First, developers think they want windows and then they can’t handle the light. So the people with windows close them and then nobody gets to use the windows. And news flash, it can be really hot next to a window. Better to pull the desks back and put the walkways near the window.
Also when you have 9 key employees and 7 window seats you end up snubbing 2 people you wouldn’t want to live without. That shit is part of the calculus of turnover.
Far better to put little tables with three chairs by the windows. Someone can take a break, or have a quick tête-à-tête there. It’s everyone’s window.
