Help needed on Action Line

I just had a wonderful 20 minute coaching call with Mimi. We worked backwards from my result line and she had me put 3 action lines – “stop”, “start”, and ?????. I did not write down the 3rd line and now I can’t remember how to label it. It was very helpful and I want to start using that in my own models. If anyone can help with the ??? I would appreciate it. I hope that makes sense.
