The meaning of this word is pretty strange, having very little to do with the kanji meaning you learned. This word means to carry out a task. Maybe you can think of it like someone is saying "You (う) go do that task!" to get yourself to carry out a task. Whatever you do, just know this is a weird exception word, so you may have to do some extra work to remember it.
The reading is also a strange exception. You have to remember the おこな portion. Think of it this way: You have to carry out a task but you have to wait for the go-ahead to start. Then, your boss tells you "Okay now! (おこな) and you can begin.
The reading mnemonic isn't totally close to the actual reading, though, so be sure to make note in your mind that this mnemonic is only supposed to get you part of the way there. You'll have to get yourself the rest of the way for this one.
