A weekly report built by hand
Harbour Logistics is a fictional operations business whose planning team merges carrier exports, warehouse records and customer updates into a weekly spreadsheet. Different reports use different meanings for dispatched and delivered. Meetings spend too much time reconciling figures and too little deciding what to do about exceptions.
Agree the definitions before the dashboard
The concept begins with a metric dictionary and a map of source systems. Each important field has an owner, a refresh expectation and a rule for late or corrected data. The first delivery focuses on a small set of measures used in an existing operational meeting. The team can explain each number back to its source.
Build an observable data path
The proposed Python ingestion jobs collect approved extracts into BigQuery. dbt models apply consistent definitions and automated quality checks. Looker views separate day-to-day exceptions from longer-term trends. Pipeline failures are visible, and a stale report is labelled rather than silently presenting an old figure as current.
Keep exceptions actionable
An operations view highlights a delayed shipment with the relevant time, source and accountable team. It avoids creating a second operational record where a source system already owns the action. Drill-through links take staff back to the right tool. Access controls ensure a customer-facing report cannot expose another customer’s activity.
Count the whole reporting effort
The illustrative twelve hours saved each week includes preparation and reconciliation time in the proposed scenario. A real evaluation would also include pipeline maintenance, quality review and the work required to resolve exceptions. The objective is a dependable decision rhythm, with less manual assembly and clearer ownership of the underlying data.
