fuck, man I gave up on trying to develop focus. There are all sorts of methods that never worked for me.
Here is what I do.
option 1) take on two tasks at a time and convince yourself you would rather be doing X instead of Y. That way in your brain you are "getting away with it"
option 2) dont fight it. When you get the flow, isolate and GSD. When you arent feeling it, do what you need to do.
Option 2 isnt always an available depending on your circumstances but it is my favorite becvause I am actually way more productive this way.
