Web engineering for the evaluation of large complex web systems: methodologies in web metrics

Roaming the Internet, users sometimes encounter severe problems or feel dissatisfied using a particular site. E-government websites are the public gateways to access information and services but there is still no agreement on how to assess a government’s online presence. Failure of e-government projects in achieving their goals is common and there is uncertainty about how best to evaluate an e-government website. It has been argued that existing evaluation frameworks have some methodological limitations and they mostly neglected citizens. There is a lack of an engineering approach for building web systems and the literature on measuring the quality of website is limited. There is an uncertainty in the selection of evaluation methods and some risks of standardizing inadequate evaluation practices. Managing the complexity of web applications, Web Engineering is emerging as a new discipline for the development and evaluation of web systems to promote high-quality websites. But web quality is still a debatable issue and web metrics is considered a valuable area of ongoing research. Therefore this research focuses on the methodological issues underlying web metrics and how to develop an applicable set of measurement for designing websites. The main aim is to create new metrics for web engineering and develop a generalizable measurement framework for local e-government since research in this field is limited. This study adopted a positivist quantitative research and used triangulation web evaluation methods (heuristic evaluation, user testing, automatic link checkers, and Alexa) to test multiple-case study of Saudi city websites. The proposed E-City Usability Framework is unique in integrating 3-dimension measures (website usability, e-services, and the number and type of e-services), and in using multi-orientations to cover several aspects of e-government: output (information and services), outcomes (citizen-centricity indicators), model, and model-based assessments.Existing e-government models were criticized, and the findings employed in developing the proposed framework. The best web evaluation methods were heuristic evaluation and user testing, while link checkers and Alexa proved to be unreliable tools; nevertheless, they can be used as a useful complementary approach. Saudi city websites were ranked by website quality, e-services, and overall evaluation. Common usability problems in these websites were found to be: the sites were not citizen-centered, limited e-services and information, no e-transaction, no emergency alerts, no municipal budget, and no city council reports. They also suffered from broken links, an inactive city map, a poor eComplaint section, and a nonfunctioning search facility

Modelo multidimensional para avaliação da qualidade de websites de imobiliárias

Tese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia de Produção, Florianópolis, 2021.Manter um site atraente, apropriado ao público, fácil de usar e destacado no segmento em que atua é premissa para qualquer negócio que pretende usar a internet de maneira eficaz. No mercado imobiliário, onde a concorrência é acirrada e o uso da web é cada vez mais intenso, esses são fatores ainda mais relevantes. Neste contexto, considerando a chegada da transformação digital, a importância do setor imobiliário para a economia, a relevância que as imobiliárias possuem para as transações imobiliárias e o crescimento da busca de imóveis por meio dos websites, a construção de medidas de avaliação da qualidade dos websites das imobiliárias se torna indispensável. Entretanto, sabe-se que a elaboração de medidas da qualidade no contexto de websites é uma tarefa desafiadora, pois a qualidade em websites é um conceito complexo e de natureza multidimensional. Desse modo, o objetivo dessa pesquisa é mensurar a qualidade de websites de imobiliárias brasileiras. Para isso essa pesquisa está estruturada em quatro fases: (i) definição do construto qualidade de websites por meio de uma revisão sistemática da literatura; (ii) avaliação da satisfação dos usuários de websites de imobiliárias, podendo identificar itens que os usuários estão mais e menos satisfeitos; (iii) verificação da percepção dos gestores imobiliários sobre a importância de critérios no website imobiliários, levando em consideração o impacto da pandemia, observando se a percepção da importância de determinados itens modificou depois do início da pandemia; e (iv) construção de uma escala para avaliar os websites de imobiliárias brasileiras. Os resultados demonstraram que embora existam centenas de dimensões utilizadas para mensurar a qualidade de websites, estas possuem similaridades e podem ser agrupadas. Além disso, foi evidenciado a ausência de escalas para mensurar qualidade de websites no contexto imobiliário. Assim, apoiado pelos resultados obtidos com a avaliação da satisfação dos usuários e o da percepção dos gestores imobiliários, foi desenvolvido um instrumento composto de 71 itens e coletado dados de 679 websites de imobiliárias. Utilizando o meio modelo compensatório de dois parâmetros da Teoria da Resposta ao Item, uma escala tridimensional foi construída, contendo as dimensões: qualidade da informação, qualidade de serviço e qualidade de sistema. A pesquisa pioneira no tema de qualidade de websites de imobiliária contribui para a discussão acerca da temática, contribuindo para o avanço da discussão sobre a qualidade de websites. Futuramente a escala desenvolvida pode auxiliar as imobiliárias a melhorarem seus websites e até ser utilizado como um checklist para construção de websites de imobiliárias, verificando os itens que aumentam o grau de qualidade do website.Abstract: Keeping a website attractive, appropriate to the public, easy to use and highlighted in the segment in which it operates is a premise for any business that intends to use the internet effectively. In the real estate market, where competition is fierce and web usage is intense, these are even more relevant factors. In this context, considering the arrival of the digital transformation, the importance of the real estate sector for the economy, the relevance that real estate companies have for real estate transactions and the growth of the search for properties through websites, the development of measures to assess the quality of real estate websites becomes indispensable. However, it is known that quality measures in the context of websites is a challenging task, as the quality of websites is a complex and multidimensional concept. Along this lines, the objective of this research is to measure the quality of Brazilian real estate websites. For this, this research is structured in for steps: (i) definition of construct referent of websites quality through a systematic literature review; (ii) evaluation of user satisfaction of real estate websites, being able to identify items that users are more and less satisfied; (iii) verification of the perception of real estate managers about the importance of criteria on the real estate website, taking into account the impact of the pandemic, observing whether the perception of the importance of certain items changed after the beginning of the pandemic; e (iv) development of a scale to evaluate Brazilian real estate websites. The results showed that although there are hundreds of dimensions used to measure the quality of websites, they have similarities and can be grouped. Furthermore, the absence of scales to measure quality of websites in the real estate context was evidenced. Thus, supported by the results obtained from the assessment of user satisfaction and the perception of real estate managers, an instrument consisting of 71 items was developed and data was collected from 679 real estate websites. Using the two-parameter compensatory model of Item Response Theory, a three-dimensional scale was development, containing the dimensions: information quality, service quality and system quality. The pioneering research on the theme of quality of real estate websites contributes to the discussion on the subject, contributing to the advancement of the discussion on the quality of websites. In the future, the scale developed can help real estate companies to improve their websites and even be used as a checklist for real estate website development, checking the items that increase the quality of the website
