Quite apart from the fact that this seriously overstates the technical capabilities of Al Queda (as Marcus Ranum points out in "The Myth of Homeland Security", cf. BKMYHLSC.RVW), the analogy seems to be seriously strained. Yourdon also notes that the book is intended as a lesson for system developers, as a reminder to provide for system continuity or soft failure. The strategic implications of 9/11 are supposedly discussed in chapter two, but instead we have random thoughts and unconvincing logic. The world of information technology has *not* embraced information security or business continuity, most of the national initiatives listed in the book have subsequently failed, and privacy has, rather surprisingly, enjoyed something of a resurgence in importance. (Oh, and Magic Lantern was *not* a virus, Ed.) A simplistic and limited overview of system security is given in chapter three, followed by vague opining about risk management in four. In chapter five Yourdon proves that he misunderstands emergent systems by confusing the rapid response capability that might be expected from a flat organizational structure with the unexpected and unforeseen behaviours that arise out of a large number of units governed by simple rules. In discussing resilience, in chapter six, there is a good presentation of the fragility of efficient systems, but this is not translated into practical advice. Yourdon's point about "good enough" software, from his "Rise and Resurrection of the American Programmer" (cf. BKRRAMPR.RVW), is reiterated in chapter seven, but the process remains unclear. His material about death march projects, from another book, is repeated in chapter eight, but any relation to the main theme of this book is a mystery. Chapter nine is not a conclusion, but a compilation of the summary points from each chapter through the book. Overall, the book has very little to say about system development, and not much of use to say about 9/11. copyright Robert M. Slade, 2003 BKBYTWRS.RVW 20031107
