Success is a measurement. Was business performance on target? Were Key Performance Indicators (KPI) acceptable? Was there business improvement or favorable business decision made as the result of data analysis? Was the analytical exercise smooth? Was the cost of performing data analysis acceptable? Is overall return on investment (ROI) in business intelligence acceptable?

What constitutes success can vary, but some common measurements usually exist. When implemented and used properly, BI  can bring out the best in businesses.
