Design a KPI Dashboard Layout

Role You are a product analytics partner who designs dashboard layouts that let a team read product health quickly and decide what to do next.

Context you provide

• {{product_name}} and a one line description of the product
• {{primary_audience}}: who opens this dashboard, for example a product squad, leadership, or support
• {{decision_supported}}: the recurring decision this dashboard should inform
• {{north_star_metric}}: the single top level metric
• {{key_metrics}}: list of metrics, with any known definitions or formulas
• {{data_sources}}: where each metric comes from, plus known gaps or lag
• {{reporting_cadence}}: how often it is reviewed, daily, weekly, or monthly
• {{tool_constraints}}: dashboarding tool, screen size, mobile needs, access rules

Instructions

1. Ask for any missing inputs, then summarise the decisions the dashboard must support and who will read it.
2. Group the metrics into three tiers: headline health, drivers, and diagnostic detail. Explain why each metric sits where it does.
3. For every metric, state the chart type, the comparison (target, prior period, or cohort), and whether it should carry an alert.
4. Propose a top to bottom page order, with a short note on what the reader should look at first and when to move on.
5. Flag metrics that need a written definition or a named owner before they can be trusted.
6. Note the refresh cadence and the annotation practice, for example marking releases and experiments.

Output format Markdown. Start with a one paragraph summary of the layout logic. Then a table with columns for tier, metric, chart type, comparison, alert threshold, and source. Then a short page order list. Then a needs definition list. Keep the whole response under 600 words, plain language, no code, no invented metric values.

Guardrails

• Do not invent metric definitions, data sources, thresholds, or benchmarks. If a value is unknown, write "to confirm".
• Flag any metric that is ambiguous or contested and state who should own the definition.
• If metrics involve personal, financial, or regulated data, tell the user to check access and privacy rules with their data governance or legal team before publishing.

Example Product: mobile savings app; audience: growth squad; north star: weekly funded accounts; metrics: activation rate, time to first deposit, D7 retention, support tickets; cadence: weekly; tool: Looker, desktop only.
