Employees increasingly use unauthorized technologies at the workplace, which is referred to as shadow IT. Previous research identifies that shadow IT is often collaborative systems used by employees to collaborate, communicate, and share content with coworkers, clients, or external partners. Based on these previous findings, we propose that shadow IT usage may positively influence organizational knowledge sharing (KS), which is central to knowledge management practices. Thus, this research aims to (1) identify the types and occurrences of shadow IT used by employee in the workplace, (2) investigate how KS (donation and collection) occurs via shadow IT, and (3) investigate how shadow IT influences KS. This is an exploratory study based on a qualitative approach. We performed interviews with IT users to answer the research question. Our findings identify that most of the interviewees use collaborative systems and mobile devices unauthorized by the IT department to share knowledge and communicate with their coworkers. The most common IT cited are WhatsApp and Skype, as well as solutions to store and share content, like Google Drive. In addition, several employees reported using shadow IT mainly because organizations do not provide suitable tools to communicate efficiently. We conclude that shadow IT can facilitate KS, primarily when people are geographically distributed since these unauthorized systems provide real-time communication. Our theoretical contribution is to expand current knowledge about shadow IT and reinforce the importance and prevalence of informal and decentralized KS within organizations. As for the practical implications, our article can help IT managers to better understand the usage of shadow IT and how they can balance the risk and benefits of this phenomenon.

Purpose-The purpose of this paper is to provide an analysis of the studies about workaround behavior in the Information Systems (IS) area, addressing its positive and negative aspects and raising the key related issues. Design/methodology/approach-A systematic literature review was conducted to verify how workaround behavior has been approached in IS studies. A qualitative method was adopted and implemented in two stages: selection of articles from the time period 2007-2017 in the databases Web of Science, ScienceDirect and Scopus and analysis of the selected articles. Findings-The results showed that many studies have been concerned with identifying the principal reasons for the manifestation of workaround behavior and the measures taken to reduce its impacts. Many studies from international journals examined the implementation of an ERP along with the workaround behavior. The need to expand the national studies on workaround behavior is emphasized, because the majority of the identified studies are international. Research limitations/implications-The key limitation is related to the period of analysis, because only articles published since 2007 were selected. Practical implications-This paper contributes to both theory and practice, bringing relevant concepts about workaround behavior, and corroborating the importance of the studies on workaround in the IS area. The literature review of the 20 articles analyzed reveals the main features in each article, such as theoretical and methodological aspects that support the research. Based on this analysis, a conceptual map was developed presenting the most relevant points about workaround behavior, where the causes, the negative and positive consequences, the types of solutions and the organizational and individual impacts are presented. Originality/value-Research into workaround behavior has increased in recent years, however very few studies have been conducted in Brazil. To the best of the authors' knowledge, no articles regarding Brazil and this subject were published between 2007 and 2017. Thus, this paper seeks to redress this imbalance.

As empresas estão investindo em Tecnologia da Informação (TI) e aproveitando, ao máximo, as vantagens que ela proporciona, para mudar os processos de negócio e melhorar o desempenho das operações. Dentro deste contexto, pretende-se investigar, aqui, o uso de um Sistema de Gestão de Transporte (TMS). O objetivo geral deste estudo é avaliar o impacto do uso do TMS e sua relação com o desempenho das operações de transporte das empresas e com os prestadores de serviços de transporte na percepção dos usuários. O método utilizado foi a pesquisa survey e um modelo conceitual foi elaborado e validado utilizando modelagem de equações estruturais (PLS-SEM). O resultado indica que os benefícios de um TMS têm impacto positivo no desempenho das operações de transporte, que, por sua vez, têm impacto positivo na relação com fornecedores de serviço de transporte.
