examining agility in software Development Practice Sergio de Cesare, Mark Lycett, Robert D. Macredie, Chaitali Patel, and Ray Paul Agility is a facet of software development attracting increasing interest. The authors investigate the value of agility in practice and its effects on traditional plan-based approaches. Data collected from senior development/project managers in 62 organizations is used to investigate perceptions related to agile development. Specifically, the perceptions tested relate to the belief in agile values and principles, and the value of agile principles within current development/organization practice. These perceptions are examined in the context of current practice in order to test perceptions against behavior and understand the valued aspects of agile practice implicit in development today. The broad outcome indicates an interesting marriage between agile and plan-based approaches. This marriage seeks to allow flexibility of method while retaining control.

 

Barriers to systematic model
transformation testing

Model Driven Engineering (MDE)
techniques support extensive use of
models in order to manage the increasing
complexity of software systems.
Automatic model transformations
play a critical role in MDE since they
automate complex, tedious, error-prone,
and recurrent software development
tasks. For example, Airbus uses automatic
code synthesis from SCADE models
to generate the code for embedded
controllers in the Airbus A380.
Model transformations that automate
critical software development tasks
must be validated. The authors identify
characteristics of model transformation
approaches that contribute to the
difficulty of systematically testing
transformations as well as present
promising solutions and propose
possible ways to overcome these barriers.

factors that influence software Piracy: a View from Germany Alexander Nill, John Schibrowsky, James W. Peltier, and Irvin L. Young Software piracy has wide-ranging negative economic consequences for manufacturers and distributors striving to compete in a competitive global market. Indeed, software piracy is jeopardizing the future growth and development of the IT industry, which in turn disproportionately impacts countries with the highest piracy rates. This article details an exploratory study that investigated the relationship between a comprehensive set of factors and software piracy in Germany. The authors gleaned some valuable security measures from the results of the study that can be used as a starting point for industry and governments to develop programs to deter piracy.

 

the Requisite Variety of skills for it Professionals Kevin P. Gallagher, Kate M. Kaiser, Judith C. Simon, Cynthia M. Beath, and Tim Goles IT professionals today are beset by ongoing changes in technology and business practices. To thrive in such a dynamic environment requires competency in a broad range of skills, both technical and nontechnical. The authors contend the Law of Requisite Variety—adapting to change requires a varied enough solution set to match the complexity of the environment— can help explain the need for greater and broader skills among I T professionals. The article outlines a framework containing six skill categories critically important for the career development of IT professionals.

 

Panopticon Revisited Jan Kietzmann and Ian Angell Many claims have been made regarding the safety benefits of computer-supported surveillance technologies. However, like many technologies the advantageous door swings both ways. The authors compare how current computer and communication technologies are shaping today’s “panopticons,” pulling heavily from the 1787 prison architectural design by social theorist Jeremy Bentham that allowed prison officials and observers to keep an eye on prisoners without the imprisoned able to tell they are being watched.

the social influence model of technology adoption Sandra A. Vannoy and Prashant Palvia While social computing has fast become an industry buzzword encompassing networking, human innovation, and communications technologies, few studies have investigated technology adoption targeting the individual at the level of society, community, or lifestyle experience. The authors address this gap by developing social constructs and providing a theoretically grounded model for technology adoption in the context of social computing. Their model suggests that social computing action, cooperation, consensus, and authority are antecedents to social influence. And social influence, they contend, leads to technology adoption.

 

i, myself and e-myself
Cheul Rhee, G. Lawrence Sanders,
and Natalie C. Simpson
The human ego, developed from birth, is
central to one’s conscious self, according
to experts. This article examines the
concept of the virtual ego (one that
begins with the creation of an online
identity and functions only online)
and the notion of an online persona
as overarching concepts providing a
new rationale for understanding and
explaining online behavior. The authors
posit that an Internet user’s virtual ego
is distinguishable from his or her real
ego and argue that understanding the
differences between the two is essential
for advancing the dynamics of Web-based
social networks.

Beyond connection: situated
Wireless communities
Jun Sun and Marshall Scott Poole
Compared to traditional Internet-based
virtual communities, situated wireless
communities (SWCs) go beyond just
connecting people together. In fact, SWCs
enable people to share their common
physical and/or social context with each
other. With the availability of these cues,
the social interaction among members
within a community is significantly
enhanced. The authors detail four general
types of SWCs as well as give examples of
the strengths and weaknesses of each.
