Customer service• Customer service is the provision of service to customers before, during and after a purchase.According to Turban et al. (2002), "Customer service is a series of activities designed to enhancethe level of customer satisfaction – that is, the feeling that a product or service has met thecustomer expectation."• The importance of customer service may vary by product or service, industry and customer. Theperception of success of such interactions will be dependent on employees "who can adjustthemselves to the personality of the guest," according to Micah Solomon. From the point of viewof an overall sales process engineering effort, customer service plays an important role in anorganizations ability to generate income and revenue. From that perspective, customer serviceshould be included as part of an overall approach to systematic improvement. A customer serviceexperience can change the entire perception a customer has of the organization.• Some have argued that the quality and level of customer service has decreased in recent years,and that this can be attributed to a lack of support or understanding at the executive and middlemanagement levels of a corporation and/or a customer service policy. To address this argument,many organizations have employed a variety of methods to improve their customer satisfactionlevels, and other key performance indicators (KPIs).• Contents [hide]•
