Grau de informatização de empresas: um modelo estrutural aplicado ao setor industrial do estado de São Paulo

Abstract

A difusão do uso da Tecnologia de Informação (TI) é evidenciada por meio de um processo, que pode ser denominado informatização e que permeia nossa sociedade e negócios. Com relação aos negócios, os gestores necessitam de instrumentos para avaliar o uso organizacional da TI. O artigo apresenta um modelo de avaliação com base na mensuração do construto Grau de Informatização (GI). Cinco dimensões (fatores) de avaliação foram consideradas no modelo final: uso organizacional da TI, impactos da TI, atributos das aplicações da TI, infra-estrutura da TI e governança da TI. O modelo foi desenvolvido a partir do levantamento de dados de uma amostra de 830 empresas industriais do estado de São Paulo. Nele, a modelagem por equações estruturais foi utilizada para desenvolver e validar o GI. O construto satisfez os requisitos de consistência e validade interna e demonstrou possuir validade externa na medida em que as proposições em relação ao tamanho da empresa e não quanto aos níveis de investimentos em TI foram confirmadas.

Digital Divide of Small and Medium-Sized Enterprises: An Analysis of Influencing Factors Using the Toe Theory

“…This paper used the ICT use measurement model presented by Siqueira, Souza, and Reinhard (2015a), which evaluates the intensity of the use of ICTs by SMEs from a scale developed using secondary data from the national "TIC Empresas" survey. In order to calculate the index, we considered the ICT use dimensions for internal (vertical and horizontal) integration of the company and the use of decision support tools, according to the IT use model in organizations previously proposed by Zwicker, Souza, Vidal and Siqueira (2007). From the "TIC Empresas 2011" survey, and subsequently from the "TIC Empresas 2013" survey, Siqueira et al (2015a) identified proxies to represent the dimensions of the model (Table 2), and from the microdata of these survey editions and the techniques of factorial analysis and modeling of structural equations by means of a PLS (partial least squares) estimation, the final model was obtained for the index represented in Flowchart 2.…”

IT business value model for information intensive organizations

“…While reviewing the literature on the topic, a number of models and dimensions were found which different authors suggest are capable of representing IT Business Value (Brynjolfsson & Hitt, 1996;Dehning, Richardson, & Zmud, 2007;Gregor et al, 2006;Melville et al, 2004;Radhakrishnan, Zu, & Grover, 2008;Turner & Lucas, 1985;Weill, 1992;Weill & Broadbent, 1998). While some authors emphasize the strategic value of IT (Neirotti & Paolucci, 2007), others call attention to the process of obtaining organizational benefits from IT investments (Zwicker, Souza, Vidal, & Siqueira, 2007). This helps demonstrate how complex is the task of analyzing the IT value.…”
