I found it very helpful in the beginning to write out my training plans because it made me really think clearly about what I wanted, how I wanted to get there, and what the incremental steps along the way would look like. It helped me stay conscious of all the little different aspects that went into getting a final behavior, and just how much I was asking my dog to learn at once.
I don't use them anymore because I've internalized this stuff enough that I don't need to write it out at this point. But when I was still getting a handle on things, it was a huge help.
