Lots Collected, Little Analyzed

• Collection without analysis has negative ROI

 

Most IoT data are not used currently. For example, only 1 percent of data from an oil rig with 30,000 sensors is examined.

-- McKinsey & Company

 

• As difficult as it is to collect and capture data,
  gaining insights via analysis takes just as much effort

 

• Dependable, real-world on-line analytics take time to develop, tune, and test.
