Have you tried using Jami Gold's beat sheets for plot outlining? They are great. http://jamigold.com/for-writers/worksheets-for-writers/
I have downloaded and used all of them to make sure my plot stays on track. Hope this helps! ;-)
This is great! Thanks! I recently I had to cut my plot down due to obnoxious length, and it will be good to go over this and make sure the important points still align.
To add to the conversation. I like to do a four act plot. Every act has an even length, which is good for the perfectionist in me. It's the same as a three act structure, but act two is cut in half, with the second half being when the bad guys close in. I also like the ending points of each act. End of act 1 is the point of no return for the MC, midpoint is a crisis that changes things up, and end of act three is the all hope is lost part.
