In the past six months I've read a few books on crisis management and this is my favorite. Coombs put together a concise book that is well organized, easy to read, and brimming with useful information. He used the three-phase (pre-crisis, crisis, post-crisis) model as a foundation after comparing it with other more robust models.
Because this was published recently (2012), the examples were current and memorable. As much as I dig the Tylenol/cyanide case study, it's nice to learn from events that have happened in the past few years.
I originally purchased this as a required text for graduate school but have used it as much, if not more, at work in building a crisis management plan from scratch. For someone who needs a grip on the basics, this is an appropriate tool. For a person with extensive crisis management experience, it may fall short of expectations.
