Customer service is certainly a key part of the customer experience, however the customer experience is the organization and culmination of all customer service actions and how your customers experience them.
Customer experience is much more than customer service.
Customer experience includes all customer service actions; how one is greeted on the phone, the appearance of your building and facility, and the appearance of your team members, the usability of your product, or the efficiency and effectiveness of your services, just to name a few.
Think about it, you could receive great service from your server at a local restaurant, but if the hostess was rude and the kitchen staff could be heard banging dishes and yelling out obscenities, your customer experience is still going to be poor, no matter how good the service from the wait staff was.
Customer experience as a strategy
The customer experience is all about every customer service...
