Unscaling (Agile Denver 2014-08-25)

For those who couldn’t make it, my slides aren’t intended to tell the whole story on their own, but you may be able to get some value from them. The most common question I’m getting from people who see just the slides is about the source for the charts on pages 10-12.

The line chart is from J. Richard Hackman and is simply math—the number of unique links between individuals in a group of size N is N(N-1)/2. My stacked bar chart was an argument from that based on reason rather than an empirical argument. Given an exponentially increasing number of links, a non-zero coordination cost per link, and fixed capacity per person, at some point coordination overtakes other activities and continues to do so. This is one of those situations where collecting actual data is near impossible but where we can still reason about the shape of the curves. We can do things to move the inflection point of the curve, which is why there are no numbers, but the shape will stay the same.
