每个产品都有几个关键因素,使产品具竞争性。成功的产品对这些因素有十分清楚的定义,而且所有的设计、生产和市场行为都紧紧围绕著这个中心展开。对于航空电子产品,可能是性能和重量;对于工业控制,可能是可靠性和应付恶劣环境的能力;而在电信上,更注重的是面市时间和短的产品生命期。 Each product has several key factors that make the product competitive. Successful products have a very clear definition of these factors, and all design, production, and marketing activities are closely centered around this center. For avionics, it may be performance and weight; for industrial control, it may be reliability and ability to cope with harsh environments; and in telecommunications, more emphasis is on time-to-market and short product life.
