However, it still remains concerns of what exact and practical strategies are in regard to the development of organizing vision, establishment of leadership style, implementation of education and training, and improvement of recruiting efficiency. These issues challenge professional managers of sales department. Therefore, in my study I conducted in-depth interview method to discuss the management strategies of excellent agencies in Nan-Shan Insurance Co., Ltd. in central Taiwan. Through interrelated data synthesizing and analyzing, successful management modes for management efficiency were found in these excellent agencies. Management strategies were sorted out from interview records and other case studies literature. The results showed that the image that professional managers devote themselves to prepare the pre-contest (sales quota contest) is very important. Different business titles of managers can also learn how to minimize management costs and raise management efficiency to its upmost value. Other methods to improve sales quota also include emerging task phases into organizing vision, setting up clear goals and awarding mechanism, and assisting sales representatives achieve goals with all-range of optimistic behaviors. In addition, important factors that may influence and improve high sales quota efficiency also include: unconventional reward policy, activity processing, education and training in morning briefings, cooperation of committee members, and quality of the staff to be recruited.
