- Professor Garcia has assigned 15 cases in his OM Seminarclass to be completed in a 15-week semester. The students, of course, are moaning and groaning that the caseload can-not possibly be completed in the time allotted. Professor Garcia sympathetically suggests that the students work in groups and learn to organize their work efficiently. Know-ing when a situation is hopeless, the students make a list of the tasks that have to be completed in preparing a case. These tasks are listed here, along with precedence require-ments and estimated time in days. Assuming students will work five days a week on this assignment, how many stu-dents should be assigned to each group, and what is the most efficient allocation of tasks? Can 15 cases be com-pleted in a semester? Explain your answer.arrow_forwardRoger Ginde is developing a program in supply chain management certification for managers.

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.
