Deducing Service Ownerships in Financial Networks

Service-oriented architecture (SOA) is recognized as an enabler to overcome limitations of traditional monolithic application architectures such as efficiently adapting to changing business requirements and external partners with individual systems. However, services within any SOA require broadly accepted service definitions and a systematic management after the design stage. Thus, ownership of these services among the business partners as well as within the enterprise is essential for the implementation, operation and management of SOA and ultimately its business value. This paper enhances existing approaches which mainly comprise roles and management activities on a generic level. It proposes a procedure for identification and allocation of service ownerships from a business perspective which has been applied in the banking industry

A Framework for the Design of Service Maps

The concept of service-oriented architecture (SOA) is recognized as an important enabler for business transformation and application integration. Service maps emerge when individual services are (pre)configured on various architectural levels. For example, business-oriented service maps sustain the communication and coordination among participants within and between businesses. Difficulties occur when, based on different service design strategies, heterogeneous service maps are created which need to be aligned. A methodological approach to establish a systematic design process for such service maps within companies or business networks is needed

The Impact of Service-Oriented Architecture on Business Networkability

Increased networking among firms has become a competitive necessity in many industries and the ability to efficiently establish, operate and dissolve business relationships has become a competitive advantage. The degree of this networkability is influenced by several factors, such as organizational structure, business processes, people and culture, but also information systems. In fact, current technological developments aim at the efficient and flexible orchestration of standardized modules, referred to as services. Past research has analyzed networkability primarily qualitatively without providing a specific perspective on the concept of service-oriented architecture (SOA) which has only emerged on a broad scale since the beginning of this century. This paper is a first attempt to investigate the impact of SOA on the notion of business networkability. It is assumed that the ability to flexibly link business services among business partners also positively influences the firm’s networkability. Empirical evidence will be provided from the financial industry which is currently undergoing a strong vertical disintegration. The results show a moderate, but nevertheless significant impact
