    Agile web development with scrum: A user experience based approach using linguistic metamodel
    (2018-07-15) AGUILLAR, D. A. M.; Plinio Thomaz Aquino Junior
    © 2018, Springer International Publishing AG, part of Springer Nature.In this work it is proposed an approach based on user experience design for the agile development of web-based software, using the language metamodel. The main motivation was the observation of evidences, in market studies and papers from other researchers, of proportional differences between the usage of agile methods versus methods based on user experience design. This research proposes an approach for the development of web applications using SCRUM, based on UX design, offering the metamodel as a tool to tackle communication problems during this process. The experiments were done in academic and industrial contexts in order to validate and check viability/applicability of the proposed approach: In the academic context, workshops were made for the practical application of the developed approach and information regarding the experiment was collected by means of questionnaires. It was demonstrated that the proposed approach may be viable and may be applied in contexts where it is possible to adopt all stablished recommendations and principles so that the integration between SCRUM and UX happens. It was also used as a facilitating tool, for the integration process, the linguistic metamodel to permeate all existing communication processes, reducing communicational noise related to omission, generalization and distortion of information.

    Small brazilian business and IT governance: Viability and case study
    (2018) AGUILLAR, D. A. M.; MURAKAMI, I.; MANSO, P.; Plinio Thomaz Aquino Junior
    © Springer International Publishing AG, part of Springer Nature 2018.Small companies have potential to be agile, flexible and informal - this is possible because such companies are usually formed by few members (up to 9 people – statistic average in Brazil). This usually creates more synergy among these professionals because they incline to have more than a single role inside the company. Therefore, it is understandable that those professionals should multi-task, splitting their working hours among different kinds of demands: what may cause difficulties in planning, development, verification, and improvement of internal processes. This article brings a case study where the COBIT 5.0 toolkit (Process Assessment Model) was used to identify internal processes that needed improvement within the studied company. In order to improve the selected processes, ISO/IEC 12207 was tailored concerning company’s needs. Additionally, it was applied a continuous improvement cycle – PDCA and it was also proposed the adoption of an agile method – SCRUM, to integrate internal activities and processes.
