How Can You Get Follow Through From Someone. Vocal and Nonverbal methods for getting what you want.
The Law of Consistency- People have an inherent need to perform in a manner consistent with how they see themselves and how they think others perceive them.
If you believe in the person's ability and success tell them. When you make a request, let him know you believe he is the kind of person who follows through. As you make a request,
“You are the kind of person who follows through.”
”You’ve always impressed me with the ability to…”
“I’ve always liked the fact that you…”
Do not say,
“I have some doubts you will be able to get this done on time.”
“I am anxious about you getting this done.”
“I know this will be a problem.”
This only provides and opportunity for them to make an excuse or back out.
Try instead
“You know, Sara, I really appreciate you helping me out.”
“I respect the fact that you’re the kind of person who follows through on things.”
