Moments-of-Truth
Computer Company Hotline
Figure 5.13
The technician was sincerely concerned and apologetic about my problem
He asked intelligent questions that allowed me to feel confident in his abilities
The technician offered various times to have work done to suit my schedule
Ways to avoid future problems were suggested
Experience Enhancers
Only one local number needs to be dialed
I never get a busy signal
I get a human being to answer my call quickly and he or she is pleasant and responsive to my problem
A timely resolution to my problem is offered
The technician is able to explain to me what I can expect to happen next
Standard Expectations
I had to call more than once to get through
A recording spoke to me rather than a person
While on hold, I get silence,and wonder if I am disconnected
The technician sounded like he was reading a form of routine questions
The technician sounded uninterested
I felt the technician rushed me
