Few books on software project management have been as influential and timeless asThe Mythical Man‎-Month‎.‎ With a blend of software engineering facts and thought‎-provoking opinions‎,‎ Fred Brooks offers insight for anyone managing complex projects‎.‎ These essays draw from his experience as project manager for the IBM System/360 computer family and then for OS/360‎,‎ its massive software system‎.‎ Now‎,‎ 20 years after the initial publication of his book‎,‎ Brooks has revisited his original ideas and added new thoughts and advice‎,‎ both for readers already familiar with his work and for readers discovering it for the first time‎.‎ The added chapters contain ‎(‎1‎)‎ a crisp condensation of all the propositions asserted in the original book‎,‎ including Brooks‎'‎ central argument in The Mythical Man‎-Month‎:‎ that large programming projects suffer management problems different from small ones due to the division of labor‎;‎ that the conceptual integrity of the product is therefore critical‎;‎ and that it is difficult but possible to achieve this unity‎;‎ ‎(‎2‎)‎ Brooks‎'‎ view of these propositions a generation later‎;‎ ‎(‎3‎)‎ a reprint of his classic 1986 paper "No Silver Bullet"‎;‎ and ‎(‎4‎)‎ today‎'‎s thoughts on the 1986 assertion‎,‎ "There will be no silver bullet within ten years‎.‎"
