As shown in the illustration, many company programs have a common and serious flaw. The
data from each of the different elements of the program are stored separately. Our visual
metaphor shows that we have a number of filing cabinets in the company - some of them
holding medical data, some holding monitoring data, some holding data on hearing
protection usage. Yet, very few companies have actually related this data together such
that they can tell how well their program is doing, and also if the program is not
accomplishing what they had hoped, or most importantly, why that outcome is occurring.
