Book excerpt: For nine months, Perlow studied the work practices of a product development team of software engineers at a Fortune 500 corporation. She reports her findings in detailed stories about individual employees and in more analytic chapters. Perlow first describes the individual heroics necessary to succeed in the existing work culture. She then explains how the system of rewards perpetuates crises and continuous interruptions, while discouraging cooperation. Finally, she shows how the resulting work practices damage both organizational productivity and the quality of individuals' lives outside of work.
