software development methods have been evolved to enable producing usable systems rapidly while considering all requirements. Several studies have focused on the need to balance between rapid development and capturing requirements related to user experience and business workflow. This balance has become more urging during COVID19 because many businesses want to quickly transfer to usable electronic systems that are accurate, efficient, easy to learn, satisfy users and support remote work. Therefore, this paper proposes a framework by integrating Rapid Application development (RAD) method with Participatory Design (PD) method for enabling rapid production of usable systems. Both RAD and PD consist of design stages that can overlap and generate new phases where users participate in the design process and accelerate the production. Five usability tests are also added to the framework to validate the usability of the design at all stages. The Action Research method is used to assess the framework empirically in a context of an urgent need to an electronic system, and qualitative data analyses were conducted. The results show that the framework can be adopted by software companies because it satisfies the requirements of adopting software development methods. Also, the system developed using the framework is usable. The paper concludes that COVID19 affects software development by emphasizing rapid development while maintaining workflow. Also, using video conference for remote design assists in meeting users more frequently and in creating concise requirement documentation.

Autonomic Coordination of Skeleton-Based Applications Over CPU/GPU Multi-Core Architectures

INTERNATIONAL JOURNAL OF PARALLEL PROGRAMMING 2017年第2期45卷 203-224页

作者： Goli, Mehdi Gonzalez-Velez, Horacio Robert Gordon Univ Aberdeen Scotland Natl Coll Ireland Dublin Ireland

Widely adumbrated as patterns of parallel computation and communication, algorithmic skeletons introduce a viable solution for efficiently programming modern heterogeneous multi-core architectures equipped not only with traditional multi-core CPUs, but also with one or more programmable Graphics Processing Units (GPUs). By systematically applying algorithmic skeletons to address complex programming tasks, it is arguably possible to separate the coordination from the computation in a parallel program, and therefore subdivide a complex program into building blocks (modules, skids, or components) that can be independently created and then used in different systems to drive multiple functionalities. By exploiting such systematic division, it is feasible to automate coordination by addressing extra-functional and non-functional features such as application performance, portability, and resource utilisation from the component level in heterogeneous multi-core architectures. In this paper, we introduce a novel approach to exploit the inherent features of skeleton-based applications in order to automatically coordinate them over heterogeneous (CPU/GPU) multi-core architectures and improve their performance. Our systematic evaluation demonstrates up to one order of magnitude speed-up on heterogeneous multi-core architectures.

COMPUTING IN SCIENCE & ENGINEERING 2018年第6期20卷 81-94页

作者： Maciol, Piotr Michalik, Kazimierz AGH Univ Sci & Technol Krakow Poland

Numerical modeling is a tool commonly used by both researchers and engineers. For several reasons, the quality of scientific codes frequently deprecates. One of the possible remedies is the application of advanced programming and software development methods. In this paper, we introduce the application of metaprogramming and generic programming in C++ to control the correctness of multiscale models. Additionally, it is shown how both methods increase reusability and quality of the code. A short introduction to metaprogramming and generic programming is included, as well as the proof of the concept. Exemplary codes are also included and discussed.

Interacting with Classic Design Engineering

INTERACTING WITH COMPUTERS 2015年第4期27卷 440-457页

Triggered by our occasionally tense field experiences relating to the implementation and institutionalization of usability in design engineering organizations that are characterized by traditional engineering education and thinking, we have earlier suspected that the activities associated with human-centered design were orthogonal to the design engineering practices otherwise in place. While noting that other human factors professionals have had comparable challenges relating to multidisciplinary design, we have, however, reached a point where we rather are suggesting that the ontological, epistemological and methodological grounding of classic design engineering, under some circumstances, could be the direct cause for friction between that discipline and that of human factors. In a way taking our own medicine, we have thus arrived at a place where we are realizing the need for an ethnographical exploration and improved understanding of classic design engineering fundamentals, appreciating that a more successful and fruitful interaction and cooperation with that essential discipline very well could spring from a deeper and more nuanced understanding of the mindset of the classic design engineer. The main part of the present paper pivots around developing such an insight, hoping to contribute to the effective, efficient and satisfactory outcome of multidisciplinary cooperation for those who find themselves being tasked with human-centric work in traditional engineering organizations.

software start-ups are aiming to develop cutting-edge software products under highly uncertain conditions, overcoming fast-growing markets under multiple influences. This study aims to identify and analyse the existing scientific literature regarding software development methodologies and practices in software start-ups published between January 2006 and December 2017 using the systematic mapping study. The results identified 37 relevant primary studies out of 1982 papers. To validate the results from the mapping study, an empirical study was based on the research data collected from 14 real-life software start-ups located in Finland, Italy and Norway. The result shows that Agile and Lean start-up methodologies are the most commonly used in software start-ups due to the flexible nature and easy tailoring. A total of 144 software development work practices are extracted from the primary studies. This study contributes to the research in several ways: (i) provides state of the art regarding software development methods and practices in software start-up contexts, (ii) reports commonly used methods along with its benefits identified in primary studies and (iii) identifies opportunities for future software start-up research.

JOURNAL OF INFORMATION TECHNOLOGY RESEARCH 2011年第3期4卷 50-63页

作者： Ghinea, Gheorghita Bygstad, Bendik Satpathy, Manoranjan Brunel Univ Sch Informat Syst Comp & Math Uxbridge Middx England Norwegian Sch Informat Technol Oslo Norway Abo Akad Univ Turku Finland

In this paper, the authors investigate the professional practices of software developers from two different cultures-Norway and India. The authors examine if systematic differences exist between Norwegian and Indian software developers in their professional practice. Using Hofstede's cultural dimensions, the authors expected to find cultural differences between the two groups of professionals. Building on a survey among software developers in the two countries, the authors have the following conclusions. Firstly, the main finding is that there are surprisingly few differences between the two groups, giving support to the view of a common professional culture. Secondly, the few differences that are observed cannot easily be explained by Hofstede's cultural dimensions.

"Technical excellence" is a nebulous term in agile software development. This vagueness is risky, as it creates a gap in the understanding of agile that may have consequences on how software development practitioners operate. Technical excellence is the only reference to quality in the agile manifesto. Hence, it is fundamental to understand how agile software development practitioners both interpret and implement it. We conducted interviews with twenty agile practitioners about their understanding of the term "technical excellence" and how they approach the task of fostering it. To validate the findings, two focus group meetings were conducted after the interviews and the analysis of the data were completed. We found that the configuration of technical excellence is made of four traits: (1) software craftsmanship;(2) software quality (3) mindset for excellence;and (4) consistency with good software engineering practices. Fostering technical excellence is a continuous endeavor. Further, we identified three key principles that were commonly cited as essential to implementing technical excellence, namely: 1) continuous learning;2) continuous improvement;and 3) control of excellence. Based on our findings, we present several recommendations for software development teams seeking to better realize the goal of technical excellence in their agile implementation.

At Carnegie Mellon University in Silicon Valley, the graduate master program ends with a practicum project during which students serve as software engineering consultants for an industry client. In this context, students are challenged to demonstrate their ability to work on self-managing and self-organizing teams. This paper presents a field study of the software Engineering Method and Theory (SEMAT) Essence framework. The objective is to evaluate the effectiveness of the Essence's novel state-based monitoring and goal-driven steering approach provided by the Essence kernel alphas and their states. The researchers conducted the study on seven graduate master student teams applying the approach throughout their practicum projects. The research methodology involves weekly observation and recording of each team's state progression and collecting students' reflection on the application of the approach. The main result validates that the approach provides student teams with a holistic, lightweight, non-prescriptive and method-agnostic way to monitor progress and steer projects, as well as an effective structure for team reflection and risk management. The paper also validates that the Essence kernel provides an effective mechanism for monitoring and steering work common to most student software projects. This includes the work done during project initiation as well as the work done at the project or release level. Support for technical work should come from additional practices added on top of the kernel, or by extending or altering the kernel definition. The conclusion is that the approach enables students to learn to steer projects effectively by addressing the various dimensions of software engineering. Hence the approach could be leveraged in software engineering education.
