M-learning (mobile learning) in practice: a training experience with it professionals
Get PDFThis paper presents the results of a study that addresses the following question: what are the real possibilities of m-learning (mobile learning) for the development of individual competences and also for collaboration in the organizational setting? The paper analyzes a real experience in m-learning for training IT professionals. For this purpose a mobile virtual learning environment called COMTEXT was developed and implemented, which was designed to support competence development for workers using PocketPCs. The participants of the training activity (13 professionals) evaluated the m-learning experience via a structured questionnaire; all the content and interactions within COMTEXT were analyzed via content analysis. The results generated important insights into the ergonomic, technological and pedagogical possibilities and limitations of mobile and wireless technologies for corporate training and also on methodologies and learning tools that can be applied to m-learning. As an exploratory study, it also indicates issues for further research on m-learning in the organizational context
Project orientation: a proposal to develop a service-oriented architecture
Get PDFA arquitetura orientada a serviços (SOA) é ocasionalmente encarada como um desafio complexo e intransponível (Serman, 2007), sentimento motivado pela falta de atenção de praticantes e da academia sobre os meios para sua construção. O trabalho visa trazer a gestão da carteira de projetos de TI como opção para orientar o desenvolvimento de SOA. Para isso, realizou-se uma revisão da literatura sobre SOA, incluindo estudos de caso sobre sua adoção. Também foi executado um estudo de caso, no qual foram analisados os projetos de uma determinada organização, focando-se na evolução de sua arquitetura de serviços. Os resultados mostram a construção gradual de SOA no caso a partir da conclusão e sucessão dos projetos. Conclui-se com uma proposta de processo de construção de SOA e as limitações e sugestões de pesquisas futuras.A service-oriented architecture (SOA) is occasionally seen as a complex and undefeatable challenge (Serman, 2007). This feeling is motivated by the lack of attention from practitioners and from the academy on the means for its construction. The work aims to bring the portfolio management of IT projects as an option to guide the SOA development. A review of the literature on SOA was carried out, including case studies on the SOA adoption. A case study was also done, which analyzed some projects of a particular organization, focusing on the evolution of its services architecture. The results show a gradual development of SOA in the case studied based on projects execution and sequencing. It concludes with a proposal of a process for building SOA as well as suggestions and limitations for future research
The practice of knowledge management in a rentail familiar company in Minas Gerais (MG): a case study
Get PDFAs empresas familiares têm ocupado papel de destaque nas economias nacionais e, em especial, na brasileira. Apesar de sua importância, a viabilidade dessas empresas é questionada. Boa parte de tais questionamentos tem como principal fundamento as limitações gerenciais comumente observadas na gestão de organizações familiares. Tem-se, portanto, que a busca por soluções de ordem gerencial é uma questão urgente para a sobrevivência de empresas familiares. Na miríade de estratégias organizacionais, hoje existentes, a gestão do conhecimento tem despontado como um importante diferencial competitivo. Neste sentido, o objetivo desse artigo foi verificar como ocorre a gestão do conhecimento (GC) em uma empresa familiar do ramo varejista em Minas Gerais. Foi realizado um estudo de caso qualitativo, cujos dados foram coletados por meio de observação e entrevistas em profundidade com gestores. Os resultados indicaram a existência das seguintes práticas de GC (JÓIA e OLIVEIRA, 2007): troca de conhecimento em reuniões, grupos de estudo, incentivo a inovação e disseminação do conhecimento via contato pessoal. Concluiu-se que, na organização estudada, a GC é favorecida, em função da existência de ambiente propício à inovação, criatividade e compartilhamento do conhecimento tácito.The Family Companies have an important role in national economies and, specially in the Brazilian one. However its importance and feasibility are questioned. Good part of such questionings has a focus on the managerial limitations often observed in the management of Family Organizations. As a consequence the search for solutions under the managerial scope is an urgent issue for the survival of Family Companies. Within the myriad of current organizational strategies, knowledge management has emerged as an important competitive differential. Following this track, the objective of this article was to verify how knowledge management (KM) in a rentail Family Company in Minas Gerais (Brazil) occurs. A qualitative case study was carried through, based on data obtained from observations and interviews with managers. The results led to KM\u27s practices (JÓIA and OLIVEIRA, 2007): exchange of knowledge in meetings, study groups, incentive to innovation and dissemination of knowledge by personal contact. The conclusion highlighted how much the company\u27s environment favored KM\u27s practices due to the a favorable field for the development of innovation, creativity and sharing of implicit knowledge
An information sub-system model for the utilization of the receipt printer as a management instrument in the supermarket sector in the State of Santa Catarina
Get PDFThe supermarket sector in the State of Santa Catarina, as well as other sectors, has invested in technology and information systems. Public authorities make legal requirements about this sector which, at first, serve only as fiscal control, as in the case of the Receipt Printer-RP. This paper aims to demonstrate how the RP is used in the companies studied. It also aims to show the feasibility of the RP as a tool for management purposes, with results in reducing expenses, costs and tax charges, by means of specific reports. An information subsystem model will be considered as a management tool with the use of the RP. The methodology adopted was quantitative, with an exploratory and deductive study. The universe of this study is the supermarket sector in the State of Santa Catarina, using a sample chosen by the invoicing criterion. The database was formed by questionnaires sent to the sector and other information provided by public agencies, through the use of special data from the State Department of Finance, which is responsible for the control of RPs. Results indicate that it is possible to use the RP as a management instrument
A comparison of erp-success measurement approaches
Get PDFERP projects are complex purposes which influence main internal and external operations of companies. There are different research approaches which try to develop models for IS / ERP success measurement or IT-success measurement in general. Each model has its own area of application and sometimes a specific measurement approach based, for instance, on different systems or different stakeholders involved. This research paper shows some of the most important models developed in the literature and an overview of the different approaches of the models. An analysis which shows the strengths, weaknesses and the cases in which the specific model could be used is made
Evaluation of the Globo. com portal efficiency: a case study in light of the fuzzy set theory
Get PDFO surgimento da Internet revolucionou a forma das pessoas se comunicarem. Entretanto, com a quantidade de alternativas de websites é comum os internautas se sentirem perdidos e, muitas vezes, frustrados em não alcançarem seus objetivos. Assim, este artigo tem como objetivo o desenvolvimento de um modelo que seja capaz de avaliar o grau de flexibilidade e de eficiência ao uso da página Globo.com, como uma das medidas de usabilidade consideradas por Nielsen.
