If I have a goal of $40K revenue this month and I know some things to put in my Action Line of the model but I don’t know If that “action line” makes my Result of $40K inevitable, what do you do?

In other words, I know what to try to make $40K in sales but I don’t know for sure if that’s everything I’ll need to do or if there’s other things I haven’t uncovered yet.

But I want to make the R line inevitable within a certain time frame. Thoughts?
