Fifh International Workshop on Experiences and Empirical Studies on Sofware Reuse (WEESR 2022) Jaime Chavarriaga Universidad de los Andes Colombia ja.chavarriaga908@uniandes.edu.co Luisa Rincón Pontifcia Universidad Javeriana Cali Colombia lfrincon@javerianacali.edu.co Angela Villota Universidad ICESI Colombia apvillota@icesi.edu.co ABSTRACT In the Workshop on Experiences and Empirical Studies on Software Reuse (WEESR) researchers and practitioners discusses in-progress research regarding experiences and empirical studies applying reuse techniques in non-academic environments. The ffth edition of this workshop, the WEESR 2022, was co-located with the 26th Interna- tional Systems and Software Product Line Conference (SPLC’22). There, attendees discussed two original papers presenting empiri- cal studies related to reuse in the software industry, one using an interview-based methodology and the other using a survey-based methodology.

Many companies rely on technologies such as components, object orientation, and product lines to promote reuse and achieve these benefts. However, diferent studies shown that non-technical factors, such as organization, processes, and human involvement, appeared to be at least as important than the technologies [1][2][3]. The Fifth Workshop on Experiences and Em- pirical Studies on Software Reuse (WEESR 2022) aimed at discussing how technical and non-technical factors may afect in-practice exit- ing proposals to achieve systematic reuse in software organizations.

Javad Ghofrani, Paria Heravi, Kambiz Aghababazade and Mohammad Divband, presented initial results from an interview-based study with 16 software developers to get an understanding of trust issues and limitations when it comes to reusing open-source software. In particular, this paper analyzes how the knowledge about dependency security vulnerabilities is often missed by developers and thus, afects the product being de- veloped. This kind of problem is also noticeable in software product lines. Considering the responses, the authors identifed fve prelimi- nary problems and perspectives to address them. The preliminary results also provide insights for elaborating a more wide-ranging study in the future. Design for the analysis of variability management in the indus- try. Ana Eva Chacón-Luna, Antonio Manuel Gutierrez, David Bena- vides and Lidia Fuentes, presented a design for a survey to collect information about the practices for managing commonalities and variabilities in companies with a product portfolio. The authors have hypothesized that companies building a port- folio (a set) of similar products will use techniques for managing variability. However, many of these companies will probably be unaware of the existing techniques and will use diferent names or adapted techniques instead of those proposed by the SPLE litera- ture. This paper includes details regarding how the authors designed the survey and how they plan to collect the data, conduct the study and analyze the results. Also, the paper presents some strategies to reduce the threats to validity identifed by the authors. REFERENCES [1] Cagatay Catal. 2009. Barriers to the adoption of software product line engineering.
