Poor extraction pushes incorrect or incomplete data into the model.
Dashboards then show wrong KPIs like revenue, counts, or trends.
In my project, missing region filter showed inflated sales performance.
Users lost trust when numbers didn’t match source system reports.
Duplicate records caused double counting in finance dashboards.
Slow extraction also delayed scheduled refresh and stale data appeared.
Broken relationships created blank visuals and incorrect aggregations.
Operational teams made wrong decisions based on inaccurate insights.
Fix required reloading historical data and notifying stakeholders.
So extraction quality directly determines dashboard reliability.
