It doesn't matter what kind of business you're in. If you want to be successful, you need to have good customer service. Even if you're just one person working for a company, it's vital that you approach everything with the mindset of putting the customer first. Keeping this in mind is certain to ensure you work more efficiently and more professionally and have better outcomes whenever you interact with a customer.
One of the biggest problems IT professionals have is interacting with customers. You see, many have an abundance of training in technical skills and software. They're able to complete their jobs behind the computer screen well. However, once hired at a company, these people have trouble performing all of the necessary duties associated with their job. They don't teach you how to interact with customers in training courses, which is a real drawback since you'll need to do this on a daily basis once on the job.
So what can you do to improve your customer service skills? Honestly, the best thing you can do is to practice. Learn the system the company you work for uses and go over it until it's committed to memory. One of the biggest problems with customer service is when you're in a situation and don't know what to do. Either you've never learned or don't remember how to handle the situation. Honestly, it doesn't matter what the circumstances are. All that matters is that you've failed to handle the problem appropriately, leaving a customer unsatisfied.
Failing to handle a customer service situation properly in the moment can have a snowball effect. In fact, when you allow a customer to walk away from a situation less than happy, you give them an opportunity to let other people know about their experience. This can be considerably detrimental to a business since word of mouth is a powerful tool for good and for evil. Can you imagine what would happen if someone were to start tweeting about their negative experiences with the company? Word would spread fast. And to know that you had the opportunity to fix the problem before anyone got angry can weigh heavy on your head and your employer's.
Seriously, you need to be able to handle basic customer service needs as an IT professional. Otherwise, you'd bound to let down your employer and may find it difficult to get a job. So do your research, take a class, or read guidebooks. Do what it takes to round out your skill set and be a better employee.
