In recent years, changes have been made in the development of information systems software for a more agile way of working. Agile teams are responsible for obtaining requirements in a multidisciplinary set, where the business part and the development part are represented in a single project. DevOps is a new movement that tries to improve agility in service delivery. It encourages greater collaboration and communication between development teams and operations and prevents problems and operational needs from being exposed in the project, affecting software quality. For large and cross-platform businesses, it is essential to consider the mainframe in these tool chains because data and mainframe applications are among their strategic digital assets. The ideal architecture for mainframe inclusion harmoniously combines the specificity of the well-integrated mainframe / task platform (DevOps) into the broader environment of the development and operations chain. Inclusive tooling chains generate a significant competitive advantage by enabling you to have quality information from the mainframe code, making the platform much more accessible to DevOps equipment. Thus, the main problem of the work is: what are the main benefits that would lead a company's IT area to invest in the implementation of bimodal IT with DevOps, aiming to optimize processes?

This study provides empirical evidence to the body of knowledge in Agile methods adoption in small, medium, and large organizations in the global context. This research explores facilitators and inhibitors of Agile methods adoption in software development organizations. A survey was conducted among Agile professionals to gather survey data from 52 software organizations in seven countries across the world. This study found many facilitators of Agile adoption to be significant such as customers' dominant issues, encouragement, project champion, highly competent team, use of tools, etc. Similarly a correlation analysis revealed multiple inhibitors as significant: absence of a full set of right Agile practices, absence of customer presence, absence of tracking mechanisms during Agile progress, and failure to determine the role of the client. The present study identifies that an Agile team with high expertise and competence leads to higher quality in software, customer satisfaction along with return on investment (ROI) while a small Agile team increases ease in handling changing requirements, customer satisfaction, reduced delivery time, and increased ROI. Frequent delivery accelerates better control over work, adds to software quality, customer satisfaction, and in shortening delivery time along with increase ROI. It has also been observed that providing essential features early leads to increase in software quality and customer satisfaction. This study confirms that active customer focus leads to better control over work. Further, absence of customer decreases dealing with changing requirements, and customer satisfaction while absence of progress tracking lowers customer satisfaction. [ABSTRACT FROM AUTHOR]

Software quality plays an important role in the easy and quick adoption of a software product by the end users. Agile methods have proven to play an effective role in ensuring software quality; however, the public sector is hesitant in its adoption. This study evaluates the adoption of agile methods in the public sector in-house software development and capitalization of potential benefits. A quantitative approach is used with 28 survey questionnaires based on budget, time, quick debugging and correction, maintenance, easy testing, and installation as software quality components to assess the employability of agile methods. The questionnaire was served to 216 information technology (IT) professionals (project managers: 6%, developers: 61%, quality assurance (QA) leads: 8%, and testers: 25%) from the public sector companies having experience in software development using agile and waterfall methods. The quality components and hypotheses are evaluated using the T-test and chi-square test, respectively, with a 95% confidence interval. The results highlight the benefits of using agile methodologies for software quality components in the public sector. Additionally, the findings demonstrate how agile software development approaches significantly affect the quality of software products and successful delivery within budget and deadline.

A test case is a cornerstone of the testing process; hence, it is quintessential to ensure the quality of the test cases. However, test case design in the Agile testing process has limitations that affect its quality standards, leading to the failure of many software projects. Previous studies are limited in providing a clear guideline for assessing the test case quality. However, evaluating the quality of test cases will help software testing practitioners to understand some critical issues in designing test cases from various perspectives. Therefore, this paper aims to present the verified factors and criteria of test case quality by software testing experts in an Agile environment. The proposed factors and criteria were verified through expert review techniques, which included an online survey of professionals and those in domain and knowledge experts. Twenty-three industry practitioners, including developers, testers, and systems analysts, were used to identify the domain experts. In contrast, the knowledge experts were drawn from 13 academic areas of software engineering and testing. The results showed that the quality of test cases is paramount in Agile projects; therefore, the experts accept seven factors and 32 criteria with a few mod- ifications and suggestions. The finding may assist the researchers in improving the proposed factors and criteria for validation purposes. Hence, may contribute to soft- ware testing practitioners as a guideline in constructing, designing, and assessing compelling test cases. Most significantly, the fixed factors and criteria may contribute to the body of knowledge in the software testing domain and industries. [ABSTRACT FROM AUTHOR]

The main objective of the present study is to develop a mobile application that manages and controls the entry and exit of bike users (students, faculty, and administrative staff) at the Cooperative University of Colombia (UCC, in Spanish), Bogota campus. Unified modeling language (UML) models are applied to improve software quality by using appropriate metrics and software requirements to control the entry and exit of bike users through a mobile application with up to date technologies (Ionic and Angular). The agile Scrum process is used to obtain the software product to control access to the university through a web application and an app. It is concluded that the software developed here responds to the needs of the university by improving control over on campus bicycle parking.
