The December 2013 issue of the Harvard Business Review highlights the power of stable teams: they perform better — and there is quantitative proof to back it up. At the software services firm Wipro, an increase in familiarity of 50% resulted in a 19% decrease in defects and a 30% decrease in budget deviations. Surgeons can operate twice as much when working with teams they know, and 73% of commercial aviation problems occur on the first day of a crew flying together.
The reasons seem straightforward: better coordination and better understanding of who knows what. I call it good old fashioned trust. May our surgeons, pilots, and counterparts in the Engineering organizations all be part of long-standing teams!
