BI is the transformation of data into information grouped into usable sections. We collect thousands of bits of data from machinery, manual inputs and assumptions based on calculated guesses. This is done and stored into a data storage system that retains that data indefinitely. We then place a system to extract that data into groups that we can elate to and annalist the information.
Once the data becomes information we can then use it to compare with past, current, and future performances, this is now Business Intelligence.
