Item Técnicas de comitês para a estimação de esforço na correção de software(2019-12-10) Guimarães, Ariana Lima; Soares, Rodrigo Gabriel Ferreira; http://lattes.cnpq.br/2526739219416964; http://lattes.cnpq.br/2605671850587343A well-defined planning of a software project, since the early stages, is indispensable to its success, whether the development refers to product’s creation or maintenance. Accordingly to the software life cycle, maintenance is continuously executed after the product’s building and delivery, in parallel to the tests execution by engineers and/or users. In this stage, User Stories and Issue Reports are the first documents to be presented. These documents describe, in natural language, business requirements, error scenarios found, expected corrections and enhancements for the system. Its objectives are, among other things, ranking the activities needed to be accomplish during the project. Therefore, in line with the available resources – human, financial and temporal -, it is possible to estimate the effort that will be necessary in the activities development and generate essential information for an effective and efficient planning. As these documents are written in natural texts, it raises the opportunity to use Natural Language Processing and Machine Learning (ML) to predict software effort. In practice, in the daily life of software factories, it is common to use experts’ and project staff’s opinion to judge the effort required by an activity during Planning Poker sessions. Usually, in this technique, the effort is measured in Story Points, which follow Fibonacci sequence. But this planning model requires the scaling of more resources to be executed. The application of ML causes in a system, after the learning phase, the ability to seize the team experience and replicate it quickly and automatically to estimate the activities effort. Thus, this work covers the ML field, proposing a PV-DM Ensemble approach to extract features of Issue Reports to estimate Story Points, the effort indicator. Compared to the two other approaches of BoW and simple PV-DM, the proposed technique has presented good results, about 80% of f-measure, in a supervised learning SVM classifier. The experiments results proved to be a starting point for further study of PV-DM Ensemble approach and its improvement.Item Um guia de boas práticas em desenvolvimento global de software ágil(2023-09-15) Guedes, Rodrigo Gonçalves; Marinho, Marcelo Luiz Monteiro; http://lattes.cnpq.br/3362360567612060; http://lattes.cnpq.br/4064431072353330The Agile Software Development (ASD) plays a pivotal role in the global software development landscape. The COVID-19 pandemic has further underscored the need to adapt agile practices for remote and distributed environments, emphasizing collaboration effectiveness. This study extends prior research that identified 48 agile practices in global projects, reflecting a comprehensive endeavor to analyze and synthesize these practices. We conducted a new survey to gather a broader set of responses and carried out in-depth interviews to correlate data with constructive observations. As a result, 13 agile practices have been identified as the most widely accepted in this context. These practices, such as Planning, Communication, and Self-Management, have proven to be fundamental for the success of AGSD projects. Based on these findings, we have developed an extensive portfolio serving as a reference guide for professionals seeking to implement agile practices in global contexts. This contribution aims to enhance agile software development in global scenarios, fostering superior results and efficiency. As organizations adapt to current and future demands, AGSD stands out as a crucial approach for success in an increasingly interconnected world.Item Liferay Portal Upgrade: definição de um processo eficiente para upgrade de clientes em versões legadas(2022-10-11) Ferreira, Nícolas Moura do Canto; Medeiros, Victor Wanderley Costa de; http://lattes.cnpq.br/7159595141911505Item Sistema de aprendizado de máquina para predição do tempo de esforço de tarefas de desenvolvimento de software(2021-12-14) Sitonio, Tiago Pedro da Silva; Monteiro, Cleviton Vinicius Fonsêca; http://lattes.cnpq.br/9362573782715504; http://lattes.cnpq.br/0915757895643807Item Aplicação de métodos ágeis em desenvolvimento global de software(2021-07-22) Alves, Annelyelthon Ferreira; Marinho, Marcelo Luiz Monteiro; http://lattes.cnpq.br/3362360567612060; http://lattes.cnpq.br/8410367808658970Global Software Development (GSD) continues to grow and is rapidly becoming a standard, fundamentally different from local Software Engineering development. Withal, agile software development (ASD) has become an appealing choice for companies attempting to improve their performance although its methods were originally designed for small and individual teams. The current literature does not provide a cohesive picture of how the agile practices are taken into account in the distributed nature of software development: how to do it, who, and what works in practice. This study aims to highlight how ASD practices are applied in the context of GSD in order to develop a set of techniques that can be relevant in both research and practice. To answer the research question, ”how are agile practices adopted in agile global software development teams?” We conducted a systematic literature review and a survey with practitioners of the ASD and GSD literature. A synthesis of solutions found in seventysix studies provided 48 distinct practices that organizations can implement, including ”collaboration among teams”, ”agile architecture”, ”coaching”, ”system demo” and ”test automation”. These implementable practices go some way towards providing solutions to manage GSD teams, and thus to embrace agility.Item Verificação eficiente de robôs educacionais(2021-03-03) Correia, Lucas Francisco Pereira de Gois; Nogueira, Sidney de Carvalho; http://lattes.cnpq.br/9171224058305522; http://lattes.cnpq.br/1957154709677653Educational robotics is an area of growing interest within educational institutions. Due to it's low cost, program environments for virtual robots have been developed to support the teaching of computing, programming and robotics concepts. The main debug tool available in such environments is the simulation of the robot within a virtual map. Debugging is performed by observing the robot moving across the map: it is not possible to analyze automatically if a program will manage to conclude a specific objective. Approaches to automatically analyze virtual robots are an important teaching tool for an eficient and accurate evaluation of robots. The objective of this project is to improve an automatic verification approach of robot programs. This approach translates programs in the ROBO language to the formal notation CSP and uses the FDR model checker to automatically analyze the program's behavior. The result returned by the model checker is used to inform if the analyzed program has the expected behavior. The main improvement proposed by this project is the implementation of a ROBO to CSP translator that generates a more eficient CSP model to be analyzed, if compared to the model produced by the previous translator. We could observe, through empirical evaluation, a significant reduction in the time to analyze the CSP models obtained from the new translator. The proposed translator presents an almost constant analysis time for the maps considered in the empirical evaluation, while analysis time of the models produced by the previous translator shows an exponential growth in relation to the map's size where the program is analyzed. Another contribution of this work is that the new translator accepts ROBO programs with any command of the language, while the previous translator could only deal with a subset.Item Engenharia de requisitos ágil: extensão de uma revisão sistemática da literatura(2021-02-24) Menezes, Renato Vieira de; Sampaio, Suzana Cândido de Barros; http://lattes.cnpq.br/0066131495297081; http://lattes.cnpq.br/5357825214092807The recent daytoday reality of software engineers is determined by the practice of agile methods, motivating frequent questions in the community about how to adopt a more flexible and dynamic Requirements Engineering (RE), distinct from the traditional model. Agile methods do not have rules established for a single definition of how Requirements Engineering activities should be carried out. Exploring the advances of agile RE in diverse and challenging environments makes it suitable. Therefore, the objective of this Course Conclusion Paper (CCP) is to identify and understand the current scenario of the variety of use of practices / techniques that compose such activities, the important challenges and lessons learned. An extension of a systematic literature review study was conducted to carry out this analysis and the evidence is synthesized from sources published between 2017 and 2020. In addition to verifying, describing and directing the research regarding Agile Requirements Engineering, the work delivers a compiled of practices, observing the different contexts of projects and organizations.Item Scaling agile methods in global software projects: Is it possible with SAFe?(2020-09-03) Figueredo, Rafael da Camara; Marinho, Marcelo Luiz Monteiro; http://lattes.cnpq.br/3362360567612060; http://lattes.cnpq.br/1583800948677235Global Software Development (GSD) continues to grow substantially and it is fast becoming the norm and fundamentally different from local Software Engineering development. Withal, agile software development (ASD) have become an appealing choice for companies attempting to improve their performance although its methods were originally designed for small and individual teams. Despite it, agile practices in Global Software Development (AGSD) has become the main option to execute projects in distributed environments due to its benefits of better communication and coordination, improved productivity, and quality. However, while organizations continue to grow, the complexity and challenges arise fast, many companies are dealing with large-scale global projects and looking for how to adapt agile in those scenarios and scaling agile practices to coordinate them. The current literature does not provide a cohesive picture of how the agile practices are taken into account in the distributed nature, and also how to scale than in large-scale AGSD projects. It lacks data on how to use agile and also scale it in GSD settings, which agile and scaling agile practices work in Global Software Development (GSD) teams and who are supposed to apply them. Based on this literature gap, this study aims to highlight how ASD practices are applied in the context of GSD to develop a set of techniques that can be relevant in both research and practice. Furthermore, it also aims to highlight a set of agile practices that are used by GSD teams to scale agile and map those practices with Scaled Agile Framework (SAFe). To answer both of the research questions, first: “How agile practices are adopted in agile global software development teams?”, second: “Which practices reported in AGSD literature embrace practices from SAFe when adopting scale agile development?”. It was conducted a systematic literature review of the ASD, GSD, and AGSD literature. A synthesis of solutions found in seventy-six studies provided 48 distinct agile practices that organizations can implement in globally distributed settings. Furthermore, from those 48 agile practices, it was possible to identify 18 scaling agile practices embrace SAFe practices. These implementable practices go some way towards providing solutions to manage GSD with agility, while the linked SAFe practices provide guidelines for better scale agile in large-scale global projects.Item QA Metrics: integração das métricas de qualidade de software, em ambiente Docker, para exibição de dashboards Grafana alimentado pelo banco de dados temporal InfluxDB via Newman(2022-07-15) Silva, Lucas Ferreira da; Bocanegra, Silvana; Assad, Rodrigo Elia; http://lattes.cnpq.br/3791808485485116; http://lattes.cnpq.br/4596111202208863; http://lattes.cnpq.br/9075508106025707Software Quality metrics and indicators are able to help a software tester, commonly known as QA, to assess what needs to be done to improve performance of a software development project. In addition, it makes it possible to monitor the progress of a project in order to suggest initiatives based on the collected data. However, gathering the metrics obtained from different data sources to present them in real time is not an easy task for some companies. Nevertheless, with the use of APIs, it is possible to collect the data, analyze and present them in dashboards and reduce QA rework. In this paper, it was developed a system capable of collecting data from three services in order to present, in dashboards, the metrics that are essential in the area of Software Quality. Furthermore, the collection and storage of these metrics are performed in an automated and orchestrated manner through a compact, fast, efficient, safe, portable and isolated application.Item Os efeitos da (in)felicidade no processo dedesenvolvimento de software(2019) Falcão, Tiago Coutinho; Marinho, Marcelo Luiz Monteiro; http://lattes.cnpq.br/3362360567612060; http://lattes.cnpq.br/8796523691341550In the software development process, the main actor responsible for directly impacting production is the individual.With the increase of literature and professional experiences,as well as the importance of studying the human being, recent studies involving the human aspects in software engineering seek to relate psychological factors with exact sciences. Studies show that emotions such as (un) happiness in a software development environment are directly linked to software quality, affecting developer performance.Understanding happiness and unhappiness can be worked out in ways that improve work environment, productivity, and developer motivation. This paper aims to identifythe effects of (un) happiness on the performance of software developers operating in the state of Pernambuco. In this paper, we will analyze the effects and moderating fac-tors that influence the performance of developers when they are happy and un happy during the software development process. Based on a literature review and the opin-ion of those involved in software development, through a questionnaire, which was at-tended by 71 developers, the moderating factors capable of emotionally influencing theindividual leading to the improvement or worsening of their performance were raised.These include: negatively influencing mental and physical health and team motivation as a positive moderating factor.Although some companies have flexibility in many ways such as clothing, coffee breaks and leisure spaces, developer attention is often not explored individually. In this paper, we can conclude that factors such as Mental Health prove that care for the well-being of the individual is extremely important for the proper functioning of the development process.
