2. Integrated statistical production process - CVD
CVD = Cycle de Vie des Données / Data Life Cycle
Four major stages :
Data Collection or Data Transmission
Data Validation
Statistical Production
Data Dissemination
Objective: Rationalise the IT systems for statistical productions 2

3. Integrated statistical production process - CVD
The project was launched at the end of 2002 with seven internal CVD groups:
Conceptual framework and metadata
Data transmission
Data validation
Production systems and internal reference
Data confidentiality
Statistical Analysis
Dissemination and Eurostat Portal
Mission: define user requirements for each step of the CVD 2

4. Integrated statistical production process - CVD
New CVD project (July – December 2004)
Deliverables:
Typology and categorisation of processes & flows - selection of representative sample to analyse
Analysis of descriptions of statistical production processes (PIM plus other documentation sources)
Identification of re-usable building blocks (“software components”)
Definition of standards and guidelines for documentation of statistical applications 2

5. Integrated statistical production process - CVD
Project’s main benefits:
Risky system identification
Harmonised and comprehensive application/system documentation
Cost reduction (maintenance and development)
Redeployment of effort 2
