Workshop on Service oriented Enterprise Architecture for Enterprise Engineering

Helsinki,Finland

There are different paradigms for creating enterprise architecture. The most important regarding the purpose of this workshop is to encapsulate the functionalities provided by IT resources as services. By this means, it is possible to clearly describe the contributions of IT resources both in terms of functionality and quality and to define a service-oriented enterprise architecture. Service-oriented enterprise architecture easily integrates wide-spread technological approaches such as SOA or emerging ones as the cloud computing because they also use service as structuring paradigm. Service-oriented enterprise engineering further develops the enterprise engineering approach selecting service as governing paradigm. The enterprise goals and strategies are mapped to a service-oriented enterprise architecture.

Service-oriented enterprise architecture differentiates four layers of services. Thus, its scope is much broader than the scope of the service-oriented architecture (SOA) and also includes services not accessible through software such as business and infrastructure services. Services of different layers may be interconnected in service (value) nets to provide higher level services.

1. Business services are services, which directly support business processes. Business processes can also be developed dynamically (on-the-fly) using business services which are available in a repository for a given business domain. An example is call-centre services provided by an external service provider.

2. Software services exist as two types: (i) human-oriented applications, which are provided as Software as a Service, (ii) application services which are part of so-called Service-Oriented-Architectures that are a popular paradigm for creating enterprise software .

3. Platform Services provide support of the development of applications. They provide services for the execution of applications, middleware stacks, web servers etc.

4. Infrastructure services are more hardware-flavoured services, which are provided using computers. They may have a human addressee but contain many infrastructure services such as providing computing power, storage etc. They are an important topic in management and practice collections such as ITILV3 or standards such as ISO/IEC 20000 have gained a high popularity.

The goal of the workshop is to develop concepts and methods to assist the engineering and the management of service-oriented enterprise architectures and the software systems supporting them. Especially three themes of research shall be pursued:

1. Alignment of the enterprise goals and strategies with the service-oriented enterprise architecture
2. Design of the service-oriented enterprise architecture
3. Mapping of service-oriented enterprise architecture to enterprise resources

During the workshop we will discuss the following topics:

1. Alignment of the enterprise goals and strategy with the service-oriented enterprise architecture
- Which interdependencies exist between services and business strategy?
- Which concepts and methods are necessary to align services with the business strategy?
- Which new potentials to reengineer business processes are created by services?
- How are non-functional requirements derived from enterprise goals and strategy?
- How are services aligned with non-functional requirements?
- How are services aligned with compliance requirements?
- Are the compliance and governance requirements enforced using service-oriented enterprise architectures?

2. Design of service-oriented enterprise architecture
- How are business, software, platform and infrastructure services defined?
- How are business services assigned to business processes?
- How are business services assigned to non-functional requirements?
- How are service (value) nets -consisting of business, software, platform and infrastructure services- created?
- How does service-oriented enterprise architecture, interrelate with cloud computing?
- How do meta-services differentiate for business, software, platform and infrastructure services?
- How are appropriate meta-services designed?
- Which phases do the lifecycle of business, software, platform and infrastructure services contain?
- How can the fulfilment of non-functional requirements be monitored?
- Which benchmarks and key performance indicators should be applied to services?
- Which approaches exist for the continual improvement of services?

3. Mapping of service-oriented enterprise architecture to enterprise resources
- Which resources are relevant for Service-oriented Enterprise Architecture?
- How are services mapped to enterprise resources?
- Which approaches exist to map services to resources?
- Which information system architectures are adequate for services?
- How can non-functional requirements be mapped to capacity planning of resources?
