She knows there is a growing market for distinctive, quality cakes in thebakery sections of the supermarket chains, as well as in supplying independent individual premium cake shops, andalso for catering wholesalers supplying restaurants and hotels.Helen is very determined to set up her own business under the brand name of ‘Helen’s cakes’, and has bought someequipment – industrial food mixers, ovens, cake moulds – and also rented a small industrial unit to make the cakes.Helen has created three sets of recipes – one for the premium cake shop market, one for the supermarkets and onefor the catering wholesalers but is uncertain which market to enter first.

考题 3 Mark Howe, Managing Director of Auto Direct, is a victim of his own success. Mark has created an innovative wayof selling cars to the public which takes advantage of the greater freedom given to independent car distributors tomarket cars more aggressively within the European Union. This reduces the traditional control and interference of theautomobile manufacturers, some of whom own their distributors. He has opened a number of showrooms in theLondon region and by 2004 Auto Direct had 20 outlets in and around London. The concept is deceptively simple;Mark buys cars from wherever he can source them most cheaply and has access to all of the leading volume carmodels. He then concentrates on selling the cars to the public, leaving servicing and repair work to other specialistgarages. He offers a classic high volume/low margin business model.Mark now wants to develop this business model onto a national and eventually an international basis. His immediateplans are to grow the number of outlets by 50% each year for the next three years. Such growth will placeconsiderable strain on the existing organisation and staff. Each showroom has its own management team, salespersonnel and administration. Currently the 20 showrooms are grouped into a Northern and Southern Sales Divisionwith a small head office team for each division. Auto Direct now employs 250 people.Mark now needs to communicate the next three-year phase of the company’s ambitious growth plans to staff and isanxious to get an understanding of staff attitudes towards the company and its growth plans. He is aware that youare a consultant used to advising firms on the changes associated with rapid growth and the way to generate positivestaff attitudes to change.Required:(a) Using appropriate strategies for managing change provide Mark with a brief report on how he can best createa positive staff response to the proposed growth plans.

考题 单选题A brand of cough syrup comes with a measuring cup attached so that customers can measure the proper dosage. A consultant has pointed out that this cup is unnecessary, since most customers have measuring cups at home. Since the cups increase the cost of packaging the cough syrup and reduce the total number of units that can be shipped in a standard package, the consultant advises that the company can increase its net revenue on this product (total revenue minus total costs) by selling the cough syrup without the measuring cups.  Which of the following, if true, provides the strongest evidence that the company should not follow the consultant’s advice?A Studies have shown that customers who use cough syrup without a measuring cup frequently take either too little or too much of the medicine, rendering the dosage either ineffective or, in cases of overdose, dangerous.B The company has included a measuring cup with each bottle of cough syrup for the last 18 years.C Studies have shown that 85 percent of consumers possess at home either a measuring cup, a set of measuring spoons or both.D Many customers neglect to follow the recommended dosage of cough syrup even when the measuring cup is packaged along with the bottle of cough syrup.E Shipping the cough syrup bottles without the measuring cups will provide a marginal improvement in the number of cough syrup bottles that can be shipped is a standard package.
