3. 3 © 2005-2006 The ATHENA Consortium. Interoperability difficulties are not purely technical problems. Lack of interoperability emerges from proprietary development, unavailability or oversupply of standards, and heterogeneous platforms. The situation became more critical through new business paradigms like extended enterprises and networked organisations that require businesses to work together to achieve further benefits. A holistic perspective on interoperability will be adopted to achieve real, meaningful interoperation between enterprises. Adoption of a holistic perspective on interoperability Interoperability Processing

4. 4 © 2005-2006 The ATHENA Consortium. The Interoperability framework is represented via three main layers: Business, Knowledge and ICT solutions. Finally, a “fourth dimension” has been introduced: the semantics that cut across the three layers.

5. 5 © 2005-2006 The ATHENA Consortium. The Business layer all issues related to the organisation and the operations of an enterprise are addressed. Interoperability at business level should be seen as the organisational and operational ability of an enterprise to cooperate with other, external organisations. In order to understand the business compatibility of two organisations, it is necessary first to understand each other. To this end, each organisation must achieve a deep understanding of itself. Business layer

6. 6 © 2005-2006 The ATHENA Consortium. The Knowledge layer deals with acquiring a deep and wide knowledge of the enterprise. Interoperability at knowledge level is the compatibility of the skills, competencies, and knowledge assets of an enterprise with those of other, external organisations. In collaborations, two organisations need to verify their compatibility at the knowledge level, by at the same time preserving their competitive advantage and confidentiality issues. Knowledge layer

7. 7 © 2005-2006 The ATHENA Consortium. The ICT Systems layer focuses on the ICT solutions that allow an enterprise to operate, make decisions, exchange information within and outside its boundaries, and so on. Interoperability at ICT Systems level is the ability of an enterprise’s ICT systems to cooperate with those of external organisations. ICT Systems layer

8. 8 © 2005-2006 The ATHENA Consortium. The semantic dimension cuts across the business, knowledge and ICT layers. To overcome the semantic barrier, which emerges from different interpretations of syntactic descriptions, precise, computer processable meaning must be associated with each concept. It has to be ensured that semantics are exchangeable and based on a common understanding. This can be achieved using an Ontology and an annotation formalism for meaning.

The objective of PPM is to allocate resources in a way to maximize sales and profits and minimize risks, as well as to achieve balance of development projects. The three main phases of the PPM process are: Selection and Analysis Phase Screening Phase Operational Feedback Phase PPM Scenario description

10. 10 © 2005-2006 The ATHENA Consortium. The analysis of the as-is situation of the PPM Scenario has revealed several problems: The communication among the different product portfolios is insufficient. Collaborative work needs to be supported by providing actors with the tools and communication support through a single point of entry (workplaces). Knowledge islands exist somewhere in the corporate environment. Knowledge sharing needs to be supported. Decision-making activities are poorly supported due to lack of information integration from various ICT systems. Cohesion of such decision-making activities with strategic plans and operational results needs to be supported. Objectives decomposition and their mapping to specific process roles and tangible benefits needs to be supported. As-is situation: Summary of problems
