Expertise
Some of you may be aware of the interesting research done by Dr. Anders Ericsson around the theme of "Acquisition of Expert Performance and Deliberate Practice" An important finding is that it normally takes 10,000 hours of practice to become expert in any discipline. Of course, I can imagine this would vary a lot depending on kind of practice and how it builds on your earlier skill. So I did some quick behind the napkin math: 1. Practice Required = 10,000 hours Assuming a concentrated effort to put at least 4 hours of practice into honing your expertise in your chosen field - the other being taken up by other information tasks (e.g. did you know a large part of the so called “information work” is actually searching for information? – fun fact I gathered while working on Enterprise Search ) 2. Time required to gain that expertise = 10,000/4 = 2500 days 3. Which makes it about 7 years to gain expertise in a discipline. Interesting!
