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
