Had to read this for a class on Policy Analysis, was pleasantly surprised.
Bardach has a writing style that is easy to follow and uses relatively clear logic. The book gives the impression he is a seasoned policy analyst. This "Eightfold Path" guide to comparing and judging policy alternatives will give you an excellent base of (to be followed loosely) steps in which to approach problems in public, nonprofit sector policy as well as private organizations, although the focus is on the former two.
The author also gives you what you want to know, examples, ideas, and "semantic tricks" to thinking out any of the steps he outlines, for instance: semantic tips for deciding what criteria to judge alternatives (variations on a solution).
If, to give any negative critique of the book, the author dissassembles his method too much sometimes - which leaves you confused as to which step you are referring to. To give credit though, not all types of analysis (and if you read the book you will know) are straightforward "Identify Problem, Identify Alternatives to solve it, Identify criteria to rank alternatives, and then choose" and depend on the context, as well as those funding your "analysis" and work.
Further, to credit Bardach, there are many pointers as well in other problem areas which are helpful, such as general project management, or even ways of structuring final reports and recommendations.
All in all, this is a quick read which isn't padded with useless information, and isn't lacking in terms of advice and pointers, to the effect of having things such as appendices of "work governments do" useful to not just borrow ideas, but stimulate the thinking process.
This one makes it to my top shelf, at least.
