Define Key Metrics and a Dashboard for the Product

Propose a KPI dashboard for {{product_name}} aligned to the company's primary objective '{{company_objective}}'. Provide: 1) a prioritized list of 8–12 metrics (definitions and calculation formulas) split into acquisition, activation, retention, revenue, referral; 2) recommended visualizations for each metric; 3) suggested default time windows and segmentation; 4) alert thresholds and guardrails; and 5) how to derive a North Star metric and a short explanation of why it fits the product.
