In the last 10 years several approaches and technologies other than MAS (such as Web services and Grid computing) have emerged, with the support of the industry, providing their own solutions to distributed computation. As both Web services and Grid computing are based in the concept of service orientation, where all computation is split in independent, decoupled services, there is an opportuni...

An applied research for the incremental evolution of a service oriented architecture for local eGovernment portals has been developed. Our reference eGovernment environment, currently adopted by a hundred local public administrations in Veneto region, is a dual model with a G2C interface towards citizens and a complementary G2G interface for municipal government staff, both interconnected and s...

Enterprise Services have been proposed as a more business-friendly form of web services which can help organizations bridge the gap between the IT capabilities and business benefits of Service Oriented Architecture. However up until now there are almost no methodologies for creating enterprise services, and no lists of definite criteria which constitute a “good” enterprise service. In this pape...

IT governance and management in an enterprise plays an important part in generating value for the stakeholders [1]. COBIT 5 is a framework for the governance and management of IT enterprises. In 2012 the latest version of this framework was released introducing important features. One of those features is the evolution from COBIT 4.1 Maturity Model to COBIT 5 Process Capability Model. This pape...

The symbiosis between an enterprise architecture and service-oriented architecture results in so-called service-oriented enterprise architecture and brings up new problems for serviceoriented enterprise systems engineering. One of the most important is a business service quality definition, specification and evaluation. The paper proposes a formal model of enterprise business service quality ev...

This paper investigates the coexistence of and complementary use of COBIT and ISO 17799 as reference frameworks for Information Security governance. The investigation is based on a mapping between COBIT and ISO 17799 which became available in 2004, and provides a level of 'synchronization' between these two frameworks.

The assessment of Enterprise Governance of IT (EGIT) mechanisms, such as COBIT and ITIL, is considered highly complex and implies a duplication of resources. The main goal of this research is to reduce the complexity of EGIT mechanisms by facilitating the assessment of these mechanisms when used simultaneously. Organisational stakeholders should be able to easily understand the impact of implem...

Enterprise governance of IT (EGIT) is about the definition and implementation of processes, structures and relational mechanisms that enable both business and IT people to execute their responsibilities in support of business/IT alignment and the creation of business value from IT-enabled business investments. In this field, practice-oriented guidance like COBIT and Val IT are often promoted as...

The Service-oriented Architecture paradigm has become a widely adopted solution for enterprise application landscapes. SOA promises system integration improvement, business and IT alignment, applications reusability, and fast adaptability to changing requirements. Yet, the advantages that SOA offers lead to its main management challenges. An SOA consists not only of services. Business requireme...

As information technology (IT) persists as an integral means for achieving success in organisational business processes, IT Governance (ITG) continues to be a top priority too. Current reports show that enterprises continue to suffer financial losses as a result of poor ITG practices. To better govern IT resources, many have tried to address this problem by migrating to the highly recommended I...
