I have noticed i made a mistake in my work. I need to follow some steps (wich weren't real clear for me at the beginning of my PhD and my supervsior never said anything about them), and i just saw i made a mistake. I have defined those steps in the wrong order. Let's say i did step 4 **before** step 3. Which obviously changed the results I was getting (now that the order is correct, the results are really bad).

It is my supervisor role to check if i am doing the correct steps in my work? Check if my methodology is the correct one?
