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
![Page 3: The Challenges](https://reader033.vdocuments.net/reader033/viewer/2022051518/5681660a550346895dd9435e/html5/thumbnails/3.jpg)
These challenges are too big for statistical organisations to tackle on their own.
We need to work together

The GSBPM
![Page 7: The Challenges](https://reader033.vdocuments.net/reader033/viewer/2022051518/5681660a550346895dd9435e/html5/thumbnails/7.jpg)
Information objects
• Things that flow between GSBPM sub-processes
• Things that drive and integrate sub-processes
![Page 8: The Challenges](https://reader033.vdocuments.net/reader033/viewer/2022051518/5681660a550346895dd9435e/html5/thumbnails/8.jpg)
GSIM is complementary to GSBPMAnother model is needed to describe
information objects and flows within the statistical business process
![Page 9: The Challenges](https://reader033.vdocuments.net/reader033/viewer/2022051518/5681660a550346895dd9435e/html5/thumbnails/9.jpg)
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

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

GSIM is a conceptual model: It is a new way of thinking for statistical organizations

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

• Sprint 1 – Slovenia, February 2012• Sprint 2 – Republic of Korea, April 2012• Integration Workshop, Netherlands,
September 2012
