Item Design Sprint como ferramenta de apoio ao empreendedorismo e à inovação(Universidade Federal de Goiás, 2021-06-04) Barros Neto, Wagner de; Soares, Júlio Cesar Valandro; http://lattes.cnpq.br/9557844115914458; Bevilacqua, Sólon; Francisco, Roberto da Piedade; Soares, Júlio Cesar ValandroStudies on the business death rate reveal some factors that most cause companies to fail: not delivering the right product to the market and taking too long to develop it. Several methodologies have emerged to support innovation processes and agile development of products, seeking to support teams to test, develop and launch their ideas with greater chances of success. Among them, there is the Design Sprint, a method created within Google, which this dissertation aimed to analyze the effectiveness as a tool to support innovation and entrepreneurship. For that, two action researches were carried out, applying the method in two startups and evaluating the process and its result. Then, a survey was carried out with organizations from 21 countries that adopted the Design Sprint in the creation or improvement of products, services, strategies and processes, evaluating the impacts perceived in terms of time and money savings, as well as impacts on the team, innovation, product and financial. The survey results showed that the method was beneficial for different types of organizations to have more aligned teams, better products, more agile innovation processes and reduced commercial and operational costs. The survey revealed that organizations that applied Design Sprint achieved an average time savings of 2.1 months, with a return of investment on time of more than 10.5 times. The method demonstrated the ability to support companies in different contexts and objectives, and should in fact be analyzed as a possible tool to support innovation processes and development of solutions.Item Avaliação da satisfação do usuário de telefonia móvel da região Centro-Oeste por meio da modelagem de equações estruturais(Universidade Federal de Goiás, 2023-10-24) Oliveira, Juliane de Sousa; Santos Neto, Agenor Sousa; http://lattes.cnpq.br/6615964725213306; Soares, Júlio Cesar Valandro; http://lattes.cnpq.br/9557844115914458; Soares, Júlio Cesar Valandro; Santos Neto, Agenor Sousa; Almeida, Tiago dos Santos; Duarte, Márcio AntônioIn order to maintain competitiveness and profitability, telephone companies seek indices that assess customer satisfaction. Understanding the level of consumer satisfaction regarding the use of mobile phone services is essential, since this type of communication provides ease and is present in the majority of the population. This work aims to present the main factors that impact on mobile telephony user satisfaction in the Midwest Region. This research was developed with the aid of the questionnaire carried out by Anatel. The questions contained in the questionnaire were grouped into the following constructs: Perceived Quality, Expectations, Perceived Value and Global Satisfaction. Structural Equation Modeling was used to assess consumer satisfaction in the Federal District, State of Goiás, State of Mato Grosso and State of Mato Grosso do Sul. Each location got different results. For the Federal District, of the six hypotheses analyzed, two were rejected. For the State of Goiás, of the six hypotheses analyzed, two were also rejected. For the State of Mato Grosso of the six hypotheses tested, only one hypothesis was rejected. The State that obtained the highest number of rejections of the hypotheses was the State of Mato Grosso do Sul, of the six hypotheses analyzed, three were rejected. Of all the hypotheses analyzed, the customer expectation factor proved to be significant and positive in the perceived quality and value perceived by the consumer.Item O método seis sigma como uma evolução do controle estatístico de processos desenvolvimento de um modelo customizado(Universidade Federal de Goiás, 2021-09-20) Pavezzi, Camila Cumani; Soares, Júlio Cesar Valandro; http://lattes.cnpq.br/9557844115914458; Soares, Júlio Cesar Valandro; Guimarães, Núbia Rosa da Silva; Galo, Nadya ReginaStatistical tools are fundamental to reduce waste caused by non-quality in several processes, through the reduction of their variability, highlighting the statistical process control and the six sigma method, which are focused on fast monitoring. Both bring the concepts of control charts, process capability assessment and root cause analysis as drivers of optimization in various sectors, however, according to the bibliometric research carried out, there are still few studies involving such methods combined. In this sense the study brings the relevance of this theme through an application in the food industry, more specifically in the manufacturing of tomato sauces, aiming to study the variability of the formulation parameter °brix, based on the development of a customized model to the process under study that brings greater predictability to the process. To conduct the research, data from a continuous process were collected, control charts and histograms were elaborated, and the process sigma level was analyzed. Statements were also collected from the main actors in the process to evaluate the causes of variability. It was observed that initially, the process was centralized, but with variability outside the control limits, being verified a 4.15 sigma level for the process, generating 0.4% of products outside the design specifications. After the optimization proposals, the process became more centered in its limits, with a 9% reduction in the standard deviation value and a 48% reduction in the number of defects generated, verifying the variability reduction. The entire study was based on the development of a customized model for the process, considering its particularities, with a step-by-step guide on how to apply the combined methods in the organization. Finally, the research demonstrated the relevance and applicability of the SPC and six sigma methods in the scientific field, as a reference for similar studies in this area of knowledge.
