A few years back, we were appalled to find that a person that was employed at a New York City agency since 1960’s had little or no tasks. The only spurt in activity came about once in a quarter when certain reports needed to be submitted to New York State. This person managed an antiquated software system that no one knew how to operate an obscure system that housed the data needed for funding.
There may be several reasons for sticking to an antiquated system for decades, but this demonstrates that if technology is not evaluated, and revamped, periodically, it will lead to increasing inefficiencies, particularly in mature organizations.
