Standards-based Modernisaton
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 to
share and reuse!
… but if statistical organisations
work together to define a common
statistical production architecture ...
... sharing is easier!

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 agencies
in a consistent way
You can fit CSPA statistical
services into existing processes
Statistics New Zealand (Workflow)
Istat (CORE)
CSPA does not depend on a
specific 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 B
Statistics Sweden (Workflow -Triton)
Project Outcomes
The CSPA approach works
It promises increased:
•
sharing
• interoperability
• collaboration opportunities
Some licensing issues!

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

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
