Customer Service is arguably the most important service to provide. As Tony Hsieh of Zappo's says, "Never outsource your core competency"- which in any business, regardless of the product, should include customer service. Regardless of whether the customer is an end user working with a device you support or a project manager implementing a program strategy for a large corporation, the interaction between the client & service provider speaks volumes on whether the business relationship will be successful & lasting. Focusing on customer service, in all aspects of any project I work on, is an essential part of my process.
