physical presence, while others have completely
transferred their activities to the web.
Nevertheless, we are witnessing today yet another
transformation of commerce. The advent of mobile
technologies, supported by the great availability of
wireless networks and easy to use handled devices
has given way for the rise of mobile commerce (m-
commerce). This type of activity is basically “an
important step towards achieving an anywhere,
anytime paradigm” since it is possible to buy and sell
products and services at all times from all locations,
i.e., these two dimensions no longer constrain
business activities (Maamar, 2003).
Junglas and Watson argue that these two
paradigms, e-commerce and m-commerce, exhibit
some features, which differentiate them entirely from
one another. Specifically, the authors argue that m-
commerce and e-commerce exhibits significant
differences along the concepts of reachability,
accessibility, localization and portability (Junglas and
Watson, 2003). Indeed, while it may be said that both
paradigms provide to a certain extent all of the above,
the former, i.e., m-commerce, subject to other
variables (e.g., network availability) manages to
provide them in an unrestricted fashion, without
setting limits to e.g., reachability and portability.
Following m-commerce, it is posited that yet
another paradigm is about to emerge, that of ultimate
commerce (u-commerce) (Junglas and Watson,
2003). Weiser has introduced ubiquitous information
systems in his seminal paper (Weiser, 1991). In it, he
described a world where the boundaries between
everyday life and technology blur together as
information systems weave themselves into our
everyday activities. Based on this, Watson et al. have
defined u-commerce as “the use of ubiquitous
networks to support personalized and uninterrupted
communications and transactions between a firm and
its various stakeholders to provide a level of value
over, above, and beyond traditional commerce”
(Watson et al., 2002). In other words, u-commerce,
supported by ubiquitous networks and universal
devices, will help commerce become independent
from space and time, and extend itself beyond the
traditional paradigms (Junglas and Watson, 2003).
At the same time, beyond the transformations that
commerce has been undergoing recently, businesses
are yet again faced with more changes. It has been
noted that the structure of a typical business has been
changing recently as well, and that the typical
hierarchical structure has slowly but steadily shifted
into a pancake design. These two examples, the
pyramid and the pancake, occupy the two opposing
extremes of a spectrum (Schneckenberg, 2009), while
in between them there are several variations and
combinations of the two. To elaborate further, the
traditional pyramid reflects the “hierarchical culture,
in which leadership makes centralized decisions at the
top of the organization and pushes these decisions
vertically down to lower-level employees for
execution” (Schneckenberg, 2009). In contrast, the
pancake design places all employees on the same
level, as they are rather autonomous and make their
own decisions, drawing from their experience and
expertise. In these cases, the employees do not
necessarily need the authorization of central
management, but they can rely on their own
judgment.
These changes have been facilitated by two
different features. First of all, studies reveal that
currently there is a shift of demand from goods to
services. Therefore, contemporary businesses are in
need to deliver a service even in cases where they are
in fact produce a specific product (Greefhorst and
Proper, 2011). Secondly, recent advances have
allowed the decrease of costs for information and
communication technologies within a given
enterprise and there are those who posit that this is in
fact the primary reason for the organisational
transformation we witness today (Schneckenberg,
2009, Malone, 2004). What is important however, is
that this organizational transformation, from the
pyramid to the pancake, has led to the introduction of
decentralization of decision-making in modern
business; (Schneckenberg, 2009).
Lately, the trend towards lean and open to
innovation models of operation is increasing; Google
allows their employees to spend a significant percent
of their time in projects they initiate and conceive,
whereas GitHub, the developers’ online community,
has adopted the “open allocation” mode of operation.
The latter is the model of operation which enables
employees self-organize and deal with the problems
they think as important, without top management
guidelines or formal business structures at all. GitHub
team members, inspired by a common vision and
maintaining an advanced level of communication and
collaboration, have proved that this decentralized
approach is workable; it counts at least one effective
application, as GitHub ranks as a very popular tool
and repository for developers nowadays.
In the following paragraphs, the blockchain
technology is defined and briefly explained, including
insights to its main characteristics.
