Campbell proposes a "standard" one-page project status document that is used across all projects for all reporting. In essence, a good idea; in practise, maybe not so good.
There are several examples given in the book, virtually no two of them alike - each was customised to the particular example, losing the advantage of standardisation.
The template itself is both too detailed (far, far too much information on one page - one particular example would need an A0 plotter to be usable on one page) and not relevant enough (information that is relevant only at an overall project governance level is being dealt with in a progress report).
The concept itself is simple, and is portrayed in about a dozen pages, leaving the rest of the book as basically an awful lot of waffle and padding - generic PM stuff about building a team, instructions how to read the report, numerous examples which read more as an advert for the author's employer than useful case studies, and generally a very verbose attempt to pad out this slim, large-print book to justify this being a separate entity from his previous OPPM book.
All in all, hugely unimpressed - nice concept but poor execution.
