Learn English – Another word for someone who follows plans perfectly

single-word-requests

I mean to use the word in a good sense. To show that the person always adheres to the plans/strategies. Does not deviate even an inch.

I'm not looking for stickler or conformist nor do I mean to use the word in any disparaging way.

e.g. sentence – Joe knew that Michael would begin to see his point of view and he would have to agree to it, albeit reluctantly. After all, that had been the plan all along and he would stick to it. He was a phrase here all the way through.

Note – I'm ok with slang.
