in engineering terms 20% of the imput creates 80% of the output.
the same can be said for the throughput measurement of groups of people. work groups or sports teams or administrations.
it has been said that the distinction maybe as fine as 95/5 in some cases.
the anylitical question has always been; which 20%?
and the social question has always been; how do we support the other 80%?
the commercial question is how do we eliminate the other 80% (or more.)?
