The growing gap between those with technical literacy and those can be closed, in part, by explaining technical findings using stories. Those who make the greatest impact on our views and the way we do things are expert as using stories to illustrate their points. Dr. Klein has collected a career's worth of insights and illustrates them with compelling stories that make this an easy-to-read, easy-to-comprehend volume that will enable readers to apply the important arguments he shares. My own investigations into government acquisition and healthcare information technology are threaded with people's desires to "remove the artistry" from practice and replace it with standardization. Dr. Klein makes compelling, and what I hope are broadly accepted, arguments for growing, supporting and taking best advantage of expertise -- rather than remove the artistry, he shows the advantage of focusing instead on creating more artists. "Streetlights and Shadows" is a highly useful volume for program managers, systems and specialty engineers that, once picked up, is hard to put down.
