   Able Communications\n<\/p>\n

   Able Communications is a leading cable service provider in a metropolitan area. The new customer bill-
   \ning system has caused an increase in complaints. Zoe Valine, the office manager, asked you to investigate
   \nthe situation. After interviewing data entry operators and observing the online data input process, you
   \nare fairly certain that most errors occur when data is entered.\n<\/p>\n

   Tasks\n<\/p>\n

   \n
   1. \nWrite a brief memo to Zoe explaining the importance of data validation during the input
      \nprocess.\n<\/li>\n
   2. \nSuggest at least three specific data validation checks that might help reduce input errors.\n<\/li>\n
   3. \nWould a batch input system offer any advantages? Write a brief memo to Zoe stating your views.\n<\/li>\n
   4. \nSuppose that Able Communications is predicting 25% annual growth, on a current base of 90,000
      \ncustomers. If the growth pattern holds, how many customers will Able have in three years? If it
      \ntakes about 12 minutes to enter a new customer into the system, how many additional data entry
      \noperators will be needed to handle the growth next year? Assume that an operator works about
      \n2,000 hours per year. Also assume a 30% annual attrition rate for existing customers. <\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
