“…At first, we defined our sample and conducted observational research by analyzing the website content frequency and disposition and comparing it with previous classifications in theory. This procedure is commonly used by researchers in the technological field by building a counting checklist of items identified in websites and applications (Pinterits et al (2006), Stepchenkova et al (2010), Tezza et al , 2016; Tezza and Vargas, 2012). These data were analyzed by content analysis.…”

Purpose This study aims to expand previous work on website stage models by proposing a new model including a dimension encompassing digital integration and the context of mobile, digital marketing and new technologies. Also, this study aims to classify Brazilian wineries using the stage model proposed and verify if the designated stages influence the wineries’ presence in digital and mobile media. Design/methodology/approach Observational research and quantitative content analysis were adopted to examine a sample of winery websites (N = 150) located in different states and regions of Brazil and create a new website stage model. After the new model’s development, the authors conducted a statistic analysis by running a one-factor analysis of variance to assess the influence of the company’s stage in the use of digital media and mobile strategies, as well as its impacts on market development. Findings The results suggested a quite mature market regarding website stage position, even though there is still room for growth and technological innovation. Also, the research findings show that there is a positive association between the company’s stage in the use of digital and mobile media strategies. In other words, the more advanced the winery stage, the greater its digital media and mobile presence. Originality/value While previous studies attempted to identify wineries’ stages through models, this study presents a new approach by updating the past studies’ stages as well as providing and testing a digital media and mobile dimension. This research contributes to consolidating the Brazilian wine industry position regarding its presence in digital and mobile media, bringing reflections to organizations, society and theory development.

“…Thus, the adopted concept of quality in websites is that of a set of technical and non-technical characteristics of a web system, which allow the user to achieve their goals in a website in an accessible, efficient and pleasant way. As technical characteristics is meant usability/navigability, presentation of information, accessibility and interactivity of the application of the Rasch model (Rasch, 1960) for the usability inspection process, Tezza et al (2011) applied the one-dimensional two-parameter logistic model to measure usability in commercial websites and Tezza et al (2016) compare hierarchical and non-hierarchical models in IRTin the context of commercial websites. However, it was not found in the literature the presentation of an interpretable IRT multidimensional model to evaluate the quality of commercial websites.…”

ISSN 0104-530X (Print) ISSN 1806-9649 (Online) Resumo: O presente artigo propõe um modelo multidimensional para medir a qualidade de websites comerciais com uso da Teoria da Resposta ao Item (TRI). A qualidade de um website engloba características técnicas (usabilidade/navegabilidade, apresentação da informação e interatividade) e não técnicas (design, estética, apelo visual, confiabilidade, hedonismo, imagem), configurando-se, teoricamente, como contexto multidimensional. As suposições iniciais das dimensões e elaboração dos itens foram baseadas em análise bibliográfica sobre o tema qualidade em websites de e-commerce. Um conjunto de 75 itens foi elaborado e uma amostra de 441 websites de e-commerce dos mais variados setores foi a ele submetido. O tratamento e análise dos dados foram feitos utilizando-se a TRI. Nessa etapa, foram discutidas questões referentes à dimensionalidade e à escolha do modelo mais adequado. Por fim, um modelo multidimensional com quatro dimensões foi ajustado contemplando as dimensões navegabilidade ou condução/orientação do usuário, acessibilidade e confiabilidade do sistema, interatividade e apresentação da informação.

The quality of a website encompasses technical characteristics (usability-navigability, presentation of information and interactivity) and non-technical characteristics (design, aesthetics, visual appeal, reliability, hedonism, image), theoretically configuring a multidimensional context. The initial hypothesis of the dimensions and the elaboration of the items were based on a bibliographic analysis about the theme of e-commerce website quality. A set of 75 items was prepared and submitted to a sample of 441 e-commerce websites from a wide variety of sectors. The treatment and analysis of data was conducted using IRT. In this step, questions related to dimensionality and the choice of the most suitable model was discussed. Finally, a multidimensional model with four dimensions was adjusted.

“…Instead of this, the evaluation of a site generally depends upon several criteria to capture all dimensions of the final product/service. Therefore, the quality of websites is treated as a multidimensional variable (Tezza, Bornia, Spenassato, & Trierweiller, 2016), although there is not a consensus about what are its dimensions (Ongsakul et al, 2020).…”

Maintaining an attractive, easy-to-use website that stands out in the industry in which it operates is a premise for any business that intends to use the internet effectively. However, users to encounter many problems when interacting with websites, and this is because many organizations do not have a complete understanding of what a website really means to them. Although there is a lot of evidence in the form meta-analysis reviews related to website quality assessment, a systematic review of these meta-analyses is lacking in the literature. Our objective was to synthesize the existing literature to identify the main dimensions and analysis methods associated with website quality assessment. Following the recommendations PRISMA statement for systematic reviews, we reviewed relevant articles identified in the Web of Science and Scopus databases. A total of 38 original research articles related to website quality assessment were retrieved and selected for eligibility. The results present an overview of studies on website quality assessment, identifying the main criteria used for their assessment. Our review shows that there are more than a hundred dimensions used in studies to assess the quality of websites, however, these dimensions have similarities and therefore were grouped, providing a broad view of the most used dimensions.
