Most reporting problems are not visualisation problems. They are questions of what is being measured, whether the underlying data supports the claim, and whether anyone acts on the result. DeepTeal starts there.
Areas of work
Business intelligence and reporting Designing reporting layers and dashboards around specific decisions, standardised so that numbers stay comparable across teams.
Data marts and analytical models Structuring data for analysis so that metrics stay consistent as the questions asked of them change.
Analysis and measurement Investigating a specific question properly, including whether the available data can answer it, and saying so when it cannot.
