马丁吉他公司成立于1833年,位于宾夕法尼亚州拿撒勒市被公认为世界上最好的乐器制造商之一,就像Steinway的大钢琴、RollsRoyce的轿车,或者Buffet的单簧管一样,马丁吉他每把价格超过10000美元,却是你能买到的最好的东西之一。这家家族式的企业历经艰难岁月,已经延续了六代。目前的首席执行官是克里斯琴·弗雷德里克·马丁四世,他秉承了吉他的制作手艺。他甚至遍访公司在全世界的经销商,为它们举办培训讲座。很少有哪家公司像马丁吉他一样有这么持久的声誉,那么,公司成功的关键是什么?一个重要原因是公司的管理和杰出的领导技能,它使组织成员始终关注像质量这样的重要问题。马丁吉他公司自创办起做任何事都非常重视质量。即使近年来在产品设计、分销系统以及制造方法方面发生了很大变化,但公司始终坚持对质量的承诺。公司在坚守优质音乐标准和满足特定顾客需求方面的坚定性渗透到公司从上到下的每一个角落。不仅如此,公司在质量管理中长期坚持生态保护政策。因为制作吉他需要用到天然木材,公司非常审慎和负责地使用这些传统的天然材料,并鼓励引入可再生的替代木材品种。基于对顾客的研究,马丁公司向市场推出了采用表面有缺陷的天然木材制作的高档吉他,然而,这在其他厂家看来几乎是无法接受的。马丁公司使新老传统有机地整合在一起。虽然设备和工具逐年更新,雇员始终坚守着高标准的优质音乐原则。所制作的吉他要符合这些严格的标准,要求雇员极为专注和耐心。家庭成员弗兰克·亨利·马丁在1904年出版的公司产品目录的前言里向潜在的顾客解释道:“怎么制作具有如此绝妙声音的吉他并不是一个秘密。它需要细心和耐心。细心是指要仔细选择材料,巧妙安排各种部件。关注每一个使演奏者感到惬意的细节。所谓耐心是指做任何一件事不要怕花时间。优质的吉他是不能用劣质产品的价格造出来的。但是谁会因为买了一把价格不菲的优质吉他而后悔呢?”虽然100年过去了,但这些话仍然是公司理念的表述。虽然公司深深地植根于过去的优良传统,现任首席执行官马丁却毫不迟疑地推动公司朝向新的方向。例如,在20世纪90年代末,他作出了一个大胆的决策,开始在低端市场上销售每件价格低于800美元的吉他。低端市场在整个吉他产业的销售额中占65%。公司DXM型吉他是1998年引入市场的,虽然这款产品无论外观、品位和感觉都不及公司的高档产品,但顾客认为它比其他同类价格的绝大多数吉他产品的音色都要好。马丁为他的决策解释道:“如果马丁公司只是崇拜它的过去而不尝试任何新事物的话,那恐怕就不会有值得崇拜的马丁公司了。”马丁公司现任首席执行官马丁的管理表现出色,销售收入持续增长,在2000年接近6亿美元。位于拿撤勒市的制造设施得到扩展,新的吉他品种不断推出。雇员们描述他的管理风格是友好的、事必躬亲的,但又是严格的和直截了当的。虽然马丁吉他公司不断将其触角伸向新的方向,但却从未放松过对尽其所能制作顶尖产品的承诺。在马丁的管理下,这种承诺决不会动摇。通过雇员们的描述他的管理风格他是怎样的领导方式()。

Literacy Volunteer Last summer I went through a training program and became a literacy volunteer (扫盲志愿者). The training I received, though excellent, did not tell me how it was to work with a real student, however. When I began to discover what other people's lives were like because they could not read, I realized the true importance of reading. My first student Jane was a 44-year-old single mother of three. In the first lesson, I found out she walked two miles to the nearest supermarket twice a week because she didn't know which bus to take. When I told her I would get her a bus schedule, she told me it would not help because she could not read it. She said she also had difficulty once she got to the supermarket because she couldn't always remember what she needed. Since she did not know words, she could not write out a shopping list. Also, she could only recognize items by their labels. As a result, if the product had a different label, she would not recognize it as the product she wanted. As we worked together, learning how to read built Jane's self-confidence, which encouraged her to continue in her studies. She began to make rapid progress and was even able to take the bus to the supermarket. After this successful trip, she reported how self-confident she felt. At the end of the program, she began helping her youngest son, Tony, a shy first grader, with his reading. She sat with him before he went to sleep and together they would read bedtime stories. When his eyes became wide with excitement as she read pride was written all over her face, and she began to see how her own hard work in learning to read paid off. As she described this experience, I was proud of myself, too. I found that helping Jane to build her self-confidence was more rewarding than anything I had ever done before. As a literacy volunteer, I learned a great deal about teaching and helping others. In fact, I may have learned more from the experience than Jane did. She could write out a shopping list.()
