If you want to know the experts in training course design, I suggest you classify the courses first. In other words, what kind of training courses do you need to design for which industry? Taking the manufacturing industry as an example, enterprise training courses cover a wide range of fields, such as human resources, marketing management, manufacturing, quality management, procurement management, and supervisor skills training. No teacher will be familiar with training courses in all fields. Another example is to design a training course for China Mobile, which will involve different kinds of business training such as key customer service, group customer development, business hall management and operation, outbound service, 10086 customer service hotline, operation and maintenance department and IT department. It will be more professional to design courses for the financial industry.
