In the former camp, the people tend to like "Agile" because of the doctrine of writing code over doing planning. Often you will find PGMs/PMs who will write a story like "Make the site awesome!" with no other details. They usually want an estimate of how long that's going to take, but will refuse to add any more details -- because that's over-complicating the issue. They really just want to take credit for anything good that happened and punish people for anything bad that happened, all while doing absolutely no work. Usually they are actually deluded enough to think that their role is vital.
In the latter camp, usually there is a feeling that the programmers are stupid and this is why everything is in a complete mess. In order to fix things, they want to take control over everything and throw things over the wall at the programmers. Often the people in these camps used to be programmers (or may still think of themselves as programmers) and have always thought, "If only I could make everyone do what I want, then I can fix all the problems". So they spend their days dictating what everyone will do. It gets even more fun when similar people band together to form elite troops of specifiers -- that's where you get the endless meetings.
We've had this since programming in groups began. This is nothing to do with Agile. It wasn't any better at all before Agile. After Agile was introduced, nothing changed at all except now these guys have another name to incorrectly describe what they are doing.
My biggest problem with Agile is that it says nothing at all about how to accomplish the stated goals. That's why it is so attractive to people who don't have a useful methodology for producing software.
Do I want to continuously deliver software? Tick. Do I welcome changes to requirements? Tick. Do I want to deliver software frequently? Tick. Do I want business people working with software developers? Tick. Do I want motivated developers? Tick. Do I want to have face-to-face conversations? Tick. Do I want working software? Tick. Do I want to sustain a constant pace indefinitely? Tick. Do I want excellent software and design? Tick. Do I want simplicity? Tick. Do I want self organising teams (as long as "self" means myself)? Tick. Do I want the team to tune itself to get better? Tick.
Wow! I'm Agile! Whoo hoo! How do I accomplish the above? To quote someone I worked with in a previous job: "Most of this stuff is common sense. We're all the best in the industry and so this should be second nature to us. If anyone can't do these things then they really don't belong on this team". Now that's a strategy!
Mark my words: within the next 10 years there will be a new word for people to rally behind. At first it will make sense and some people will do cool things. But then the people who want to do nothing and the people who want to force others to do their bidding will grab the word and crush any meaning it ever had.
