Corporate Strategic Planning (CSP) reports on an important study of planning practices and the value of those practices. Though it is a long book, nearly 500 pages, one can get almost the full benefit by reading about 200 pages. In fact, CSP contains an excellent summary (Chapter 11) that is only 33 pages; this chapter should be sufficient for most readers. My review assesses what the book has to offer and provides a guide to the potential reader.
