Open innovation has become a fruitful approach to increasing the potential of innovation in organisations. Similar to traditional innovation, an open innovation approach can be characterised in three phases; namely idea generation, idea assessment and idea implementation/diffusion. While the academic community has begun to provide initial guidance...
Conference Paper
Situational method engineering is an approach to dynamically configure method fragments. In doing so, complete methods can be tailored to suit concrete project situations. Identifying such situations and selecting appropriate fragments is crucial for a successful method engineering process. In the field of service identification for service-oriente...

Modern enterprise knowledge management systems typically require distributed approaches and the integration of numerous heterogeneous sources of information. A powerful foundation for these tasks can be Topic Maps, which not only provide a semantic net-like knowledge representation means and the possibility to use ontologies for modelling knowledge...
Chapter
Although the industrialization of financial products and services has been on top of the agenda in the financial service domain for many years now, there is still considerable pressure to lower the cost income ratio. This continuing trend stimulates restructuring of the IT environments (ECB 2004) and thus leads to new types of risk. From the corpor...

While CORBA has been very successful in the domain of enterprise computing, its adoption for mobile devices is obstructed by a central problem: the limited resources of such devices. If standard-compliant CORBA-based applications are to be executed on mobile devices, storage requirements, for example, represent a major bottleneck. But for all that,...

Part of the number of Common Object Request Broker Architecture (CORBA) services specified by the Object Management Group is CORBA's Property Service (PS), which can be used to provide CORBA objects dynamically with additional properties not declared in their static Interface Description Language (IDL) type definitions. Although the management of d...
Conference Paper
The use of dynamic properties in CORBA applications is supported by CORBA 's Property Service. This service, however, does not support temporary properties with restricted lifetimes. In this paper, we describe an easy-to-use Enhanced Property Service (EPS) that provides the required additional functionality while being backwards compatible to the o...
