Generic Statistical Information Model (GSIM)
Thérèse Lalor United Nations Economic Commission for Europe (UNECE)
The Challenges
Increasing cost & difficulty of
acquiring dataNew competitors
& changing expectations
Rapid changes in the environment
Competition for skilled resources
Reducing budget
Riding the big data wave
These challenges are too big for statistical organisations to tackle on their own.
We need to work together

Information objects
• Things that flow between GSBPM sub-processes
• Things that drive and integrate sub-processes
GSIM is complementary to GSBPMAnother model is needed to describe
information objects and flows within the statistical business process
So what is GSIM?
• A reference framework of information objects:– Definitions– Attributes– Relationships
• GSIM aligns with relevant standards such as DDI and SDMX
GSIM gives us standard terminology
Business Production
ConceptsStructures
How to use GSIM as a communication tool
• Improve communication • Simple, easy to understand views of
complex information• Build staff capability by using GSIM as a
teaching aid

Can I implement
GSIM?
GSIM: The “sprint’ approach The HLG decided to accelerate the development of the GSIM using an Agile approach.
Sprints• Collaboration of multi-disciplinary
experts • A “time-boxed” period of work, and • A closely defined and agreed output
GSIM: The “sprint’ approach
• Sprint 1 – Slovenia, February 2012• Sprint 2 – Republic of Korea, April 2012• Integration Workshop, Netherlands,
September 2012
Developing GSIM
