Step-by-step explanation:
The key design elements for service operations include both technology and task. Technology, which refers to computers, software, and computer peripherals, plays a crucial role in improving the efficiency and effectiveness of service operations. It enables automation, data analysis, and communication.
Task design, on the other hand, involves determining the sequence of activities, roles, and responsibilities needed to deliver the service. By carefully designing both the technology and tasks involved in service operations, organizations can enhance their service delivery and customer satisfaction.
So, the correct answer is option 3.
