You made a plan and followed it. Or at least tried to. But you didn’t get the result you wanted. So, what now?

Go back to the plan. Reevaluate it. Break it apart. Look at each step in isolation. Look at it as a whole. What new information did you gather while following the plan? What assumptions did you make that turned out to be false? Where did you have difficulties following it?

Only once you’ve reevaluated the plan can you decide if the plan can be saved. Should you scrap the plan? Should you rerun the plan as is? Or, can you adjust the plan to make it work?

There’s a lot to be learned from failure. So learn.
