It's normal, it's frustrating, it's unsustainable. So, at 11 and barring any developmental disabilities (which I assume you would have mentioned if they were a factor), he's plenty old enough to make choices about his own situation. That means choices that have consequences. He will not do things when you nag him, and there are few if any consequences because you are, basically, making sure he doesn't have any.
So, change it up. The shock alone will wake him up. At first, he'll think, "Oh great! She's off my case!" Shortly thereafter, he will see that his life really sucks when he makes certain choices. The first thing you have to do is to ask yourself, "What is the worst that could happen if Joey doesn't ____?" For example, what's the worst that could happen if he doesn't get ready for school? He's not going to flunk out, skip college or have the truant officer at the door, right? So for me (when my son didn't want to get ready), the worst was that I would have to drive him to school (when I felt like it) and check in at the office (where I told him he'd be explaining his reasons for later arrival to the principal since I wasn't about to lie or write a note), or he'd sit on his bed all day with no toys or TV or attention, or he'd go to work with me and sit in a corner on a hard chair with no video games and absolutely no opportunity to "help" my coworkers with even menial tasks.
If he doesn't pick up his laundry and put it in the hamper? Oh well, it's HIS CHOICE to not have his favorite shirt or clean underwear. Guess what? He goes to school in whatever is dirty or wrinkled. He will survive, you will not be labeled a "bad mom"!
He forgets his homework? Oh well, it's HIS CHOICE to stay after school for detention or extra help for what he missed. He forgets his lunch? Oh well, he can borrow money from a friend (and either dig into his savings or earn enough to pay it back by doing odd jobs for neighbors, not you) and buy a gross school lunch.
I'm sure there are chores that cannot wait - the garbage has to go out and the dog has to be walked. So, if you have to do those, do them silently and then be too tired or too far behind with your other chores to do what he wants or expects. If no dinner is made, oh well, his choice. If he can't get a ride to a friend's house, oh well, his choice. You can't take him out to buy a birthday gif for someone's party so now your child cannot attend, oh well (be sure to clue in the host parent that there's a problem, as a courtesy). Be sure you pick things that impact him - you staying up past midnight to get stuff done doesn't impact him at all.
The key to this is that he has made a choice. You are not a mean mom or a drill sergeant. You are a household manager and everyone has responsibilities. If he doesn't do his, you can't do yours. He has choices to not do things/ You have the consequences.
I would take the conversation out of it entirely. I think a written chore list on the back of his door or on the fridge is fine, or a calendar listing on the computer, but that's where your responsibility ends.
