I am a fan of Slywotzky. I believe he is one of the best in the area of Strategy. This book, however, has been a real disappointment for me.
The argument in the book is that, in mature economies/markets, many firms have come to a point where growth by traditional means is no longer feasible. That is, firms have to think of means other than new product innovation, M&A, international expansion and pricing. The most clever route to growth, the authors say, is "demand innovation", i.e. to find out new revenue generation areas which were not thought of by your company or by your customers before. In order to do that, i.e. to create a new-generation demand, you must first consider your hidden assets and second analyze your customers. When you find areas of friction in your customers' processes and when you can use your hiden assets to improve those processes, you are into next-generation demand.
The idea sounds excellent. In fact, it is excellent. However the method suggested for working out new demand areas is not new at all. First of all, the hidden assets concepts is ver much like the "core competencies" as put forward by Hamel&Prahalad in "Competing for the Future". It is exactly the same theme. Moreover, eliminating the customers'/clients' frictions is also not a very new idea. You can find a much more elaborate and admirable version of this idea in McGrath&MacMillan's "The Entrepreneurial Mindset". This latter work is a million times better as regards the robustness of the methodology.
So, the whole book, in a nutshell, boils down to two suggestions:
1. Study your B2B client's internal processes and see if you can make them outsource some of their sub-processes to your company so that you "innovate" a revenue area which was not thought before (at least by you). So, "demand innovation" reduces to finding new areas for outsourcing, but from a sub-contractors' point of view.
2. Develop some of your core competencies to such levels of efficiency that you can conduct those services much more efficiently for your client than if they did it themselves.
The book has "few" detailed case studies for supporting these ideas. But only one or two are thought-provoking (Cardinal Health especially).
A good portion of the book is devoted to suggestions regarding corporate-culture for promoting next-generation demand thinking. What kind of a corporate culture, management approach and leadership structure are conducive to transforming your company into a demand-innovator? This portion is also about stating what is already known. There isn't anything novel and interesting.
There is a reference to a web-site of the book, claiming that there is considerable support stuff in there. However the material in the web-site is terribly shallow and looks more like a marketing gimmick to attract readers to MERCER web-site. In any case, if there is more useful stuff which is necessary, why not put them in the book in the first place?
In conclusion, I thought the book was not worth reading. It could be written in four or five pages, including the case studies. I could have read the above editorails and suffice with what was explained there. That is all you need. I wasted my time, you don't waste yours.
