1. Applying the ESS EARF in a VIP project: The ESS.VIP Validation example

Eurostat, Unit B1

2. ESS Vision 2020
"We will develop an ESS reference enterprise architecture to enable a systematic and coherent approach to the production of European statistics." 
"We will adopt enterprise architecture as a common reference framework"

3. ESS.VIP Validation example

4. What is Data validation?
ESS Methodological handbook on validation:
"Data Validation is an activity verifying whether or not a combination of values is a member of a set of acceptable combinations."
It is not:
An activity to check or assess process metadata: validation focuses on data
Editing or imputation: these are separate activities which may be performed based on the outcomes of validation

5. Focus of ESS.VIP Validation
Member
State
Eurostat
Validation can take place in several points of the ESS statistical production process

6. Current situation

7. Current problems in ESS validation
No clear picture of who in the ESS is doing what as regards validation:
Risk of validation gaps
Time-consuming validation "ping-pong"
Subjective assessment of data quality
Lack of standards and of a common architecture for shareable and reusable validation services:
Duplication of IT development costs within the ESS
Manual work due to low integration between the different tools

8. Step 1: Identify target capabilities

9. Step 2: Find pain points in current state
Capability 2
Capability 1

10. Step 3: Draw to-be situation

11. Step 3: Draw to-be situation
Process step name

12. Step 3: Draw to-be situation Business-Information Link
Process step inputs
Process step outputs

13. Step 3: Draw to-be situation Information - Application Link

14. Step 3: Draw to-be situation
Application Layer

15. Step 3: Draw to-be situation Collaboration scenarios

16. Step 4: Down to the logical level Information layer
Determine implementation standards for GSIM objects identified:
Data structure: SDMX
Validation rules: VTL
Etc…

17. Step 4: Down to the logical level Application layer

18. Step 5: Physical level

19. Benefits from the approach
Clear translation of strategic objectives into operational tasks
Clear communication across organisations
