Uses of ERP systems and their influence on controllership functions in Brazilian Companies
No full textControllership and Information Technology provide ways for companies to adapt to the competitive context of business environments. As such, the aim of this research is to identify and analyze the impacts of ERP systems on Controllership functions, verifying the relationships between the use of solutions and possible improvements in such functions. The need for management control and operations control were observed. This research is descriptive and exploratory of the survey kind. The subjects mentioned in this research are managers involved in Controllership activities in large companies from the Auto Parts sector in the State of São Paulo. The data obtained through a questionnaire by non-probabilistic samples were analyzed with the use of descriptive statistics. According to the subjects, ERP systems modify Controllership functions and better serve the control needs of the operations. The results showed problems to be overcome in management control
Scientific production of entropy and information theory in Brazilian journals
No full textThis article aims at giving an overview of the scientific production about Entropy and Information Theory in national periodical publications in Qualis/CAPES. This article is a descriptive research and a bibliometric study with a quantitative approach. Its sample is composed of 31 articles from periodic publications from different areas, such as: Accounting, Economy, Computer Sciences, Electrical and Hydraulic Engineering, Sciences, Mathematics, Physics and, also, articles that were published in an electronic library called Scientific Electronic Library Online (Scielo) from 2002 to 2009. Among the results, one was able to notice that the "B5" (Qualis Capes) classification has shown a higher number of articles, as well as that 2008 was the year with a higher number of publications
Fuzzy Clustering: application on organizational metaphors in Brazilian companies
No full textDifferent theories of organization and management are based on implicit images or metaphors. Nevertheless, a quantitative approach is needed to minimize human subjectivity or bias on metaphors studies. Hence, this paper analyzed the presence of metaphors and clustered them using fuzzy data mining techniques in a sample of 61 Brazilian companies that operate in the state of Rio Grande do Sul. For this purpose the results of a questionnaire answered by 198 employees of companies in the sample were analyzed by R free software. The results show that it is difficult to find a clear image in most organizations. In most cases characteristics of different images or metaphors are observed, so soft computing techniques are particularly appropriate for this type of analysis. However, according to these results, it is noted that the most present image in the organizations studied is that of "organisms" and the least present image is that of a "political system" and of an "instrument of domination"
Telecommuting and HRM: a case study of an information technology service provider
No full textWith the development in information technology resources, a way of working has been standing out: telecommuting. This manner of working from a distance may offer a competitive advantage in attracting and retaining highly skilled professionals. The purpose of the research presented in this article is to identify guidelines for the implementation and management of telecommuting, as an alternative to overcome the shortage of qualified professionals in Information Technology (IT). The results, based on a case study of a Brazilian subsidiary of a multinational organization that provides IT services, show that telecommuting (1) contributes to attracting and retaining qualified professionals in IT, (2) should be based on trustworthy relationships, (3) has to be supported by a strategy of decentralization of both structure and organizational assets
Digital inclusion (infoinclusion) in Piraí Digital: empirical evidence based on the actor-network theory
No full textO artigo apresenta o status quo do programa Piraí Digital, com base na Teoria Ator-Rede (ANT) e no modelo heurístico de inclusão digital (2iD). Numa primeira etapa desta pesquisa, o modelo heurístico original foi expandido com base nos pressupostos da ANT, gerando uma versão mais adequada (e2iD) para a observação do fenômeno da infoinclusão em Piraí. Em seguida, a ANT foi adotada como suporte metodológico para que os autores, por meio de entrevistas e observação direta, compreendessem, sob a ótica dos atores ouvidos, como a infoinclusão tem ocorrido no município de Piraí. A partir daí, os resultados são apresentados com base na taxonomia da ANT e dos elementos do modelo e2ID. O presente trabalho de pesquisa sobre a infoinclusão em Piraí começou em 2007 e se estendeu até os últimos meses de 2009. Concluiu-se que a inclusão digital em Piraí tem sido uma realidade na administração pública local, na educação e na saúde. Porém, percebeu-se que o setor produtivo e a sociedade civil local, pouco ou nada tem se beneficiado do programa em questão. Finalmente, foi possível compreender o papel dos vários atores públicos nas redes de atores da ANT e explicar porque os resultados de Piraí Digital não têm, até agora, impactado homogeneamente a sociedade local.This paper presents the Piraí Digital status quo, based on the Actor-Network Theory (ANT) and on the heuristic model of digital inclusion (2iD). In the first phase of this research, the original heuristic model was expanded from the ANT assumptions, giving rise to a more suitable version (e2iD), aiming at the observation of the digital inclusion process (infoinclusion) in the City of Piraí. Next, the ANT was adopted as a methodological support so that authors, by means of interviews and direct observation and from the standpoint of the authors interviewed, could understand how digital inclusion (infoinclusion) is developed in the City of Piraí. From that point on, the results are presented based on the ANT taxonomy and on the elements of the e2ID model. This research work about digital inclusion (infoinclusion) in the City of Piraí began in 2007 and extended up until the last few months of 2009. It is concluded that digital inclusion in the City of Piraí has been a reality to the local public administration and to the educational and health systems. Nevertheless, it is noticed that both the productive sector and the local civil society have had few or no benefits from the program in question. Lastly, it is possible to understand the role of the various public players in the ANTs and explain why the results of the Piraí Digital have not homogeneously impacted the local society so far
Management model for the development of software applied to business sustainability in the context of global climate changes
No full textThis article introduces a social and environmental management model based on the results of an empirical study that was conducted using the grounded theory method. It outlines a social and environmental mapping of the different economic segments of the Brazilian business universe to support decisions that are inherent to the sustainable management of the supply chain of organizations in terms of clean development mechanisms. It is in this context that the concept is included for the architecture of software and a model of social and environmental balance to track the demands for carbon credit required by an organization in the scenario of its business and that of the national economy
The 3C cooperation model applied to the classical requirement analysis
No full textAspects related to the users\u27 cooperative work are not considered in the traditional approach of software engineering, since the user is viewed independently of his/her workplace environment or group, with the individual model generalized to the study of collective behavior of all users. This work proposes a process for software requirements to address issues involving cooperative work in information systems that provide distributed coordination in the users\u27 actions and the communication among them occurs indirectly through the data entered while using the software. To achieve this goal, this research uses ergonomics, the 3C cooperation model, awareness and software engineering concepts. Action-research is used as a research methodology applied in three cycles during the development of a corporate workflow system in a technological research company. This article discusses the third cycle, which corresponds to the process that deals with the refinement of the cooperative work requirements with the software in actual use in the workplace, where the inclusion of a computer system changes the users\u27 workplace, from the face to face interaction to the interaction mediated by the software. The results showed that the highest degree of users\u27 awareness about their activities and other system users contribute to a decrease in their errors and in the inappropriate use of the system
Using grounded theory as a method for system requirements analysis
No full textRequirements analysis (RA) is a key phase in information systems (IS) development. During this phase, system analysts use different techniques and methods to elicit and structure the system\u27s requirements. The current paper rationalises the use of grounded theory (GT) as an alternative socio-technical approach to requirement analysis. It will establish theoretically that applying grounded theory procedures and techniques will support and add value to the analysis phase as it solves some problems of the existing traditional and socio-technical system design methods. Furthermore, to validate this proposal, a case study applying GT on a real project will demonstrate its applicability and success for requirement analysis. Implications of its application are also discussed
Value creation from organizational project management: a case study in a government agency
No full textThis paper aims to analyze, through a case study based on a construct of the work of Thomas and Mulally (2008), called Researching the Value of Project Management, the relations of the constructs of this conceptual model and to show how they interfere with the organizational values, possibly in programs conducted by a government agency, from the perspective of the senior management directly involved. The analysis of information collected indicated that project management has brought value to the organization, but not all components of the conceptual model used were perceived. Additionally, differences between respondents from outside and inside of this department become evident, indicating a difference in stakeholders´ interests. Finally, from the perspective of institutional isomorphism, we searched for evidence of an effort to increase the organization\u27s management maturity in project management, indicating by documents the mimetic and coercive isomorphism to ensure the achievement of goals and financial efficiency of the projects analyzed
Benefits and success factors of open-source web services development platforms for small software houses
No full textIt is usually difficult for companies to keep up with the development of new information technologies and adapt to them in face of the opportunities and threats their advances may represent. This is especially true for small and medium enterprises (SME) in emerging economies, where resources tend to be scarce and markets more volatile. This paper describes an action research conducted in a small Brazilian software house that adopted an open-source Web Services development platform in order to improve its software development process. Data analysis revealed critical success factors (CSF) in the adoption process, as well as specific benefits and barriers prone to be faced by small software houses in their adoption efforts. In the process of overcoming such barriers, SME may acquire intellectual capital that represents an essential resource to ensure their competitiveness and survival in emerging economies
