Business intelligence tools are more accessible than ever. Power BI licenses are inexpensive. Tableau is widely understood. Yet the majority of BI implementations we inherit from other agencies or build from scratch have the same problem: they produce dashboards that nobody uses.
The Root Causes Are Usually Structural
The most common failure is skipping the data model. A dashboard built directly on raw transactional tables will work in a demo but break under real usage. Slow queries, inconsistent numbers, and calculations that work in one context but not another all trace back to the same root cause: no proper semantic layer sitting between the raw data and the visualisation.
The second most common failure is building for the person who commissioned it rather than the person who will use it. Executive dashboards are designed in workshops with executives who then never open them. The people who actually need the data are analysts and operations managers who have completely different requirements and workflows.
The KPI Framework Problem
Many organisations start a BI project without a defined KPI framework. This means the dashboards get built around what data exists rather than what questions the business needs to answer. When the data does not align with the questions, the reports get ignored and people go back to spreadsheets.
The fix is straightforward but often skipped: run a KPI definition workshop before touching the data. Map each metric to a specific decision that needs to be made. If a metric does not support a decision, it does not belong in the report. This filters out 60-70% of the complexity before a single query is written.
What Good BI Looks Like
A well-built BI solution has a star schema or similar structured data model, clearly named measures with documented calculation logic, row-level security so users only see what they are authorised to see, and a self-service layer that lets business users answer their own follow-up questions without involving IT. These are not aspirational features. They are the minimum baseline for a solution that will survive 18 months of real use.
