While making investments in BI analytics seems like a good idea, FDNY is strongly challenged in measuring its success. Officials may be able to cite statistics showing a reduction in the number of fires, but demonstrating that BI analytics tools were the reason behind that decrease may be difficult because it involves proving a negative—that something didn’t happen because of itsefforts. Go to the FDNY citywide statistics Web site at www.nyc.gov/html /fdny/html/stats/citywide.shtml. Use those statistics and a data visualization tool of your choice to see if you can discern any change in the number of fires since the BI analytics system was installed in 2014.
