第33题: [多项选择]
Is time management important or not Why
参考答案:Suggested answers:
a.Time management is particularly necessary for the owner/manager of a small firm, because the enterprise is to achieve its objectives. They need to manage efficiently the limited time he or she can devote to the affairs of the business. They need to fulfill expected community obligations. They need to keep up with rapid environmental changes and advancements in management science, and they need to plan for succession in management and continuity of business operations.
b.Time management is necessary for employees as well. Employees must manage their own times, though they usually have their time managed for them by company regulations. With so many essential duties to perform, and only the same amount of time available as is used by each of a number of persons in big business, the finite number of hours in a day is usually the most serious problem of the typical employee. They have to learn to get their priorities right, or they are most likely to get into a panic and fail to meet the deadline.
c.With all of its advantages, even being one’s own boss has a maximum price in terms of time that can be devoted to the business and still leave enough for the enterpriser to enjoy a normal outside life. A major goal of time management is to keep this price for success reasonable. “One realizes the full importance of time only when there is little of it left. Every man’s greatest capital asset is his unexpired years of productive life. ”(P. W. Litchfield)
d.Time management is crucial in doing business. To manage his or her time more effectively, the entrepreneur should (A) rank the various jobs in order of importance; (B) divide them into at least two classes based on the manager’s ability to control the time when they will be performed; (C) decide which ones can best be delegated to other members of the organization; (D) determine those where time can be saved in the long run by adopting suitable procedures; (E) select or formulate suitable aids to time economy. These five steps in time management have been listed in their order of importance and can be discussed in that sequence.
e.Time management is crucial to business success. The manager must first define his or her goals and set priorities. Time is limited, fixed within absolute and reasonable limits. Choice is essential, and ranking is the only intelligent approach. “First things first” should be the guide, but like other maxims it is often difficult to accomplish, mainly because of lack of planning. Which should come first, serving a customer when all other employees are busy or doing essential paperwork that must be completed before tomorrow The customer’s arrival could not have been predicted a few minutes earlier, but essential paperwork was known days or even months in advance. You must be the judge—it’s your enterprise.
f.Ranking involves valuation. First to be accomplished are those mandatory duties required by law. “You will never‘find’time for anything. If you want time, you must make it. ”(—Charles Bixton) Time management involves self-discipline. We all sometimes dissipate time on such things as idle conversation, newspaper reading, or just daydreaming. Entrepreneurs must keep up with important new events that might affect their business or family life, but many spend more time than necessary in the process. Conversation also is needed to spark fresh ideas, to make new friends, and to build goodwill, but a lot of time is often wasted on unimportant exchanges of comments regarding the weather, the latest gossip, and the like. Experience shows that from one to two hours per day can often be saved from these sources alone. Of course, time-consuming habits such as these are often relaxing and enjoyable. The main point is that unless controlled they frequently use up the only time the entrepreneur has to use for deliberation and planning.
g.Time management considerations are some of the most important factors that sales management should be concerned with. It is important for sales management to convey to members of the sales force the value of their time. Sales managers need to do everything possible to insure that this unproductive time is held to a minimum and that territory coverage is possible in an efficient way.
h.An important ability of successful sales representatives is to know how to use their time efficiently, plan their routes, service accounts, and develop prospective accounts. Salesmanship is very important. Yet of the three things that make for sales productivity-effective two- way communication skills, knowledge of customers and products, and prudent investment of available sales time-the way a salesman invests his time may well be the most critical. Time equals money.
答案解析:[解析] time management善用时间技巧。salesmanship推销术,销售技巧。dissipate (time) 驱散,浪费,挥霍(时间)。 prudent investment审慎投
