Tasks / Critical Mass
From the Wikipedia article -
As a simple example, consider a big city. If a person stops and looks up at the sky, nothing will happen. People nearby will go on about their business. If three people stop and look up at the sky, perhaps some people will momentarily turn around, but then continue on their way. But only a small number of people is required— say, 5 to 7 (depending on such factors as the culture, time of day, width of the street, etc) — to cause others to stop and look up at the sky, too. This number is called the "critical mass" or tipping point.
Do some experiments with regards to the Critical Masses. Collaboration is pretty much a necessity.
