    %T "Systems Reliability and Failure Prevention"

    Chapter one is a very brief introduction: almost a preface. Basic
    statistical measures of failure and service are described in chapter
    two. "Organizational Causes of Failures," in chapter three, tells
    stories of some major disasters, but provides no structural
    recommendations. Chapter four looks at analytical approaches to
    failure prevention, covering the failure modes and effects analysis
    (FMEA) and fault tree analysis (FTA) methods that should be more
    widely used in general risk assessment. The discussion of testing
    types, purposes, and analysis, in chapter five, raises some very
    interesting questions: if a thousand versions of a part are tested for
    a thousand hours and only one fails, does this *really* support the
    vendor's assertion that the mean time between failures (MTBF) is a
    million hours--or is it equally possible that all of them start
    failing shortly after a thousand hours, and one failed early? Factors
    such as partitioning, involved in implementing redundancy in a system,
    are reviewed in chapter six. The material on software reliability, in
    chapter seven, is rather disappointing: there is still an evident
    hardware bias, little deliberation regarding the nature of software,
    and the techniques for stability are limited to UML (Universal
    Modeling Language) analysis, which is, itself, only suitable to
    object-oriented tasks. Chapter eight looks at the project life cycle,
    the preferred development models, reliability activities in various
    phases, testing, and reviews. In chapter nine Hecht addresses
    economic considerations in preventing versus accepting failures with a
    good deal of math: a more practical illustration is provided in
    chapter ten. Chapter eleven uses the techniques explained in the book
    in three example cases.

    For those involved in risk analysis and operation continuity work,
    this text is a tutorial for a number of engineering principles that
    are not widely discussed in the available literature. However, there
    are a multitude of topics that sound interesting and useful, but are
    not presented in sufficient detail to be useful to the non-engineering
    professional. For those in the field, the book will definitely be
    worth reading, but it probably could have provided much more
    assistance to those in the safety and security field.
