My point is that I expect to see parenting advice regardless of whether or not it actually makes anything better. Similar things happen with nutrition - administrators of schools, prisons, and other facilities want to have an excuse for why they serve the food they serve. So, professional nutritional advice is given regardless of whether or not nutritionists have any idea what they&#x27;re doing.<p>Agile is probably in the same boat with management techniques. Nobody knows what works, and nobody wants to be blamed for doing things that don&#x27;t work, so there&#x27;s a booming market in &#x27;experts&#x27; that you can offload your judgment to.<p>Compare this with something like physics, writing, math, sales, or mixed martial arts. It&#x27;s much easier to tell what works and what doesn&#x27;t, so there&#x27;s both less room and less demand for bullshit peddlers.
