(Choose the only one correct answer for each question. 2 point per question, total 10 points)Nike is the number one sports brand in the World. The market for sports shoes and garments(服装) is very competitive. Phil Knight (Founder and CEO) is often quoted as saying that ‘Business is war without b ullets.’The war is especially intense(激烈) in today’s economic declination. Over the past years, Nike has gained its success partly from the competency at research and development, as is evidenced by its evolving and innovative product range. However, the income of the business is still heavily dependent upon its share of the footwear market. Nike has no factories. It does not tie up cash in buildings and manufacturing workers. They then manufacture wherever they can produce high quality product at the lowest possible price. Interestingly, consumers that wear Nike product do not always buy it to participate in sport. Some would argue that in youth culture especially, Nike is a fashion(时尚) brand. Nike actively sponsors(赞助) activities such as the World Cup (soccer) and The Olympics to gain reputation in emerging markets such as China.1.

(10 points each question, total 20 points)3.What are differences between functional and divisional structures? Give an example for these two types ofbureaucratic structure.Functional structure refers to an organization in which similar and related occupational specialties are grouped together. (1 point)The strength lies in the advantages that accrue from work specialization. Results in economies of scale, minimizes duplication, satisfy employees etc. (2 points)but people tend to lose sight of the best interests of the organization as a whole; no one function is totally responsible for the results. (2 points)A company divides its department into accounting, hr, producing, marketing employed the functional structure. (2 point)Divisional structure is made up of self-contained units. (1 point)It focuses on results, frees the headquarters staff from being concerned with operating details; but the major disadvantage lies in the duplication of activities and resources. (2 points)Companies like GE and PepsiCo have the divisional structure. (1 point)4.What are Mintzberg’s managerial roles? Cite examples of activities managers you know would do whenperforming these roles.Interpersonal—roles consist of being the figurehead for the organization, assuming the leadership role, and acting as a liaison for the organization. Examples (3 points)Informational—roles consist of being a monitor of current information which is then dispersed to employees needing that information; also involves being the spokesperson for the organization.

Staff authority functions to support, assist, advise, and generally reduce some of the informational burdens of those with line authority.pare and contrast authority and power.●Authority comes from the position, not the person.●Power is the ability of an individual to influence decisions, which may not be reflected in their levelof authority. French and Raven suggested five bases of power: reward, coercive, legitimate, referent, and expert.●Authority is a two dimensional concept while the power is a three-dimensional one. One shouldmove up in the hierarchy to gain higher authority, but in order to be more powerful, managers could move up or move inward to have closer relationship with those people representing the power core.3.set an example to clarify each of five types of departmentalization that are available. Departmentalization types examples (departments in certain organization)Functional marketing, HR, R&D, financing etc.Product food, clothes, home appliances, etc.Customer personal clients, government, VIP etc.Geographic Great China, North America, EUProcess validation, registration, payment, etc.4.What is a matrix structure? What is its primary strength? What are its major disadvantages?●Matrix structure—an organization in which specialists from functional departments are assigned towork on one or more projects led by a project manager.●Primary strength—can facilitate coordination of a multiple set of complex and interdependentprojects, while still retaining the economies that result from keeping functional specialists groupedtogether.●Major disadvantages—creates confusion and has a propensity to sponsor power struggles.pare functional and divisional structure.Both are bureaucratic design of organizations.●Functional structure groups similar or related occupational specialties together. While divisionalstructure is self-contained, composed of autonomous units or divisions, with managers having fully responsibility for a product or service.●Advantages of functional structure accrue from work specialization. 1. putting like specialtiestogether results in economies of scale, minimizes duplication of personnel and equipment; 2. itmakes employees comfortable and satisfied since they have same interests.Chief advantage of divisional structure is that it focuses on results, also it frees the headquarters staff from operating details so that they can focus on long-term strategic planning.●Weaknesses of functional structure: organizational interests might be lost in pursuit of functionalgoals; no one function is totally responsible for results; members become insulated and have littleunderstanding about peers in other functions.The major disadvantage of divisional structure is the duplication of activities and resources.。
