The Workshop deliverables provide a basic framework for interoperability in pan-European electronic transactions expressed as a set of technical specifications. The scope is public procurement but the specifications apply as well to private trade.

The BII specifications are expressed as a set of “profiles” for specific parts of the public procurement processes, and include validation tools to implement them correctly.  The specifications are documented as CEN Workshops Agreements (CWAs) and are freely available for use.

At the closing meeting of CEN WS/BII1 (phase 1 of the workshop) the CWA 16073:2010  was approved for publication, including five parts:
Part 0: Introduction
Part 1: Profile overview
Part 2: Convergence and gap analyses
Part 3: Toolbox for technical interoperability
Part 4: Evaluation guidelines for testing and piloting

The results of the CEN WS/BII Phase 1 (see are the basis for the Phase 2 Work.

The goal of CEN WS/BII2 (phase 2 of the workshop) in terms of deliverables was to update, integrate and extend the scope of CWA 16073:2010. Throughout its lifecycle, the second phase of the Workshop focused on capturing new (and refining the existing) business requirements. The Workshop also worked to express those requirements independent of any specific syntax, and in order to make this result usable, to link the requirements to some of the most commonly used standards, binding them to the syntax of OASIS UBL and UN/CEFACT.

The CEN WS/BII3 (phase 3 of the workshop) is currently continuing the work initiated by CEN WS/BII, and further refined under CEN WS/BII2, to support interoperable electronic procurement and business solutions. In order to achieve this, CEN WS/BII3 has the objective to provide increased value to the CEN WS/BII user community, by:

  • Filling the gaps to ensure that all relevant aspects of eProcurement are covered
  • Facilitate increased use through capacity building
  • Securing the continued relevance of the BII deliverables by providing a focal point for governance and lifecycle management
