In the late 1990s’ Microsoft performed a survey among employees of how much time they spent looking for information. On average, they found that an employee used 2.5 hours a day (a little over 30%) just looking for information.
Since the late 1990s’ the amount of available information has been multiplied a couple of times, and it could be that the time employees spend looking for information has increased. Alternatively, the tools we use have greatly improved, and the time could have decreased.
Either way, I would like to know how much time, on average, an information worker spends looking for information. Are there any surveys made and are they publicly available to reference?
