When it comes to customer service, the obvious thing is to train only the customer service team in giving the best and most professional support to your clients. However, the most effective and successful companies have recognized that it's much more practical to train everybody in the business for proper customer service, from the top of the ranks, all the way down. Where this is becoming especially vital is in the IT department. IT professionals have an odd reputation for being extremely technically capable, but not as well trained in the customer service department as they could - and should - be.
The fact is that having satisfactory technical abilities is only half of providing proper assistance to customers both externally, and internally (to other team members). The other half of providing this assistance includes support, understanding, and cooperation so that customer satisfaction is the result.
Therefore, even if your customer service team is well versed in customer service methods and techniques, make sure that the rest of your teams are also privy to this information with the proper customer service training. This should include teaching each team member:
Customer issue resolution
The importance of customer satisfaction (for present and future reasons)
How to understand and adequately fulfill the expectations of customers
How to create rapport and build trust among customers so that you're working with them instead of "for" or "against" them in any given task.
Understanding cultural differences and how to handle diverse situations.
The main lesson overall should be to recognize that the entire mission of a business has to do with improving the ability to reliably and unfailingly bring the customers what they want and what they need.
Therefore, the real work required is in:
The process of friendliness to customers
The commitment of employees to bringing superior customer service
Excellence in dialog with customers.
Not only should each team member be taught this, but training should continue regularly. This means that your employees shouldn't just be trained in customer service when they join the team, but they should frequently have this training reinforced and updated to ensure that the information and practices remain fresh, and any new movements in customer service are applied in the best possible ways.
Customer service is the key to any successful business, so it is important that all of your team members are continuously familiar and comfortable with practicing these techniques and methods.
