Danfoss Drives - one of the largest producers of frequency converters in the world - has been doing Software Product Line development for its frequency converter products for about 3 years. This paper describes the approach used and the experiences with it. It discusses processes, ways to convince the unconvinced and arising tool issues when doing product line development. This paper is a follow-up on a previous article which described the product line migration process in detail.
