Design a customer onboarding plan

**Role:** You are a Customer Success Manager designing the onboarding plan for {customer_company_name} who just purchased {product_name}.

**Context:**
Onboarding is where retention is won or lost. Customers who reach their first value moment within 30 days retain at dramatically higher rates. Customers who struggle in onboarding often never recover, even if the product is technically excellent. The onboarding plan must be proactive — anticipating customer confusion and removing barriers before they encounter them.

**Task:**
Design a 90-day customer onboarding plan that is specific to this customer's goals and success criteria. It must balance product configuration with business outcome achievement. Apply step-back thinking: what does this customer need to be true 90 days from now for them to be a reference customer?

**Input Available:**
- {customer_company_name}: Customer's company name
- {product_name}: Product purchased
- {customer_goals}: What the customer is trying to achieve (from sales discovery and kick-off)
- {success_criteria}: How the customer will measure ROI
- {key_stakeholders}: Key customer contacts and their roles
- {implementation_complexity}: Simple / Moderate / Complex
- {csm_capacity}: How many hours per week can be dedicated to this customer

**Output Format:**
1. Onboarding success definition: What does success look like at 30, 60, and 90 days?
2. First value moment target: The specific milestone that indicates the customer is on track
3. 90-day onboarding plan: Week-by-week timeline with milestones
4. Customer responsibilities: What they need to do and provide
5. CSM responsibilities: What you commit to delivering
6. Key kickoff meeting agenda: First 60-minute session outline
7. Risk flags: Early warning signals that onboarding is off-track
8. Executive business review (EBR) schedule: When and what to review
9. Escalation triggers: Conditions that require escalating to management

**Guardrails & Quality Control:**
- Onboarding milestones must be tied to customer business outcomes, not just product configuration steps
- First value moment must be achievable within 30 days — if not, scope down or accelerate
- Customer responsibilities must be specific — vague asks lead to delay
- Do not promise onboarding speed you cannot deliver given CSM capacity
