Modeling a Retailer B2B Integration Portal as Choreography Intermediary with BPMN 2.0 Choreography Diagrams

In the retail industry, vendor integration in the supply chain is strategic to gain competitive market advantage. Supply chain integration has technological, organizational, planning, operational, and processes management aspects, and requires the integration of collaboration and cooperation processes of retailers and vendors to reduce the effects of information distortion in the logistics chain (bullwhip effect). B2B Integration Portals are key collaborative tools for information exchange and business processes, especially for logistics, business and financial processes. We propose to model B2B Portals as intermediaries among choreography model parties, which are finally implemented using ESB-type applications. The approach is illustrated by analyzing a Chilean retail vendor integrated logistics, which is modeled using choreography and conversation models and the new BPMN 2.0 choreography diagrams. An empirical validation approach is also suggested and ongoing in real projects.
