Despite recent interest in the role of trust in Information Systems, the potential of IS to foster trust in business relationships remains largely untapped. In order to better realize this potential, this dissertation examines three areas of IS trust research for which research is particularly limited: (1) the IT artifact as a target of trust, (2) IS-based source credibility as an antecedent of trust, and (3) the effect of anonymity on trust in online environments. The objective of this dissertation is to examine the effects of IS on trust in each of these areas. To do so, a multi-paper dissertation format is adopted in which each area examined constitutes a distinct, though complimentary, study. Together, these studies further research on how IS can enhance trust in business relationships.

[pt] As rotinas organizacionais constituem um elemento central nas organizações; uma grande parte do trabalho é realizada por meio de rotinas (FELDMAN, 2000). As rotinas impactam na performance das organizações, e são uma importante fonte de mudança endógena (CACCIATORI, 2012). Uma série de artefatos podem ser associados às rotinas organizacionais. Muitos desses artefatos são denominados artefatos tecnológicos, e estão relacionados à tecnologia da informação, como os sistemas ERP s (Entreprise Resource Planning) (D ADDERIO, 2003). As rotinas organizacionais podem ser estudadas por meio de seus aspectos ostensivos (padrões abstratos), performativos (ações específicas) e artefatos (manifestações físicas das rotinas) (PENTLAND e FELDMAN, 2005). O papel da tecnologia também pode ser percebido na construção e no desenvolvimento das competências coletivas, por meio da aprendizagem e interações dentro das comunidades de prática (HSIAO et al., 2006), ou pela transferência das competências na gestão da mudança tecnológica (BARBAROUX e GODÉ, 2012). Retour e Krohmer (2006) oferecem uma proposta para o estudo das competências coletivas, por meio da articulação entre quatro atributos constituintes (referencial comum, linguagem compartilhada, memória coletiva e engajamento subjetivo). Outros trabalhos trazem a dentificação das competências coletivas por meio destes atributos (PAUVERS e BIENFAIT, 2011; COLIN e GRASSER, 2011), mas não se relacionam à ação direta ou indireta do componente tecnológico. Este estudo tem como objetivo investigar, a influência de um artefato tecnológico sobre as rotinas organizacionais e em decorrência, sobre os atributos das competências coletivas da organização. Com isso, tem-se a pergunta de investigação: como a inserção de um artefato tecnológico pode (re)configurar as rotinas organizacionais e por consequência impactar os atributos das competências coletivas em uma organização.? A proposta metodológica consiste em um estudo de caso (YIN, 2010), baseado em uma instituição pública federal de ensino. Trata-se de uma organização complexa, regulamentada, distribuída e com uma formação histórica heterogênea de suas unidades, e que passa por um momento único, com a implantação de um artefato tecnológico de grande porte (denominado Projeto Conecta), ocasionando mudanças em toda estrutura organizacional. A pesquisa foi realizada a partir de 25 entrevistas semiestruturadas, obtidas em cinco unidades da instituição, localizadas em quatro diferentes cidades em Minas Gerais no período de março a maio de 2016. A delimitação foi dada a partir de um projeto de implantação de um novo artefato tecnológico, abrangendo toda a instituição. Os dados foram analisados sob uma abordagem qualitativa, interpretativa, com a técnica de análise de conteúdo (BARDIN, 1977). Os resultados evidenciaram não somente uma modificação, mas também uma ressignificação das rotinas a partir da inserção do novo artefato tecnológico. Essa ressignificação das rotinas também trouxe impactos em níveis diferentes para cada atributo das competências coletivas, sugerindo também uma possível ressignificação destas competências. As relações entre os elementos analisados configuram um mapa conceitual, construído a partir das seguintes categorias gerais: descrição das rotinas do estudo, normatização das rotinas, artefato na ação das rotinas, reconfiguração das rotinas pelo artefato, ação das rotinas no referencial comum, ação das rotinas na linguagem compartilhada, ação das rotinas na memória coletiva, ação das rotinas no engajamento subjetivo. / [en] Organizational routines are a central element in organizations; a large part of the work is performed through routines (FELDMAN, 2000). Routines impact organizational performance, and are an important source of endogenous change (CACCIATORI, 2012). A number of artifacts can be associated with organizational routines. Many of these artifacts are referred to as technological artifacts, and are related to information technology, such as ERP systems (Entreprise Resource Planning) (D ADDERIO, 2003). Organizational routines can be studied through their ostensive (abstract), performative (specific actions) and artifacts (physical manifestations of routines) (PENTLAND and FELDMAN, 2005). The role of technology can also be perceived in the construction and development of collective competences, through learning and interactions within the communities of practice (HSIAO et al., 2006), or by transferring skills in the management of technological change (BARBAROUX and GODÉ, 2012). Retour and Krohmer (2005) offer a proposal for the study of collective competences, through the articulation between four constituent attributes (common referential, shared language, collective memory and subjective engagement). Other works bring the identification of collective competences through these attributes (PAUVERS and BIENFAIT, 2011; COLIN and GRASSER, 2011), but are not related to the direct or indirect action of the technological component. This study aims to investigate the influence of a technological artifact on organizational routines and, as a result, on the attributes of the collective competencies of the organization. Thus, the research question is: how can the insertion of a technological artifact (re) configure organizational routines and consequently impact the attributes of collective competencies in an organization.? The methodological proposal consists of a case study (YIN, 2010), based on a federal public institution of education. It is a complex organization, regulated, distributed and with a heterogeneous historical formation of its units, and that goes through a unique moment, with the implantation of a large technological artifact (named Projeto Conecta), causing changes in every organizational structure. The research was carried out from 25 semi-structured interviews, obtained in five units of the institution, located in four different cities in Minas Gerais from March to May 2016. The delimitation was given from a project of implantation of a new artifact The whole institution. Data were analyzed using a qualitative, interpretive approach using the content analysis technique (BARDIN, 1977). The results evidenced not only a modification, but also a re-signification of the routines from the insertion of the new technological artifact. This re-signification of routines also brought impacts at different levels for each attribute of collective competencies, also suggesting a possible re-signification of these competencies. The relationships between the analyzed elements constitute a conceptual map, constructed from the following general categories: description of the routines of the study, normalization of the routines, artifact in the action of the routines, reconfiguration of the routines by the artifact, action of the routines in the common reference, action of the routines in the shared language, action of the routines in the collective memory, action of the routines in the subjective engagement.

In the past years, the information was kept on the physical medium and people struggle more to get the right information. Everyone tries to search the information in a smart way using different scenarios. With the passage of time as computer became the essential part of daily life and the search engines came into action. When we talk about the search engines, they are also the part of Information Technology (IT) revolution to find the material or information in a simple and easy way in less time span. These search engine help in finding the information instead of the physical media quickly. By the never ending efforts of the researchers, the information which was available only in physical medium or from other resources has been transferred to a single platform using IT artifacts. Now, the efficient accessibility of this information is an issue. There are a number of e-services available on the computer network around the globe from where the users can get the information according to their needs, but some time these e-services do not provide user demanded results because of the improper implementation of IT artifacts.Our research is focused on the e-Me project i.e. a comprehensive knowledge based Electronic Assistant platform given by Innovation Lab. This project has a number of good e-services to assist the user electronically in course schedules, record of books, planning transportation, course program progress and number of other tasks at one place. This project is also used to co-design approach to initiate the users as a stakeholder. The users create a profile according to the services of the e-Me project and the users can search these services according to their needs. Our research is to provide an efficient smart filter to search information about services according to users needs. We studied the IT Artifacts and adopt the new research methodology called ―Action Design Research‖. This research is specifically adopted by researchers for the IT based system. In our research we cover the core IT Artifacts i.e. human computer interaction, user centered design, interaction design principles. These artifacts are further verified by the documents in the form of interviews and observation. The results were achieved by taken interviews from three interviewers having expertise in IT fields and they are also aware about the users‘ perception. At the end of this research we came up with the design prototype of the smart filter. / Program: Magisterutbildning i informatik
