Earlier quoted context omitted.
The only people that screwed it up are the ones that monetized it. They made it a) rigid based on their definition b) defined themselves as experts in making teams agile based on their rigid definition c) charged for it PS. These same guys, once they couldn't squeeze anymore blood out of the Agile stone, moved onto a new marketing term, "craftsmanship". They now charge the same clients, even more money, to teach them…
Depends on who you're talking about here. Bob Martin one of the craftsmanship people, is very sincere in his desire to make the field better. I'm not sure about who's cropped up lately, though. Also, it's very, very rare for somebody to make a mint on a software book. I've talked with a number of authors, and their universal view is that writing code pays much better than writing a book. You do it because you have so…
Unfortunately, you can be totally sincere in your good intentions, and yet still repeatedly be wrong. When you are a high profile figure who presumes to advise others on the best ways to do their job, that makes you a liability.
It's a shame. Some of Bob Martin's earlier work exploring OO and the SOLID principles was quite decent stuff. But I think it's obvious at this point that he and several of his colleagues at Object Mentor have collectively lost the plot.
