O estudo parte do pressuposto teórico da Visão Baseada em Recursos (VBR) de que empresas que possuem recursos de Tecnologia da Informação (TI) tal como Big Data e fazem sua aplicação tendem a criar valor ao negócio e conseguem obter maiores suas taxas de retorno sobre o investimento (ROI). Neste contexto, o objetivo do estudo é identificar o uso de big data pelas empresas listadas no setor de consumo não cíclico da B3 (Brasil-Bolsa-Balcão). Para tanto, foram analisadas 25 empresas que compõem esse setor. A pesquisa classifica-se como quali-quanti e caracteriza-se como exploratória e descritiva. Os dados da pesquisa foram coletados através de relatórios de apresentação institucional, de sustentabilidade, relatórios integrados, trimestrais e anuais. Para categorizar os dados da pesquisa segundo os construtos aplicações, dados, analíticos e impactos, utilizou-se o formulário adaptado de Chen, Chain e Storey (2012) e o  tratamento dos dados se deu por meio da análise descritiva que explorou a descrição dos construtos do formulário na amostra pesquisada e a análise inferencial a partir do teste não paramétrico U de Mann-Whitney. Os achados apontam parcialmente que a adoção de capacidade ou recursos pode criar valor às empresas, nesse sentido. Esses resultados corroboram com os achados de Krishnamoorthi e Mathew (2018), de que os recursos tecnológicos de big data podem contribuir para gerar informações que adicionam valor à empresa, ou seja, que melhoram a rentabilidade dos investimentos.  Essa evidência é suportada também pelo estudo de Bharadwaj (2000), em que, foi descoberto que as empresas com alta capacidade de TI tendem a superar uma amostra de empresas de controle em uma variedade de lucro e medidas de desempenho baseados nos custos, o que é determinante para a maximização da margem de lucro da empresa e assim a rentabilidade dos investimentos.

Big Data & Analytics (BDA) ist zu einer kaum hinterfragten Institution für Effizienz und Wettbewerbsvorteil von Unternehmen geworden. Zu viele prominente Beispiele, wie der Erfolg von Google oder Amazon, scheinen die Bedeutung zu bestätigen, die Daten und Algorithmen zur Erlangung von langfristigen Wettbewerbsvorteilen zukommt. Sowohl die Praxis als auch die Wissenschaft scheinen geradezu euphorisch auf den „Datenzug“ aufzuspringen. Wenn Risiken thematisiert werden, dann handelt es sich meist um ethische Fragen. Dabei wird häufig übersehen, dass die diskutierten Vorteile sich primär aus einer operativen Effizienzperspektive ergeben. Strategische Wirkungen werden allenfalls in Bezug auf Geschäftsmodellinnovationen diskutiert, deren tatsächlicher Innovationsgrad noch zu beurteilen ist. Im Folgenden soll gezeigt werden, dass durch BDA zwar Wettbewerbsvorteile erzeugt werden können, dass aber hiermit auch große strategische Risiken verbunden sind, die derzeit kaum beachtet werden.

BACKGROUND This paper presents a systematic literature review of existing remote health monitoring systems with special reference to neonatal intensive care (NICU). Articles on NICU clinical decision support systems (CDSSs) which used cloud computing and big data analytics were surveyed. OBJECTIVE The aim of this study is to review technologies used to provide NICU CDSS. The literature review highlights the gaps within frameworks providing HAaaS paradigm for big data analytics METHODS Literature searches were performed in Google Scholar, IEEE Digital Library, JMIR Medical Informatics, JMIR Human Factors and JMIR mHealth and only English articles published on and after 2015 were included. The overall search strategy was to retrieve articles that included terms that were related to “health analytics” and “as a service” or “internet of things” / ”IoT” and “neonatal intensive care unit” / ”NICU”. Title and abstracts were reviewed to assess relevance. RESULTS In total, 17 full papers met all criteria and were selected for full review. Results showed that in most cases bedside medical devices like pulse oximeters have been used as the sensor device. Results revealed a great diversity in data acquisition techniques used however in most cases the same physiological data (heart rate, respiratory rate, blood pressure, blood oxygen saturation) was acquired. Results obtained have shown that in most cases data analytics involved data mining classification techniques, fuzzy logic-NICU decision support systems (DSS) etc where as big data analytics involving Artemis cloud data analysis have used CRISP-TDM and STDM temporal data mining technique to support clinical research studies. In most scenarios both real-time and retrospective analytics have been performed. Results reveal that most of the research study has been performed within small and medium sized urban hospitals so there is wide scope for research within rural and remote hospitals with NICU set ups. Results have shown creating a HAaaS approach where data acquisition and data analytics are not tightly coupled remains an open research area. Reviewed articles have described architecture and base technologies for neonatal health monitoring with an IoT approach. CONCLUSIONS The current work supports implementation of the expanded Artemis cloud as a commercial offering to healthcare facilities in Canada and worldwide to provide cloud computing services to critical care. However, no work till date has been completed for low resource setting environment within healthcare facilities in India which results in scope for research. It is observed that all the big data analytics frameworks which have been reviewed in this study have tight coupling of components within the framework, so there is a need for a framework with functional decoupling of components.
