Sister Veronica Cornista, the Chief Executive Officer of the hospital for 8 years presented a rather bleak financial of the BOD. This according to her is the result of the declining occupancy rate which has affected the hospital’s revenues to such an extent that it ran a deficit for the first time last 1998. Such declines have not been unusual for this industry because of increasing competition. So far, the only response to these changes has been tightening of requirements for equipment or supply purchases.

- The director of social services of a county has learned that the state has mandated additional information requirements. This will place an additional burden on the agency. The director has identified three acceptable alternatives to handle the increased workload. One alternative is to reassign present staff members, the second is to hire and train two new workers, and the third is to redesign current practice so that workers can readily collect the information with little additional effort. An unknown factor is the caseload for the coming year when the new data will be collected on a trial basis. The estimated costs for various options and caseloads are shown in the following table: CASELOAD Moderate High Very High Reassign staff $ 80 * 90 95 New staff 70 70 70 Redesign collection 90 80 70 *Cost in $ thousands.

- Fast Burger Inc. is building a new restaurant near a college football stadium. The restaurant will be open 16 hours per day, 360 days per year. Managers have concluded that the restaurant should have the capacity to handle a peak hour demand of 120 customers.

Onsite processing is required for larger claims, while remote processing is done for smaller claims. (For onsite processing, assume—for simplicity—that the claimsprocessors use their own automobiles.) All claims will require that the customers’ records be updated.The claims processing center currently employs three full-time employees.
