Drivers for centralizing data collection:
Achieving efficiency by:• Abolishing redundant processes, workflows, and
activities for social and business surveys• Monitoring processes, workflows, and activities
• Abolishing redundant systems and tools• One data collection management system• Maintaining as less systems and tools as needed
Spin off• Clear and professional external focus• Reducing response burden

Organizing Data Collection
Front desk:• Client relations• Survey design
Design:• Questionnaire• Sampling• Training
Survey deployment:
• CAPI / CATI Interviewing
• Planning & control• Fieldwork logistics• Support• Special services
Clustering of practices and knowledge• Focus on how knowledge is being used

Process-and-knowledge driven approach:
Survey deployment
CATI unit• Interviewing R• Telephone
CAPI unit• Interviewing R• Face-to-face
Help desk• Support R• Telephone
• Technology driven: use of telephone• Processes, workflows and skills are different• Processes, workflows and skills are comparable
Re-organising Telephone and interviewing units
59th Conference of European Statistics (CES), 14 June 2011, Geneva59th Conference of European Statisticians (CES), 14 June 2011, Geneva 7
Process-and-knowledge driven approach: Introducing home-based interviewing
• Phase 1: for CATI agents €100k• Phase 2 (ongoing): for CAPI interviewers €400k
Revenues:• Flexible cost efficient CATI / CAPI workforce• Remain nationwide CAPI coverage• Improved communication• Prevent slack demand – supply CAPI workforce
Survey deployment

To be ready for the future
• Reliable statistics:• relevant• more & integrated information• faster
• Less money• improving cost-efficiency
• Less compliance costs• reduction of response burden
• Implementation of Data Collection Strategy
59th Conference of European Statistics (CES), 14 June 2011, Geneva59th Conference of European Statisticians (CES), 14 June 2011, Geneva 9
The 2011 Data Collection Strategy:Retrieving and returning
3 steps:1. Re-use of available data
• Data sharing & data warehousing
2. Use of new registers and other secondary sources • Traditional government-based registers • Information from private businesses
• Data on the internet (web-crawlers)
3. Primary data collection:1. EDI technologies, like XBRL
2. Web surveys 3. traditional modes: paper, CATI, CAPI
• Using new social media technologies • Reciprocity: report back to respondents
Multi-source designs
Mixed-mode designs
59th Conference of European Statistics (CES), 14 June 2011, Geneva59th Conference of European Statisticians (CES), 14 June 2011, Geneva 10
How to achieve this?
• Data Collection Division: • Coordinated data collection for social and business surveys• Mixed-mode designs
• Data Service Centre & Social Statistical Database: • Data warehousing
• Research (in collaboration with Methodology Division):• Statistical methods for combining data sources• New sources • EDI techniques • Web survey methodology, mixed-mode surveys, pre-testing • New media
• Survey-based projects:• Re-designing chain of Economic Statistics:
- using more register data / XBRL / Web questionnaires • Re-design of Social Surveys: - developing web questionnaires

Data collection:Developments over the years
• From stove-pipes to a coordinated system of data collection
• From single surveys to multi-source/mixed-mode data collection designs
• From single-survey managers to managers of integrated sets statistics
• From local decision making to corporate decision making
• From data collection to data retrieving and returning
