    Maintainability is a Versatile Quality Attribute
    (Softwaretechnik-Trends Band 36, Heft 3, 2016) Knodel, Jens; Naab, Matthias
    Software architecture evaluation has been widely accepted as a powerful means to mitigate risks in the design and evolution of software systems. To date we have conducted more than 75 architecture evaluation projects with industrial customers in the past decade. One recurring lesson learned that we experienced across many architecture evaluation projects is that maintainability indeed is a versatile quality attribute and its evaluation requires a mix of quantitative and qualitative checks.

    Mitigating the Risk of Software Change in Practice Retrospective on More Than 50 Architecture Evaluations in Industry (Keynote Paper)
    (Softwaretechnik-Trends Band 34, Heft 2, 2014) Knodel, Jens; Naab, Matthias
    Architecture evaluation has become a mature instrument to make decisions about software systems, assess and mitigate risks, and to identify ways for improvement and migration of software systems. While scientific literature on approaches is available, publications on practical experiences are rather limited. In this paper, we share our experiences - after having performed more than 50 architecture evaluations for industrial customers in the last decade. We compiled facts and consolidate our findings about architecture evaluations in industry and especially highlight the role of reverse engineering in these projects. We share our lessons learned and provide data on common believes and provide examples for common misconceptions on the power of reverse engineering. This industrial and practical perspective allows practitioners to benefit from our experience in their daily architecture work and how to guide research of the scientific community.

    Static architecture evaluation of open source reuse candidates
    (NODe 2006 – GSEM 2006, 2006) Knodel, Jens; Muthig, Dirk; Naab, Matthias
    Open source software systems provide a variety of field-tested components offering software development organizations the potential to reuse and adapt such components for their own purposes. The main challenge before achieving the reuse benefits is to acquire a thorough understanding of open source software systems (i.e., the reuse candidates) in order to reason about alternative solutions, to learn about the points where to adapt the system and eventually to decide whether or not to invest into reuse. Manually analyzing even small systems is a time-consuming, complex and costly task. In this paper we present a case study where we analyzed the Apache Tomcat web server supported by a software architecture visualization and evaluation tool and demonstrate how the tool facilitated our comprehension tasks to learn about the architectural means and concepts.

    A Systematic Approach for Comparing and Reusing Design Alternatives
    (Softwaretechnik-Trends Band 25, Heft 2, 2005) Knodel, Jens; Forster, Thomas; Girard, Jean-François
    This work introduces an approach to mine field-tested design solutions when defining the architecture of a new product line. The design comparison approach (DCA) compares design solution alternatives implemented in existing systems and evaluates their advantages and drawbacks. This explicit comparison and analysis enables the development of high quality product line architectures by incorporating field-tested, proven concepts and strategies. The experiences gained so far in case studies support the claim that the resulting architecture profits from the application of the DCA approach.
