Problem statement:Specialised business processes, methods and IT systems for each survey / output
Applying Enterprise Architecture
Disseminate
... but if each statistical organisation works by themselves ...
... we get this ...
.. which makes it hard toshare and reuse!
… but if statistical organisations work together to define a common
statistical production architecture ...
... sharing is easier!

CSPA Service
2013 - CSPA development project
Architecture Proof of Concept
The Proof of Concept
5 countries built CSPA services
3 countries implemented them
What did we prove?
CSPA is practical and can be implemented by various agenciesin a consistent way
You can fit CSPA statisticalservices into existing processes
Statistics New Zealand (Workflow)
Istat (CORE)
CSPA does not depend on aspecific technology platform
Statistics New Zealand (Workflow)
Istat (CORE)
You can swap out CSPA compliant services easily
Statistics New Zealand (Workflow)
You can re-use the same statistical service by configuration
Survey A
Survey B
Statistics Sweden (Workflow -Triton)
Project Outcomes
The CSPA approach works
It promises increased:• sharing• interoperability• collaboration opportunities
Some licensing issues!

Architecture Working Group:Australia, Austria, Canada, France, Italy, Mexico, Netherlands, New Zealand, Turkey, Eurostat
Catalogue team:Australia, Canada, Italy, Hungary, New Zealand, Romania, Turkey, Eurostat
Architecture Working Group
Meetings every fortnight
25 Definition, Specification and Implementation reviews
30 architectural and implementation issues
Update of CSPA framework
CSPA Global Artefact Catalogue
Support efficient sharing and reuse of process patterns, information and services at an organization and international level
Allow users to reliably and efficiently discover what is available for reuse to support a particular business need
Allow users to assess whether services are "fit for purpose" to support a particular business need
Five layers of the CSPA Global Artefact Catalogue
2015 – CSPA Goes Live!
Main activities
1 Governance - management of CSPA and determining if services are CSPA compliant
2 Support to implementers - guidelines, templates and a helpdesk
3 More services – based on the priorities identified by project partners
4 Catalogue – transition from wiki prototype to full version hosted by Eurostat
Call for participation in project teams
Alignment with ESS Vision 2020
Alignment of CSPA (GSIM and GSBPM) and the implementation of the new ESS Vision is a key priority
From a CSPA perspective, the implementation of the ESS Vision is an excellent opportunity to test CSPA on a larger scale and to further develop it
Summary
Each standard can be used by itself
but
There is greater value in using them as a set of linked standards
