I like this as a general guide to novel structure. However many resources I've read warn against getting too locked into a single script or pattern like this. Sometimes you need to save the climax for the last two pages, and sometimes you need the action to start on the first page (and fill in 'setup' stuff later).
Tthe opening scene has another important role, as well as hooking a reader. You need to set up the ending. “What?” I hear you cry. “That’s all backwards! I’m going to work up to my ending.” Well, yes. But also, no. A satisfying climax cannot just come out of the blue. Everything has to be foreshadowed, and a truly elegant novel will have given you all the clues right at the outset.
