No. of bitstreams: 1 Angelica Aparecida Gheller.pdf: 2718845 bytes, checksum: f9f4c521bf4c3d6860e62f70ee4b1799 (MD5) Previous issue date: 2017-04-16 / The main objective of this research was to investigate the critical success factors for cloud ERP projects in the scenario of Brazilian companies. In addition, the secondary objectives were to identify the perception of benefits resulting from this implementation, in the aspect of improving organizational performance and the elaboration of a matrix to support the management of such projects, based on a review of the literature and the data collected from the field research. The method of the data collection was a self-directed questionnaire, and the statistical method was the canonical correlation, to answer the main research question. In addition, a factorial analysis and a multiple linear regression were run to investigate possible relationships between the independent variables (critical success factors) and the dependent variables (benefits) of the research model. The results obtained did not validate all the critical factors present in the literature, and those that were proven empirically were regrouped in new dimensions, being: security information and alignment of compliance, and communication and management of stakeholders. / O objetivo principal deste estudo foi explorar os principais fatores críticos de sucesso de projetos ERP cloud, no contexto do cenário de empresas brasileiras. Adicionalmente, os objetivos secundários consistiram na identificação da percepção de benefícios resultantes dessa implementação, sob o aspecto de melhoria do desempenho organizacional e a elaboração, com base na revisão da literatura sobre o tema e nos dados coletados na pesquisa de campo, de uma matriz para apoiar a gestão de projetos dessa natureza. Para responder à questão de pesquisa, o método de coleta de dados foi o questionário autodirigido e o método estatístico foi a correlação canônica. Adicionalmente, foi realizada uma análise fatorial e uma regressão linear múltipla para investigar com mais profundidade possíveis relações entre as variáveis independentes (fatores críticos de sucesso) e as variáveis dependentes (benefícios) do modelo de pesquisa. Os resultados obtidos não validaram todos os fatores críticos presentes na literatura, e os que se comprovaram empiricamente foram reagrupados em novas dimensões, sendo: segurança da informação e alinhamento do compliance, e comunicação e gestão de stakeholders.

Current trends in ERP system were studied by conducting research and analyzes to see to what degree are current ERP trends reflected in existing ERP solutions that are being developed by both Czech and multinational vendors. For the purposes of the research a set of hypotheses was formulated and used to analyze the selected solutions. The research found two trends that are represented in the majority of selected ERP solutions. The application of cloud computing technology and the suitability to use particular solutions as two-tiered ERP. It was also found that all researched vendors to a certain degree implement the principles of Green ICT, although no vendor specifically labeled their software as Green ERP. It was also found that the term Social ERP doesn't appear to be an acceptable term for ERP vendors, although Social ERP functionality of some degree was found to be present in ERP solutions from multinational vendors.

This thesis is focused on the use of enterprise information systems (ERP) provided as a service (SaaS) together with mobile technologies in an enterprise with logistics activities. The goal of the thesis is to find out whether a Czech market offers the ERP provided as a service suitable for needs of the model enterprise. This is achieved by specifying a set of criteria and following comparison and evaluation of the chosen ERP systems in two phases. The result is one chosen system which suits the best to specified criteria and therefore the needs of the model enterprise. Subsequently for the chosen system (and its offered func-tionalities) possibilities of its use with mobile technologies are described for model enterprise processes.

This thesis is focused on cloud computing and its impact on enterprise resource planning information systems. The historical background of cloud computing is discussed in the first of the thesis. After that, analysis of all possible services and types of cloud computing are provided. In this first part of this thesis, there is also an analysis of cloud computing providers who provide one of the possible cloud computing service - Infrastructure as a Service(IaaS). This thesis evaluates IaaS providers based on suggested methodology. According to this methodology each provider is ranked and the provider with the highest score is used as a provider for outsourcing infrastructure for a new model of information system which is suggested further in the thesis. The next part of this thesis provides a detailed view on cloud computing service closely related to software distribution - Software as a Service(SaaS). This focuses on key features of this approach, there is a discussion about differences between ASP and on-premis approach. At the end of this part there is a detailed discussion about SaaS benefits and risks for customers as well as software vendors. Having discussed all necessary theoretical background a local software company providing mainly on-premise enterprise resource planning information system is described. After all threads and opportunities of this company are analyzed it is suggested to provide a new option of distributing one of its information system to customers - in the form of SaaS. Based on the decision in the previous part, one of the information systems offered to customers is chosen and reengineered in order to allow distribution over the Internet as SaaS. While changing the architecture of the information system, the main focus is to reduce initial costs. A necessary features which need to be changed are analyzed from three perspectives - technological, process and economical. In all of these perspectives there is a discussion about problems which need to be kept in mind. Each problem is analyzed and the solution options are discussed. Towards the end of each problematical part there is a recommendation for the company in order to reach the set goals. The final part is comparing the on-premise system and the SaaS system. The comparison is provided in the customer example. There are calculations for each solution and a discussion about potential attractiveness of a newly designed information system for potential customers.

This thesis focuses on an assessment of the current information system in a small company followed by a plan proposal for its replacement. Main goal is to compare multiple different approaches to the process of implementing a new information system in a company and the use of methodical approach for their comparison. The result of this should be a recommendation to whether the information system should be replaced and if so, what will be the resulting gain for the company.
