A racionalidade limitada das decisões de investimento em tecnologia da informação

A literatura sustenta que a tecnologia da informacao (TI), quando adequadamente combinada com outros recursos internos, pode desenvolver caracteristicas dificeis de ser imitadas pela concorrencia. Entretanto, nem sempre isso e facil de conseguir. Alguns casos emblematicos de insucesso que envolve empresas proficientes nas melhores tecnicas de aplicacao da TI nos negocios estimulam uma analise mais atenta sobre os mecanismos da geracao de valor para o negocio. Neste artigo, revelamos os resultados de um estudo de casos multiplos, incorporados em organizacoes proficientes, para a compreensao do valor da utilizacao da TI e discutimos proposicoes sobre o porque de algumas organizacoes apresentarem resultados superiores a outras. Nossa analise indica que a efetividade alcancada pelo uso da TI esta de fato relacionada com a habilidade dos gestores de identificarem ineficiencias economicas previas na dinâmica dos negocios e mitiga-las pela aplicacao da TI, o que nao e conseguido com as tecnicas de analise de investimento atualmente empregadas.

Antecedentes da adoção da computação em nuvem: efeitos da infraestrutura, investimento e porte

Cloud computing, a peculiar form of storage and of making information available, has attracted much interest for its potential to significantly alter required investment in information technology infrastructure. As a paradox, while organizations can benefit from the possibility of implementing cloud computing, decision makers are faced with the dilemma arising from the possibility that competitors will have access to previously scarce or unique resources, essentially sources of competitive advantage. The question that arises is whether cloud computing increases the complexity of investment decisions or, in contrast, simplifies the analysis by allowing resources to be released for investment in other skills required by the business. This research investigates what antecedents are associated with the decision to undertake cloud computing and evaluates the effects existing IT infrastructure and the size and amount of investments have in this decision. Analysis of secondary data was used to develop a structural model, which is accompanied by explanations of the relationships uncovered. This papers contributions include a theoretical explanation of the quandary related to IT investments within this context and the decision to adopt cloud computing and, additionally, the presentation of some managerial implications of these findings. Research limitations and suggestions for changes in future studies are also presented.Cloud computing, a peculiar form of storage and of making information available, has attracted much interest for its potential to significantly alter required investment in information technology infrastructure.

Validade e confiabilidade de instrumento de avaliação da docência sob a ótica dos modelos de equação estrutural

This article describes a study on the features concerned with the validity and reliability of the faculty evaluation tool by using corroboratory and exploratory factorial analyses tecniques. The first hypothesis put forward is that the faculty evaluation model of the Universidade do Sul de Santa Catarina consists of eight correlated dimensions: requirement, evaluation, content, method, professor-student rapport, productivity, ethics and professor-course rapport. Corroboratory studies, however, have shown that the model displayed some inadequate statistical indexes. By re-evaluating the structure of the tool through an exploratory factorial analysis technique, a structure with only four correlated factors; competence, rapport and ethics, motivation and evaluation, became evident. This structure, put to the test through corroboratory analysis techniques, showed indexes of global, incremental and parsimony adjustments as being ideal from the statistical standpoint.

Gestão de recursos do EAD: como adequar as tecnologias aos perfis de assimilação

Online Distance Learning managers face the dilemma of using new Information and Communication Technologies (ICT’s) effectively and efficiently. On the other hand, learning theories, among them Cognitive Psychology, describe how the media and processes affect individual learning. Based on these theories, we propose that individuals can be classified according to their assimilation profile in two groups: Analytical Assimilation and Relational Assimilation. We analyze how different distance education technologies, classified as Textual, Audio, Interactive (synchronous) and Collaborative (asynchronous), affect the perceived effectiveness of technology learning of each group. Empirical evidence support that each group perceives differently technologies types in regard to its effectiveness in learning. Important managerial implications for the effective and efficient use of resources in distance education are proposed.

O desafio da avaliação de equipes de alta capacitação e autonomia: o caso do credenciamento de docentes na pós-graduação

A avaliacao de equipes de alta capacitacao e autonomia representa tradicionalmente um grande desafio para os gestores das organizacoes. Em particular, quando a estrategia da organizacao demanda o realinhamento da equipe, o sucesso da iniciativa pode nao ser facilmente atingido mesmo que os gestores disponham de alto poder coercitivo, uma vez que os processos sao executados com autonomia pela equipe, tornando dificil a efetiva monitorizacao e controle, dificuldade que se potencializa pela alta capacitacao dos membros da equipe. Adicionalmente, o emprego do poder coercitivo pode ter o reflexo negativo da queda do desempenho pelas reacoes individuais ou articuladas, tipicas da resistencia a mudanca. Consequentemente, o comprometimento dos membros de uma equipe de alta capacitacao e autonomia pode requerer o uso de tecnicas que atendam a necessidades individuais como a manutencao do nivel de reconhecimento previo junto ao grupo. Este trabalho trata da apresentacao de tecnica que simultaneamente permite objetivar o alinhamento da equipe e promover o reforco de percepcoes importantes para o comprometimento de individuos com esse perfil tais como reputacao, autonomia e estabilidade, que contribuem para o sucesso em acoes que alinhem individuos aos objetivos da organizacao, reduzindo a resistencia a mudanca. O trabalho discorre sobre os aspectos teoricos da tensao gerada pela necessidade de alinhamento de uma equipe com essas caracteristicas e as implicacoes no nivel do individuo, apresentando em seguida uma proposta de conducao dessa situacao conduzida com base no metodo de pesquisa-acao em um programa de pos-graduacao stricto-sensu no Brasil.
