...rivation of individual products. Literature has already addressed how to create and instantiate generic product line assets, such as domain models and architectures to generate instance specific ones =-=[1, 2, 3]-=-, yet little attention has been given on how to actually deal with this genericity at the code level. This paper addresses the issue of handling product line variability at the code level. To this end...

Furthermore, due to the multitude of publications on...

Using PuLSE this knowledge is formalized but no tool support is given for automatically derive the needed artifacts for a selected feature (=-=Bayer et al. 2000-=-). Other configuration tools that specialize on software mass customization or family-based software development are GEARS developed by BigLever Software (www.biglever.com) and pure:variants provided ...

...g point for our implementation. Different modeling formalisms have been developed to capture the requirements as sketched in Sect. 2.1 in a structured manner. Best known are perhaps decision diagrams =-=[3]-=- and feature-based models [8, 1]. For our case study we use the feature modeling approach first introduced in Feature Oriented Domain Analysis (FODA) [8] and extended in subsequent work. A software fa...

...ible it is to integrate the two approaches. In conjunction with this workshop, one of the presented efforts was the iterative approach proposed by Carbon et al. [6]. This approach is based on PuLSE-I =-=[7]-=- which is a reuse-centric application engineering process. The proposed approach gives agile methods the role of tailoring a product for a specific customer during the application engineering process....

Halmans and Pohl [14] present work on how to communicate product line variability to customers. Ziadi et al.

Configuration and personalization for end-users. While product line approaches do typically not emphasize end-user customization this idea itself is not novel. Some software producers already go beyond providing basic installation wizards and provide more sophisticated support for end-users. For example, the enterprise business application SAP/R33 can be delivered with product configurators that allow us...
