SUMMARY
Digitization and the related datacation produce huge amounts of data. Organizations have started to exploit these
new data in order to gain benets. Exploring this big data jungleis a new area for both scholars and practitioners,
and the experiences of early adopters are valuable. This paper analyses big data use cases described in the academic
literature by using computerized content analysis methods. Based on the analysis results, we have conceptualized
themes and guidelines of big data in the context of an organization, thus contributing to the emerging research of
big data. In addition to the realized benets, the case studies reveal issues regarding technology, skills, organiza-
tional culture and decision-making processes. The paper also points out several new research avenues,acts as a ref-
erence collection to big data case studies found in academic sources, and bridges theory and practice by pointing
out several topics that practitioners should consider. Copyright © 2016 John Wiley & Sons, Ltd.
1. INTRODUCTION
Today, new digital technologies produce vast amounts of various types of data (Gantz & Reinsel, 2011), often
referred to as big data. From the point of view of technology, big data are different from traditional transaction
data, requiring new data management and analysis technologies (Laney, 2001). More importantly, several
sources, including Davenport (2014); Manyika et al. (2011) and Mayer-Schönberger and Cukier (2013),
claim that big data have potentially huge effects on many industries. Technology and data drives change,
and as Dehning, Richardson, and Zmud (2003) and Sainio (2005), for example, suggest, companies must
link their strategy with technology.The business environment is changing. However, it is difcult to forecast
the impacts at the micro level, as digitization and data deluge are a new, emerging phenomenon.
The effects of this phenomenon are different for each company. As an example, self-driving cars,

which will invade the markets in the future, will have signicant effects on various rms, like car dealers
and insurance companies. However,the potential and the challenges that a car dealer faces will differ sig-
nicantly from those of an insurance company.Realizing the potential implies that this new, data-driven
paradigm will affect companiesstrategies and business models heavily. Several excellent pieces of work
exist on business transformation. Venkatraman (1994) builds a framework that helps understand the ef-
fects of the transformation. Christensen (2013) explains clearly how incumbent companies fail con-
stantly in utilizing new, disruptive technologies. Sainio (2005) shows that companies are often well
aware of new, emerging technologies, but neglect linking the technologies with their strategies.
There are some trailblazers, Google and Amazon being the most obvious examples, which have built
their business models around data. These kinds of examples, as well as some previous studies (e.g. Porter

& Millar, 1985; Dehning et al., 2003; McAfee & Brynjolfsson, 2012) indicate that companies utilizing
data heavily gain a competitive advantageover their less data-driven rivals. However,the data-driven ap-
proach is still a new paradigm for most organizations (Shen & Varvel, 2013). In addition, established
companies have their own history, processe sand capabilities. They just cannot turn their existing struc-
tures and business models upside down at once. The transformation takes time. When established rms
start to explore the possibilities of big data, they can learn from the experiences and methods of the early
adopters. Several studies (e.g. De Mauro, Greco, & Grimaldi, 2015; Wamba et al., 2015) recognize the
need for guidelines and a conceptual framework for big data. Oneway towards this goal is to examine the
experiences of real big data projects. In this ar ticle weuse computerized text analysis methods to analyse
a number of big data case studies documented in academic publications.
The key contribution of this article is that we synthesize the ndings (benets and challenges) of our case
study analysis to a set of generic themes and guidelines. This contributes to the research on big data by
conceptualizing existing practices and pointing out several new research avenues. In addition, this work
bridges practice and theory, acts as a reference collection to currently known, peer-reviewed big data case
studies, and benets practitioners by providing guidelines and experiences from the earlyadopters of big data.
2. BIG DATA CASE STUDIES
This section describes the research process we used to identify big data case studies. We used the systematic
mapping study approach presented by Kitchenham (2007). Our goal was to identify well-documented big
data case studies in the academic literature. Well-documented in this context means a peer-reviewed, high
quality source. In order to cover the area broadly, we performed a systematic mapping study. According to
Kitchenham (2007), mapping studies are designed to give a broad overviewof a research area. Mapping stud-
ies typically have broad research questions. Our target (research question) was simple: to locate as manybig
data case studies documented in peer-reviewedsources as possible, and to capture the common concepts and
lessons learned in these use cases. Figure 1 gives an overviewof the search process.
2.1. Search Strategy
Big data is a multidisciplinary phenomenon. Unlike some other subject areas, big-data-related articles
cannot be found only in certain highly focused forums. Although there are some new journals that
