Sistemas integrados de gestão empresarial e as transformações no gerenciamento e organização do trabalho: um estudo de caso múltiplo

Abstract

Abstract: This research analyzed the changes that occurred in the planning and organization of work as a result of the implementation of an integrated business management solution (ERP - Enterprise Resource Planning), in two large Brazilian companies, one of which is a private sector industry and the other a public sector service company. The case study was elaborated from four propositions that investigated alterations regarding the centralization of control and distribution of responsibilities, the reduction of people and hierarchical levels, the increase in the workload and the need for additional training. The propositions were elaborated from results obtained in previous researches, carried out in Brazil and abroad. Data were obtained from interviews with project managers and change managers from each company and nine area managers, in addition to the application of a Likert scale questionnaire, in a sample of one hundred and seventeen users from both companies. The interviews made it possible to deeply assess the changes that took place and their motivations. From these data, lists were created that relate the changes found, such as the list of eliminated functions and activities, necessary additional training, changes in the IT area, among others. The data obtained from the questionnaires were analyzed using the statistical software SPSS (Statistical Package for Social Science). In addition to the frequency analyses, a factorial analysis was carried out, which led to the perception of new groupings of factors, more refined than those proposed from previous research. A discriminant analysis was also performed on the sample. The results showed that some users' answers differ depending on the company and the area where they work, the function performed, the time in the company and the educational level. The research showed that the implementation of an integrated management solution led to changes in the management and organization of work in the two companies surveyed, confirming the previously established propositions, except for the reduction of hierarchical levels, which was not confirmed in these companies.
