  • Customer Service (Mentioned in 18.7% Job Postings): Customer service is the provision of service to customers before, during and after a purchase. The perception of success of such interactions is dependent on employees "who can adjust themselves to the personality of the guest". Customer service concerns the priority an organization assigns to customer service relative to components such as product innovation and pricing. In this sense, an organization that values good customer service may spend more money in training employees than the average organization or may proactively interview customers for feedback. From the point of view of an overall sales process engineering effort, customer service plays an important role in an organization's ability to generate income and revenue. From that perspective, customer service should be included as part of an overall approach to systematic improvement. One good customer service experience can change the entire perception a customer holds towards the organization.
  • Consulting Services (Mentioned in 1.67% Job Postings): Consulting Services means the provision of expertise or strategic advice that is presented for consideration and decision-making.
  • Telemarketing (Mentioned in 1.12% Job Postings): Telemarketing (sometimes known as inside sales, or telesales in the UK and Ireland) is a method of direct marketing in which a salesperson solicits prospective customers to buy products or services, either over the phone or through a subsequent face to face or Web conferencing appointment scheduled during the call. Telemarketing can also include recorded sales pitches programmed to be played over the phone via automatic dialing. Telemarketing is defined as contacting, qualifying, and canvassing prospective customers using telecommunications devices such as telephone, fax, and internet. It does not include direct mail marketing.
