.... a product line instead of single products, a more efficient development and maintainability process is anticipated [2] 27] Systematic methods with a focus on software product line engineering such as the Family Oriented Abstraction, Specification and Translation (FAST) process described in [31] begin to emerge. In [6] the co author of this paper describes a software product line as follows. A software product line typically consists of a product line architecture, a set of components and a set of products. Each product derives its architecture from the product line architecture, ....

....was done in the 90s, especially in the second half. Much of this work was related to organizational aspects, i.e. how to make developers in an organization efficiently develop software so that it can be used in several different products instead of just in a single one. Methods like ODM [19] FAST [22] or PuLSE mainly focus on this topic. The more technical aspects of the implementation of such systems are mostly left open in these approaches. Yet there are several techniques which cover these aspects. Examples are (static) meta programming [6] GenVoca [3] and many others. Common to all ....

....engine models first was incorporated through the mechanics and hardware. However, due to economies of scale that exist for these artefacts, car developers have moved the variation to the software. The second trend, i.e. delayed design decisions, can be illustrated through software product lines [Weiss Lai 1999][Jazayeri et al. 2000] Clements Northrop 2002] and the increasing configurability of software products. Over the last decade, many organizations have identified a conflict in their software development. On the one hand, the amount of software necessary for individual products is constantly ....

In the past few years, there have been a number of publications on how to design and implement software product lines such as, for instance, [Weiss Lai 1999][Jazayeri et al. 2000] Clements Northrop 2002] These and other publications such as [Bass et al. 1997] our co author s book [Bosch 2000] and conferences such as SPLC 1 [Donohoe 2000] and the upcoming SPLC 2 conference have increased interest in and use of software product lines.

....adhering assets in a product line. Perhaps it is not very surprising that in the early years of product line engineering a product line content knowledge base was not a metaphor. Today the situation is quite different; the sheer number of product line methods principles (for example [BFK 99] [WL99], KCH 90] in the last years makes accurate and advanced knowledge base techniques of major importance. One answer to this problem in the realm of transportation is GPS (Global positioning system) in the realm of product line engineering it is a product line content knowledge base. Up until ....

A minimal model contains the basic PLconcepts: products, assets, features and decisions (see section 4) This model is customizable, i.e. it can be used to derive a company or approach specific PLmodel like [WL99] or [BFK 99] Although minimal it is sufficient to build up a PL repository, which is independent from a given approach and can be used to derive a physical PL.

....benefits of product line engineering in general, and product line architectures in particular. However, they are often deterred from exploiting these ideas in practice due the lack of concrete, ready to use approaches for applying them. Well known methods for product line engineering, such as FAST [1], FODA [2] PuLSE [3] and Bosch [4] cover many of the central issues involved in supporting families of systems, but they all tend to address them at a high level of abstraction, and focus on the earlier phases of the life cycle. They also typically require some degree of tailoring before they ....

....FODAcom [8] applies feature modeling to the telecom domain. All these approaches lack a complete tool chain for the developers which allows to generate systems from a feature model. They use feature models mainly to organize the design and implementation work. The FAST method of Weiss and Lai [9] describes the process to develop and deploy customizable software families and requires the implementation of generators. However the modeling approach is not based on feature models. 5 Current State and Future Development The feature modeling and aspect oriented programming techniques ....

....exploiting the family members commonalities and controlling their variabilities. Such exploitation results in a software product line, which usually includes an infrastructure that enables rapid development of family members. A common problem of product line engineering as documented in [2] [10], is that the infrastructure can require a substantial initial investment. This investment is returned through the accumulated savings we obtain by deriving the family members from the common infrastructure. Figure 1 illustrates the underlying economic model: after a certain number of family ....

Weiss and Lai [14] present an approach that relates to the maturity level that we refer to a configurable product base. In their approach, a generator is developed that generates the specific product derivation that is required.

....The availability of configuration knowledge and the uniform representation of domain models, architectural knowledge and component properties thus allows to automate considerable parts of the component based development process. This approach may can be compared to domain specific languages [6][19] which offer a related way to generate applications. One advantage of out approach is the possibility to develop a software family evolutionary, starting with the common parts and step for step integrate additional components which implement variant parts of the domain. So the new knowledge can be ....

In response to this, the notion of software product lines, aiming at reuse between software products, but within an organization has achieved considerable amounts of attention during recent years, e.g. v.d.

Decision models for supporting the instantiation of domain models also appear in Lucent s product line approach [6]. KobrA s decision models have been influenced by this work, but extend it with support for higher level decisions, the capturing of relationships between decisions, and the description of variability in object oriented models. The most significant difference between KobrA s decision models and ....

By exploring what is common among the product line members, we avoid redeveloping common aspects of our software over and over again. By predicting how the product line members vary, we are able to design for the necessary changes [7] Introducing such a method into an industrial software ....
