The Common Statistical Production Architecture (CSPA) was developed during 2013 in an international collaboration project under the High-Level Group for the Modernisation of Statistical Production and Services (HLG). That project included the development and specification of the architecture, as well as a practical test of its principles and applicability in a “proof of concept”. However, given the strict time limits for that project (one year), it deliberately did not include the implementation of the architecture for production systems within statistical organisations. A follow-up project to cover early implementations and the development of key supporting resources such as a catalogue of artefacts, was seen as a top priority by the Workshop on Modernisation of Statistical Production and Services (Geneva, 25-27 November 2013). The HLG subsequently agreed that this should form one of two key modernisation projects for 2014.

By the end of 2014, this project aims to create the first “production” CSPA-compliant services, and implement them in several statistical organisations. It will not create the full set of services needed for all statistical production activities, but it will show how this could be done. It will result in the practical application of CSPA, and could result in enhancements to the architecture based on implementation experiences.

The project is open to all national and international statistical organisations that want to contribute. It aims to be complementary to other initiatives, including those of the Statistical Network and the European Statistical System, and to avoid duplication of efforts. It also aims to be as relevant as possible to the organization-specific needs and concerns of each contributing organisation.
