DEMO, Co-creation Co-production, DEMO enterprise ontology (DEO), reciprocal transactions

Reciprocal transactions, in general, denote two groups of transactions, in which performing one group of transactions is in consideration of performing the other group of transactions. Seemingly simple situation is more complex because it covers reciprocal commitments and reciprocal fulfilment and can be also accompanied by quarrels and disputes between partaking parties during fulfilment of reciprocal transactions. The objective of the paper is to find and apply better methodology and its model that would provide better mechanism for handling reciprocal transactions and in this way better economic information systems. The DEMO Co-creation Co- production (CC-CP) model, which has its foundation in DEMO (Design Engineering Methodology for Organization) methodology is presented and applied on a simple example of a pizza shop. This simple application demonstrates possibilities and achievements of the reciprocal transaction modeling in the form of the CC-CP model.
