The relationship among development skills, design quality, and centrality in open source projects

The paradigm of the Internet of Services envisions trade on a global service-enabled internet. Companies, which participate in this new world of services, face the challenges of changing market conditions, new competitive threats, and new legal regulations. Service-oriented Architectures (SOA) provide a promising way to address some of these challenges at the level of the company’s IT infrastructure. In order to guideline an enterprise’s organization and IT and ensure smooth operations, governance frameworks have been established. More specifically, IT Governance and recently SOA Governance have been introduced. The basic structure of IT Governance frameworks is applicable to an SOA. However, they lack functionality or applicability concerning SOA-specific challenges. Current approaches, which focus on mere SOA Governance, lack framework scope and are mostly driven by individual companies. This issue aggravates taking into account the shift to an Internet of Services. We identify key issues and provide initial insights on building blocks for a Service Governance Framework which enables operations for companies in a moderated service network. We discuss service life cycle phases, stakeholder roles, and management processes taking into consideration existing frameworks such as ITIL and CObIT as well as industry-specific approaches from companies such as SAP, Oracle, and HP

Towards a Consistent Service Lifecycle Model in Service Governance

Introducing an SOA in a company brings new challenges for the existing management. Small loosely coupled services allow the Enterprise Architecture to flexibly adapt to existing business processes that themselves depend on changing market environments. SOA, however, introduces a new implicit system complexity. Service Governance approaches address this issue by introducing management processes and techniques, and best practices to cope with the new heterogeneity. Service lifecycle management is one aspect. Existing definitions of service lifecycles vary greatly.. In this paper, we compare existing service lifecycle approaches concerning defined phases and process. In particular, we challenge the purpose of the distinctions made between design time, runtime, and change time. Concluding, we propose a consolidated service lifecycle model for usage in Service Governance
