https://submissions.jot.fm/index.php/jot/issue/feed Journal of Object Technology 2021-01-28T09:01:54+00:00 Journal of Object Technology noreply@jot.fm Open Journal Systems <p>JOT, the Journal of Object Technology, is a peer-reviewed, free and open-access journal dedicated to the timely publication of previously unpublished research articles, surveys, tutorials, and technical notes on all aspects of software and language engineering, with a particular but not exclusive focus on object technology.</p> <p>JOT publishes original, timely, high-quality articles that address important research and application topics; the results described must be reproducible, extensible and scalable. Claims must be validated through, for example, empirical studies, simulation or proofs.</p> <p>Submitted works will be assessed on originality, significance, technical soundness and quality of presentation. Contributions should conform to generally accepted practices for scientific papers with respect to organization, clarity, and style. Papers about industrial practices, education experiences, as well as state-of-the-art surveys, are welcome.</p> <p>Besides technical contributions, JOT solicits papers about software tools and environments.</p> https://submissions.jot.fm/index.php/jot/article/view/441 The Evolution of Software Design Practices Over a Decade: A Long Term Study of Practitioners 2021-01-28T09:01:54+00:00 Omar Badreddin obbadreddin@utep.edu Khandoker Rahad karahad@miners.utep.edu Andrew Forward aforward@uottawa.ca Timothy Lethbridge timothy.lethbridge@uottawa.ca <p>We present the results of a survey of 248 software practitioners conducted in three phases ten years apart. The goal of the study is to uncover trends in the practice of software design and the adoption patterns of modeling languages such as UML. The first phase was conducted in April-December 2007 and included 113 responses. The second phase was conducted in March-November 2017 and included 115 responses. The third phase is a post-survey study was conducted in November 2018 and included additional questionnaires with 20 participants. All survey phases were conducted online, employed identical solicitation mechanisms, and included the same set of questions. The survey results are analyzed within each phase and across phases. We present the results and analysis of the data identifying upward and downward trends in design and modeling practices.</p> <p>The results indicate a significant increase in the use of well-defined and formal modeling languages, as well as a marked increase in the adoption of Domain-Specific Languages. This is also reflected in a significant increase in the adoption of forward engineering methodologies. A key motivation for this uptake is a concern that programming languages and platforms may become quickly outdated. Unfortunately, there has been a consistent dissatisfaction with modeling tools features, particularly their ability to support effective communication and collaboration. This is mirrored by increasing dissatisfaction with modeling tools usability and learnability.</p> <p>Future projections of this study suggest that diversity in modeling languages and tools is likely to continue to grow, as well as the increase in reliance on models for automated artifacts generation. As such, model and tool interoperability is likely to become an even greater concern for the years to come. The results of this study can help researchers, practitioners, and educators to focus efforts on issues of relevance and significance to the profession. Specifically, this research will advocate to build better software modeling tools and promote modeling to the educators.</p> 2021-01-28T08:37:21+00:00 Copyright (c) 2021 Omar Badreddin, Khandoker Rahad, Andrew Forward, Timothy Lethbridge
