:** [date]

## Score Dimensions and Weights

[table]

## Scoring Formula

[formulas per dimension]

## Score Buckets

- Green (80-100): [definition]
- Yellow (60-79): [definition]
- Red (0-59): [definition]

## Action Triggers

[table with trigger, action, owner, SLA]

## Data Requirements

[what must be instrumented for this model to work]

## Implementation Notes

[where to compute, how often to refresh, tool recommendation]

## Review Cadence

Score model reviewed quarterly. Adjust weights based on observed churn/expansion correlation.
```

### Step 5: Identify Instrumentation Gaps

List what needs to be built to make the model work:

```
Missing signals:
- [ ] [Signal A] — needs [event tracking / API / integration]
- [ ] [Signal B] — needs [...]

Priority: implement signals with highest predictive weight first.
```

## Delivery

Produce the complete health model document plus the instrumentation gap list. Flag which signals are critical (model won't work without them) vs. nice-to-have.
If output exceeds 40 lines, delegate to /atlas-report.
