An extension to iStar framework as alternative to support design decisions in the task analysis performed in the Human Computer Interaction Area (HCI)

Abstract The goal of this work is to present i* framework as alternative to support design decisions in the Human Computer Interaction Area (HCI), mainly, in the process of task analysis. We show i* framework a modeling language suitable for an early phase of software system modeling to understand the problem domain, also, that provides methods to represent tasks, as well as support design decisions the development that satisfies the process requirements from the beginning until the end. To achieve our goal, approaches addressed to analyze notations aimed at task analysis and their representation. Finally, we present suggestions for improvement in the i* framework through a proposed extension for refining task model, instantiating examples and justifying our proposal through peer review.Abstract The goal of this work is to present i* framework as alternative to support design decisions in the Human Computer Interaction Area (HCI), mainly, in the process of task analysis.

DevOps model in practice: Applying a novel reference model to support and encourage the adoption of DevOps in a software development company as case study

DevOps has emerged as an approach to help organizations automate, cost optimization, increase profitability, improve the stability of the software development process and the responsiveness of organizations, and create a more agile development and release pipeline. However, its adoption, maintenance and evaluation continue to be a challenge for software organizations, due to the absence of solutions that formalize process elements in a detailed way, such as: practices, roles, artifacts, objectives, among others. This paper presents a DevOps Model, this model to support the adoption of DevOps, which provides a set of fundamental and complementary values, principles, dimensions, and practices. The practices suggest a set of items such as purpose, specific objectives and expected artifacts. The elements defined in proposed DevOps Model arise from the elements found in the studies analyzed through a systematic mapping study. Model evaluation was carried out through a software development company as case study. The results obtained have allowed the case study company to evaluate, diagnose and identify improvement opportunities to be carried out in the processes and projects where a DevOps-based approach is used, the above in a practical, useful, and adequate way that allows this type of companies and with a low use of resources, both economic investment and time. This is how the DevOps Model could guide professionals and organizations towards a better understanding of DevOps, in addition to minimizing the subjectivity and error of its interpretation, adoption and evaluation

Metrics Model to Complement the Evaluation of DevOps in Software Companies

This article presents a model to complement the evaluation of DevOps in software companies. It was designed by harmonizing the elements of the DevOps process identified through a systematic mapping of the literature and aimed to know the state of the art of methodological solutions and tools to evaluate DevOps in the industry. The process elements were identified, compared, and integrated into a common process structure that was used to establish a total of 11 metrics using the Goal-Question-Metric approach. The model was evaluated by a focus group of expert DevOps professionals. They determined that the model is clear, easy to apply, and provides valuable information to companies to improve their DevOps practices

“Radiografía” del estado de la reutilización de software en Colombia

Due to competitive markets, the software business wants faster, better, and cheaper solutions in a short amount of time. Software reuse emerges as a viable solution to these demands since it offers significant benefits, such as increased quality and efficiency and lower development costs and effort, as well as shorter commercialization times. This research aims to study and understand the state of the practice of software reuse in Colombia, to make comparisons with related works, and to offer an instrument for decision-making in companies that adopt these practices. To reach these objectives, three stages were proposed. In the first stage, the research questions were defined. In the second stage, a survey was developed, evaluated, and carried out to validate successful practices and adoption barriers in the context of the Colombian software industry. Finally, the results were analyzed and reported. This paper showed and evidenced the expectations, adoption barriers, and factors influencing the success of software reuse in Colombian industrial environments. In the same way, the experience from the development of this work serves as a roadmap for other regions that want to analyze the current state of reuse. Nevertheless, each organization needs to determine its capabilities and find the appropriate factors to be adopted to its context.Debido a los mercados competitivos, el negocio del software quiere soluciones más rápidas, mejores y más baratas en un período corto de tiempo.

En la segunda etapa se desarrolló, evaluó y realizó una encuesta para validar prácticas exitosas y barreras de adopción en el contexto de la industria de software colombiana. Finalmente, los resultados fueron analizados y reportados. El estudio mostró y evidenció las expectativas, barreras de adopción y factores que influyen en el éxito de la reutilización de software en entornos industriales en Colombia. El presente estudio muestra el estado actual de las prácticas de reutilización en la industria de software en Colombia. Asimismo, la experiencia en el desarrollo de este trabajo sirve como hoja de ruta para otras regiones que quieran analizar el estado actual de la reutilización. Sin embargo, cada organización necesita determinar sus capacidades y encontrar los factores adecuados para adaptarlos a su contexto

Toward a conceptual framework for designing sustainable cyber-physical system architectures: A systematic mapping study

Cyber-physical systems (CPS) represent devices whose components enable interaction between machines and processes. One of the biggest challenges of these systems today is the ability to adjust to changes at the time of execution as they are implemented in environments with a multidimensional complexity, this challenge is currently addressed from the design of the systems themselves by integrating sustainability. With this problem in mind, the present document describes a systematic mapping study of the literature with the goal of demonstrating the current panorama of the frameworks, designs, and/or models used at the time of initiating the development of a cyber-physical system. As a result, it has been concluded that there is a lack of guidelines to construct sustainable, and evolvable cyber-physical systems. To address these issues, a framework for designing sustainable CPS architectures is outlined

Semi-Automatic Mapping Technique Using Snowballing to Support Massive Literature Searches in Software Engineering

Systematic literature reviews represent an important methodology in Evidence-Based Software Engineering. To define the methodological route in these type of studies, in which a review of quantitative and qualitative aspects of primary studies is carried out to summarize the existing information regarding a particular topic, researchers use protocols that guide the construction of knowledge from research questions. This article presents a process that uses forward Snowballing, which identifies the articles cited in the paper under study and the number of citations as inclusion criteria to complement systematic literature reviews. A process that relies on software tools was designed to apply the Snowballing strategy and to identify the most cited works and those who cite them. To validate the process, a review identified in the literature was used. After comparing the results, new works that were not taken into account but made contributions to the subject of study emerged. The citation index represents the number of times a publication has been referenced in other documents and is used as a mechanism to analyze, measure, or quantitatively assess the impact of said publication on the scientific community. The present study showed how applying Snowballing along with other strategies enables the emergence of works that may be relevant for an investigation given the citations rate. That is, implementing this proposal will allow updating or expanding systematic literature studies through the new works evidenced
