  • Combining Agile Development and Software Product Lines in Automotive: Challenges and Recommendations
    2018 IEEE International Conference on Engineering Technology and Innovation (ICE ITMC), 2018
    Co-Authors: Philipp Hohl, Michael Stupperich, Jürgen Münch, Kurt Schneider
    Abstract:

    Software product lines (SPLs) are used throughout the Automotive industry. SPLs help to manage the large number of variants and to improve quality by reuse. In order to develop high quality software faster, agile software development (ASD) practices are introduced. From both the research and the management point of view it is still not clear how these two approaches can be combined. We derive recommendations to combine ASD and SPLs based on challenges identified for an Automotive-specific model. This study combines the outcome of a literature review and a qualitative interview study with 16 practitioners from the Automotive Domain. We evaluate the results and analyze the relationship between ASD and SPLs in the Automotive Domain. Furthermore, we derive recommendations to combine ASD and SPLs based on challenges identified in the Automotive Domain. This study identifies 86 individual challenges. Important challenges address supplier collaboration and faster software release cycles without loss of quality. The identified challenges and the derived recommendations show that the combination of ASD and SPL in the Automotive industry is promising but not trivial. There is a need for an Automotive-specific approach that combines ASD and SPL.

  • PROFES - Real-Life Challenges on Agile Software Product Lines in Automotive
    Product-Focused Software Process Improvement, 2017
    Co-Authors: Philipp Hohl, Kurt Schneider, Jürgen Münch, Michael Stupperich
    Abstract:

    Context: The current situation and future scenarios of the Automotive Domain require a new strategy to develop high quality software in a fast pace. In the Automotive Domain, it is assumed that a combination of agile development practices and software product lines is beneficial, in order to be capable to handle high frequency of improvements. This assumption is based on the understanding that agile methods introduce more flexibility in short development intervals. Software product lines help to manage the high amount of variants and to improve quality by reuse of software for long term development.

  • ICSSP - Searching for common ground: existing literature on Automotive agile software product lines
    Proceedings of the 2017 International Conference on Software and System Process - ICSSP 2017, 2017
    Co-Authors: Philipp Hohl, Michael Stupperich, Jürgen Münch, Javad Ghofrani, Kurt Schneider
    Abstract:

    The digital transformation of the Automotive industry has a significant impact on how development processes need to be organized in future. Dynamic market and technological environments require capabilities to react on changes and to learn fast. Agile methods are a promising approach to address these needs but they are not tailored to the specific characteristics of the Automotive Domain like product line development. Although, there have been efforts to apply agile methods in the Automotive Domain for many years, significant and widespread adoptions have not yet taken place. The goal of this literature review is to gain an overview and a better understanding of agile methods for embedded software development in the Automotive Domain, especially with respect to product line development. A mapping study was conducted to analyze the relation between agile software development, embedded software development in the Automotive Domain and software product line development. Three research questions were defined and 68 papers were evaluated. The study shows that agile and product line development approaches tailored for the Automotive Domain are not yet fully explored in the literature. Especially, literature on the combination of agile and product line development is rare. Most of the examined combinations are customizations of generic approaches or approaches stemming from other Domains. Although, only few approaches for combining agile and software product line development in the Automotive Domain were found, these findings were valuable for identifying research gaps and provide insights into how existing approaches can be combined, extended and tailored to suit the characteristics of the Automotive Domain.

  • HICSS - Evaluation of Variability Concepts for Simulink in the Automotive Domain
    2015 48th Hawaii International Conference on System Sciences, 2015
    Co-Authors: Carsten Kolassa, Holger Rendel, Bernhard Rumpe
    Abstract:

    Modeling variability in Matlab/Simulink becomes more and more important. We took the two variability modeling concepts already included in Matlab/Simulink and our own one and evaluated them to find out which one is suited best for modeling variability in the Automotive Domain. We conducted a controlled experiment with developers at Volkswagen AG to decide which concept is preferred by developers and if their preference aligns with measurable performance factors. We found out that all existing concepts are viable approaches and that the delta approach is both the preferred concept as well as the objectively most efficient one, which makes ?Simulink a good solution to model variability in the Automotive Domain.

  • software traceability in the Automotive Domain challenges and solutions
    Journal of Systems and Software, 2018
    Co-Authors: Salome Maro, Janphilipp Steghofer, Miroslaw Staron
    Abstract:

    Abstract In the Automotive Domain, the development of all safety-critical systems has to comply with safety standards such as ISO 26262. These standards require established traceability, the ability to relate artifacts created during development of a system, to ensure resulting systems are well-tested and therefore safe. This paper contrasts general traceability challenges and solutions with those specific to the Automotive Domain, and investigates how they manifest in practice. We combine three data sources: a tertiary literature review to identify general challenges and solutions; a case study with an Automotive supplier as validation for how the challenges and solutions are experienced in practice; and a multi-vocal literature review to identify challenges and solutions specific to the Automotive Domain. We found 22 challenges and 16 unique solutions in the reviews. 17 challenges were identified in the case study; six remain unsolved. We discuss challenges and solutions from the perspectives of academia, tool vendors, consultants and users, and identify differences between scientific and “grey” literature. We discuss why challenges remain unsolved and propose solutions. Our findings indicate that there is a significant overlap between general traceability challenges and those in the Automotive Domain but that they are experienced differently.

  • 2nd International Workshop on Automotive Systems and Software Architectures (WASA)—Introduction to special section
    Journal of Systems Architecture, 2017
    Co-Authors: Yanja Dajsuren, Harald Altinger, Miroslaw Staron
    Abstract:

    Automotive software engineering was officially introduced more than a decade ago into the software community addressing research challenges and technical issues encountering software development in the Automotive Domain. A modern-day premium class vehicle contains up to 100 000 000 lines of executable code running on multiple microcontrollers creating a heterogeneous, deeply coupled networking system. Nowadays trends like car2x, (fully) electric vehicles or self-driving cars are all based on software. Those new features will require new engineering approaches and more advanced software architectures suitable for Automotive Domain.

  • challenges of establishing traceability in the Automotive Domain
    International Conference on Software Quality, 2017
    Co-Authors: Salome Maro, Miroslaw Staron, Janphilipp Steghofer
    Abstract:

    Traceability, i.e., relationships between artifacts in software development, is prescribed by quality standards such as ISO 26262 and therefore mandatory for Automotive companies that develop safety-critical systems. However, establishing traceability is a challenge for many Automotive companies. The objective of this study is to identify traceability challenges and solutions in this Domain and compare these challenges and solutions with the ones in literature. To achieve this, we conducted a case study with a large Automotive supplier to discover their traceability challenges and a tertiary literature review on existing traceability literature surveys to identify reported challenges and their solutions. We found 13 challenges from the literature study, of which ten were also found at the company. Three challenges are solved at the company with solutions that correlate with those proposed in literature, three are partially solved while four are still unsolved even though there are solutions in literature.

  • defect prediction over software life cycle in Automotive Domain state of the art and road map for future
    International Conference on Software Engineering, 2014
    Co-Authors: Rakesh Rana, Miroslaw Staron, Jorgen Hansson, Martin Nilsson
    Abstract:

    Software today provides an important and vital role in providing the functionality and user experience in Automotive Domain. With ever increasing size and complexity of software together with high demands on quality and dependability, managing software development process effectively is an important challenge. Methods of software defect predictions provide useful information for optimal resource allocation and release planning; they also help track and model software and system reliability. In this paper we present an overview of defect prediction methods and their applicability in different software lifecycle phases in the Automotive Domain. Based on the overview and current trends we identify that close monitoring of in-service performance of software based systems will provide useful feedback to software development teams and allow them to develop more robust and user friendly systems.

  • Combining Agile Development and Software Product Lines in Automotive: Challenges and Recommendations
    2018 IEEE International Conference on Engineering Technology and Innovation (ICE ITMC), 2018
    Co-Authors: Philipp Hohl, Michael Stupperich, Jürgen Münch, Kurt Schneider
    Abstract:

    Software product lines (SPLs) are used throughout the Automotive industry. SPLs help to manage the large number of variants and to improve quality by reuse. In order to develop high quality software faster, agile software development (ASD) practices are introduced. From both the research and the management point of view it is still not clear how these two approaches can be combined. We derive recommendations to combine ASD and SPLs based on challenges identified for an Automotive-specific model. This study combines the outcome of a literature review and a qualitative interview study with 16 practitioners from the Automotive Domain. We evaluate the results and analyze the relationship between ASD and SPLs in the Automotive Domain. Furthermore, we derive recommendations to combine ASD and SPLs based on challenges identified in the Automotive Domain. This study identifies 86 individual challenges. Important challenges address supplier collaboration and faster software release cycles without loss of quality. The identified challenges and the derived recommendations show that the combination of ASD and SPL in the Automotive industry is promising but not trivial. There is a need for an Automotive-specific approach that combines ASD and SPL.
