Meeting expectations is good. Exceeding expectations is better.
The first step to delighting your customers is being there when they need you.
If you wait until you have to change, you may have waited too long.
Double-check your voice mail message. Listen to your on-hold words and music. Write welcoming scripts for your telephone team. Pay attention to the music in your office and lobby areas. Make sure what your customers hear sounds good.
Are you doing only what you must or doing all you can?
No one ever delighted a customer by being 'good enough'.
