3 THEORETICAL FOUNDATIONS OF SOA GOVERNANCE
3.1 The definition of SOA governance
Governance means defining, implementing, and monitoring rules, principles, standards,
procedures, and processes that allow organisations to manage their business by assigning
appropriate roles to employees (Torry, H.). It is also the establishment of responsibility,
decision-making rights, as well as communication and escalation channels (Torry, H.). SOA
Governance is an extension of IT Governance and EA Governance (EA – Enterprise Architecture). Figure no. 2 presents these relationships.
The acronym SOA stands for Service Oriented Architecture. SOA defines the possibilities
of integrating applications and business processes through related services often referred to
as Web Services. The SOA architecture allows one to think in a natural way about the services that exist in the organisation and its environment. Depending on the role of SOA in the
organisation and context (related to business, architecture, implementation, or operation),
the following definitions can be distinguished:
• from a business perspective, SOA defines a set of business services that can comprise other
services, providing a certain value that an organisation wants to pass on internally or externally to its clients or partners,
• from an architectural perspective, SOA is an architectural style that supports service
orientation,
• from an implementation perspective, SOA defines infrastructure standards as well as the
programming and technology models used to implement services,
• from the usage (application) perspective, SOA contains a set of relationships and arrangements between service consumers and their providers, which determine the quality of service (Keen, M. & Adamski, D. & Basu, I. & Chilcott, P. & Eames, M. & Endrei, M. &
Fagalde, B. & Raszka, R. & Seabury. S.D. 2007).
3.2 Expected benefits of SOA Governance implementation
SOA Governance implementation is a difficult process that requires appropriate preparation both business-wise and from the IT department. For implementation to be successful,
the focus must be on four areas. The 4P principle, well known from the ITIL (Information
