Bursts of rapid communication, followed by longer periods of silence, are telltale signs of successful teams according to Behavioural Scientist.
Burstiness is a signal that team members attend to and align their activities with one another. During a rapid-fire burst of communication, team members can get input necessary for their work and develop ideas. Conversely, during longer periods of silence everyone is presumably hard at work acting upon the ideas that were exchanged in the communication burst.
