And yet the author spends most of the article denying that these aspects of scrum are useful at all. Planning sessions are "highly inefficient," a "quick meeting between the architect and the developer" is better. What if someone else has an important piece of information that the dev and the architect don't? Maybe another dev on the team has done something similar in the past, and could have warned that the estimate was low? He won't be in that meeting, to avoid being "bored to tears" with a story he isn't working on.
So how do you know if Scrum isn’t right for you? If it’s hard. If it’s easy, then it will work for you.
Obviously, if something is hard, there can't be any possible benefit to it. It's so much easier to get rid of all that process stuff and just churn out code as fast as you can. What could possibly go wrong?
