Using TeleCenter System allows companies to have the correct number of people on duty at any given hour of the day or night, thereby optimizing the delivery of good service while holding costs as low as possible. TCS has an impressive list of customers, including American Express, British Airways, Sears, Amtrak, and Citicorp. TCS was planning a special two-day educational event, Customer-Forum, for its 300-plus customers, but was unsure how many TeleCenter System users would attend. Scheduled at the Opryland Hotel, the forum would offer speakers, workshops, and presentations. While TCS would underwrite the costs associated with planning the meeting and preparing the presentations, customers would be responsible for paying a fee to attend, as well as…
