As much as I appreciate the agile manifesto, your suggestion seems a little like teaching the fundamental axioms of mathematics and leaving it at that. Yes, those principles are useful, but it's a lot easier to reach practical conclusions with more specific guidance.

Yes, but this is establishing a whole new set of principles ("Communicate like a pro", "Be a chameleon", etc.) without coalescing them down in any way. It's one thing to talk about a principle and then give specifics examples of how to apply the principle, but this hasn't bothered to coalesc coherent principles.

To steal your analogy, this is like stating principles: "When a triangle has a multiple of 3 length and a multiple of 4 length next to a right angle, the remaining side is a multiple of 5." "When the hypotenuse is a multiple of 13 and a side near the right triangle is the same multiple of 5, the remaining side is the same multiple of 12." People get lost in a bunch of random examples when all you really need to solve for the sides of right triangles is the Pythagorean theorem. A few examples help, but if you don't relate them back to coherent principles they're pointless.
