Interdependencies of product development decisions and the productionramp-up

摘要

Many companies, especially in high tech industries, are facing shrinking productlifecycles and increasingly complex production and product technologies. Selling of manygoods including semiconductors, disk-drives and telecommunications products has shrunk toa time span of less than a year. These market dynamics pressure production facilities to beginfull scale operations at a point when the underlying process technology is still poorlyunderstood. Consequently companies suffer from substantial yield losses which candramatically affect the economics of the product, the production facility, and business. Theproduction ramp-up will be defined as the time span equal to the difference between ‘time- tomarket’and’ time- to- volume’. A major goal of innovators is to reduce the ‘time –tomarket’,however they cannot evaluate the effects on the ‘time- to- volume’. This paper willgive insight into these interdependencies and compare two policies for the management of changes during production ramp-up.
