How the managers lead decides a company's fate. It is over sixty years since the first gear jobber built in Taiwan. Today, some of the gear jobbers are big and strong. They followed the world trend and accumulated valuable know-how and manage experience. Why are they big and strong? We picked up three gear jobbers. We interviewed with their top managers to find out the key success factors of gearing industry. We hope it is useful for the gear jobbers in Taiwan.

一个公司的兴衰，自然要看公司管理阶层如何带领公司往能生存方向前进，齿轮加工业在台湾已经超过60年的历史，其中许多厂商也顺应世界的趋势累积了宝贵的技术能力与经营经验，我们要探讨台湾几家规模较大的齿轮加工厂如何能在过去几年中成长与茁壮，我们将透过访谈来找出齿轮加工业中的关键成功因素。
