The tool is not the hard part
Most failed BI projects do not fail because of the tool. They fail because of messy data, unclear KPI definitions and dashboards that try to show everything. Success depends on:
- A clean, well-designed data model
- Agreed definitions for every KPI
- Dashboards designed around decisions, not data dumps
- Training and adoption so people actually use them
