Eurostat
Industrialisation of statistical production
• Streamlining and integration of the European social surveys has three objectives:• increase efficiency• increase responsiveness • increase the level of interlinking

Modularisation
• Modularisation criteria• Highly conditioned by filtering• Dependencies between modules & hierarchy
• Standardisation• Generic nature of modules
• A work in progress• To soon to answer definitely to “What is
module?”
Eurostat

Eurostat
Modular survey architecture
• Plug-and-play• Standardised modules• Modules combined into “instruments”
• An instrument is an answer to the need for certain joint distributions
• Data collected per instrument• Data for one same module collected via different
instruments is combined
Eurostat
Modularity in the stages of production
Eurostat
Centralisation of data collection – initial reflexions
• Needs• Higher number of different questionnaires• For each questionnaire, smaller samples• Data collection does not serve a survey, but a
more complex data processing system• Focus on make the best use of the interview time• Module dependent multi-mode data collection
Eurostat
Centralisation of data collection – initial reflexions
• Opportunities• Shorter questionnaires• Higher harmonisation -> Efficiency• Modular questionnaire design• Re-use of manuals, explanatory notes, training
