People are indulging in an illusion whenever they find themselves explaining at a cocktail (鸡尾酒) party, say, that they are "in computers," or "in telecommunications," or "in electronic funds transfer". The implication is that they are part of the high-tech world. Just between US, they usually aren’t. The researchers who made fundamental breakthroughs in those areas are in a high-tech business. The rest of us are (71) of their work. We use computers and other new technology components to develop our products or to organize our affairs. Because we go about this work in teams and projects and other tightly knit working groups(紧密联系在一起的工作小组), we are mostly in the human communication business. Our successes stem from good human interactions by all participants in the effort, and our failures stem from poor human interactions.

The main reason we tend to focus on the (72) rather than the human side of the work is not because it’s more (73) , but because it’s easier to do. Getting the new disk drive installed is positively trivial compared to figuring out why Horace is in a blue funk (恐惧) or why Susan is dissatisfied with the company after only a few months. Human interactions are complicated and never very crisp (干脆的, 干净利落的) and clean in their effects, but they matter more than any other aspect of the work.

If you find yourself concentrating on the (74) rather than the (75) , you’re like the vaudeville character (杂耍人物) who loses his keys on a dark street and looks for them on the adjacent street because, as he explains, "The light is better there!".

西部服装公司专门生产牛仔服，其产品“狼”牌系列牛仔服结实耐磨，价格低廉，深受中低收入阶层青睐，在西川市的同类产品市场上长期稳居第一，近年来每年的销售增长率保持在5%左右。从去年起，美国一家著名牛仔服生产商在西川市的合资厂正式投产，其产品给西部服装公司在西川市的销售带来了巨大压力。今年上半年，“狼”牌系列的销售量比去年同期有较大幅度的下降，同时失去了市场霸主的地位。有鉴于此，西部服装公司决定进行战略调整，以挽回颓势，主要策略是开发新产品，由主管部门和财务部门抽调一些业务骨干，组成了一个专门机构负责这项工作。经过研究发现，西川市的服装消费需求出现了高档化和休闲化的趋势。西部服装公司决定，终止原有产品的生产，清理存货，集中力量开发出高档、休闲化的新款牛仔服。在销售方式上，公司改变了完全依赖中间商的做法，在西川市设立了多家专卖店，直接面向顾客。
