To balance giving and accomplishing, carve out work-only periodsThe engineers could set aside windows during which they were not allowed to interrupt one another. After some trial and error, the team earmarked Tuesdays, Thursdays, and Fridays from 9 AM until noon for quiet time, leaving the rest of the week for collaborative work, including helping one another solve problems. Perlow found that the quiet time yielded above-average productivity for 65% of the engineers. Three months later the team launched the laser printer, right on schedule. It was only the second time in the history of the division that a product had launched without delays, and the vice president credited the quiet time as the reason.
