Abstract [en]

This paper presents an exploratory study of an automotive manufacturer, which develops embedded software for over 150 products and has adopted a company-wide software product-line approach. The company is facing the introduction of a new software architecture in all products in near time. This architecture introduces new paradigms more explicitly, such as explicit software components and signal-based communication, newer technologies, and adheres to new standards. Concretely, the architecture consists of common infrastructure and other generic components. Such a fundamental and drastic technology change can be expected to have far-reaching consequences, both of technical and non-technical nature. In this study we systematically investigate the introduction of the new software architecture, by mapping individual elements of the architectural change to system properties and company functions. The study implies that the whole organization is affected, and the new architecture also influences the cooperation with suppliers.

Abstract [en]

The electronics in automotive systems give great possibilities. It has contributed to environmental improvements through reduced emissions and reduced fuel consumption, safety, driver assistance, and quality through better diagnostic capabilities.

Automotive systems are today distributed embedded systems that consist of several nodes that communicate with each other. The increasing possibilities have led to a situation where functions that used to be stand-alone, are today dependent on several inter-connected systems which all contribute to the desired functionality. This has increased the costs and the complexity to deal with the systems.

The automotive industry is adopting a new open software architecture, called AUTOSAR, that is intended to reduce the complexity. AUTOSAR also gives possibilities for coping with large product ranges and for component sharing. The introduction of AUTOSAR is an example of an architecture change without modifying the external functionality. We have chosen to call such changes system refactoring.

However, if the introduction of AUTOSAR is not successfully performed, there are risks for delayed development projects, which are costly for the automotive companies. Unfortunately, existing engineering standards and literature focus mostly on new product development and less on system re-factoring, and this gap needs to be filled. The goal of this research is to provide guidelines for refactoring, which provides support throughout the complete process of system architects in efforts to refactor the system.

This thesis identifies the characteristics of refactoring processes. This is done by empirical studies of the drivers behind refactoring, the effects we can expect from refactoring, and the process activities and characteristics. The result can be used to create guidelines for improving the work of refactoring.
