Have a new pair of eyes take a look at it.
Either your own, after taking a break or sleeping on it.
Or someone else completely.
When you are disappearing into the project plan.
Have someone else review the plan.
When the lines of the process map are no longer connecting.
Walk through the process with someone else.
When you’ve been staring at the document for too long.
Ask someone else to proofread the document.
It will always come back better.
Then perhaps you could do it for someone else.
