Ontological representation and governance of business semantics in compliant service networks

The Internet would enable new ways for service innovation and trading, as well as for analysing the resulting value networks, with an unprecedented level of scale and dynamics. Yet most related economic activities remain of a largely brittle and manual nature. Service-oriented business implementations focus on operational aspects at the cost of value creation aspects such as quality and regulatory compliance. Indeed they enforce how to carry out a certain business in a prefixed non-adaptive manner rather than capturing the semantics of a business domain in a way that would enable service systems to adapt their role in changing value propositions. In this paper we set requirements for SDL-compliant business service semantics, and propose a method for their ontological representation and governance. We demonstrate an implementation of our approach in the context of service-oriented Information Governance

Simulating awareness in global software engineering: a comparative analysis of Scrum and Agile Service Networks

Abstract—Global software engineering (GSE) is a business strategy to realize a business idea (i.e. the development project) faster, through round-the-clock productivity. However, GSE creates a volatile and unstable process in which many actors interact together against unpredictable premises (e.g. cultural or time differences), often producing unexpected outcomes (e.g. compacting effects of distance and time). So far, Scrum has been used extensively for embarking in global software engineering, but many of the problems in Scrum-based GSE could still benefit from the usage of ad-hoc supporting tools (e.g. information continuity between timezones, cultural differences, developers awareness, etc.). Agile Service Networks (ASNs) are networks of service oriented applications (nodes) that collaborate adaptively towards a common goal. ASNs offer a way to represent GSE professionals through service-oriented “social” nodes in a “small-world” network (much like a Facebook for a specific GSE project). This paper presents a comparison between the two approaches, namely Scrum and ASNs, to determine ASN’s potentials as mechanisms to maintain awareness in GSE

Value-based service bundling: a customer-supplier approach

Due to future ubiquitous service environments, approaches for dynamic delivery of services face new challenges. Since the web 2.0 gave to customers the change to interact with the Internet, they are not any more static entities but can also contribute to the design or co-creation of new services. In this paper we show how customers can help to dynamically bundle services; our approach is based on customer and supplier perspectives. A broker is in charge of matching both perspectives, depicting not only customer desires but also supplier offerings. Moreover, our approach is illustrated by a case study. Finally, we provide some reflections as well as future lines of research. © 2011 IEEE
