Query: Logical, yet lacking new ideas and impact

This book is about a critically important topic to many professionals.I basically like the structure of the book as outlined in the Introduction (pp. 7-8, hardcover edition). These points are not dramatically new, yet neatly outline three key precepts to embrace when stepping up to a higher position. And throughout the book are boxed lines of text that define terms or give tips in a usable sound-bite.Still, this is where my compliments stop for this particular book. Why? Most of the writing over-simplifies the disparity between the "conventional" and the "step-up" behavior options that it introduces, as if we are either one or the other. Vague recommendations don't get fleshed out and hints that sound more like platitudes take center stage.As a reader, I was left with the impression that these authors are seeing the real-world as a black-and-white kind of place.
