Weick's book may not be quite as topical as the more standard management guides of today but it is certainly a lot more insightful and quite useful in the long run. His focus is not on short term profitability or on efficiency gains but on a completely different field - namely on the long term survivability or viability of an organization.
In the book Weick describes practices and attitudes necessary for organizational resilience, such as mindfulness, the practice of not simplifying too quickly and of interpreting weak signals correctly and pairing them with appropriate (i.e. not too weak) responses, so as to prevent escalation.
It makes for refreshing reading and many of the case examples are quite enlightening - i.e. they are easy to communicate to management and should be graphic and salient enough to ensure at least a preliminary buy in. The book is also an easy and engaging read and can be easily devoured on a transcontinental flight.
What Weick does not manage to do, however, is to show a complete roadmap of how to deal with the standard obstacles on the way - i.e. it is a description of practices and attitudes of an organization, which has already achieved a high reliability / resilience status but as often, the trick lies in building one up from scratch.
In essence, a manager wishing to modify their organization according to Weick's principles will have a blueprint of a final result and its benefits (again, Weick could in principle make it easier by showing more numeric examples of the real benefit of using the approach, in spite of the initially higher costs associated with it) but will still need to blaze the trail towards it somewhat unsupported.
This comment is not to detract from the rating of the book, however - in essence, if one is not ready to invest the time and effort in analysing how to go about the task, it is unlikely that an attitude of 'mindfulness' has any lasting chance of spreading in that organization.
