International Conference on Establishment Surveys 1 Everything you wanted to know about Electronic Data Reporting (EDR) at Statistics Canada June 2007
International Conference on Establishment Surveys 2 Outline of Presentation Introduction Background Original approach for EDR Services What happened? Consequences Electronic Collection Framework Summary/Conclusions
International Conference on Establishment Surveys 3 Introduction Statistics Canada (STC) began using Electronic Data Reporting 10 years ago by mailing questionnaires on diskettes. Six years ago a Government On-line initiative was launched; STC awarded funding to develop a comprehensive Internet collection platform.
International Conference on Establishment Surveys 4 Introduction Project originally focused on developing an EDR solution for 50 business and agriculture surveys, since these respondents complete large numbers of surveys on an ongoing basis. Since then, the 2006 Census provided a customized electronic data reporting option, and achieved a 20% take-up rate on the household side. Today, Statistics Canada has a new plan to provide electronic collection service to respondents, based on last 5 years of somewhat painful experience.
International Conference on Establishment Surveys 5 Background STC administers over 400 surveys across four business lines: social, institutional, agricultural and business. Computer assisted telephone interviewing (CATI) and personal interviewing (CAPI) are the mode of collection for social surveys; paper as well as CATI are used for agriculture, business and institutional surveys.
International Conference on Establishment Surveys 6 Background Strict confidentiality and privacy policies require a sophisticated security model for EDR, along with a complex technical infrastructure. The wide diversity in STC’s surveys (complexity, length, frequency, sample size) added to the challenges for developing EDR applications.
International Conference on Establishment Surveys 7 Original Approach for EDR Services Introduced EDR to small surveys or sub samples of larger business/agriculture surveys to minimize potential reduction in response rates. Original mode (usually paper) kept as an option for respondents. Selected sub-annual surveys whenever possible. Created separate EDR applications and integrated later with other collection streams (e.g. CATI and paper).
International Conference on Establishment Surveys 8 Original Approach Web-based and Excel-based options developed to handle different requirements for different surveys. Web-based option used HTML, Java Script. Both options used PKI-Entrust (which required respondents to download a Java Applet on a JVM).
International Conference on Establishment Surveys 9 Original Approach Created secure staging area physically separate from the Internet and STC’s internal network for maximum security. Built authentication and encryption services, along with virus and detection capability. Implemented a “Thick client” model (edits executed on client-side).
International Conference on Establishment Surveys 10 What Happened? Unable to assess cost/benefit of EDR as a mode of collection, given small EDR sample sizes. Response rates varied (0% - 60%). Technical infrastructure not stable due to high level of complexity. Respondents had technical difficulties accessing site and completing surveys.
International Conference on Establishment Surveys 11 What Happened? Costs to develop and support 50 unique applications too high. EDR with a CATI follow-up (i.e. multiple, independent systems) does not provide significant benefits (time or money). Surveys adopting EDR need to develop their collection approach from a single instrument point of view. Overall - minimum success achieved with majority of surveys originally selected for EDR.
International Conference on Establishment Surveys 12 Consequences Undertook a complete review of Statistics Canada’s approach to EDR services. Statistics Canada moving towards a simpler, more technically integrated collection environment. Proceeded to adopt an enterprise wide view of collection with a more generic/integrated approach across modes. Adopted new standards for surveys wanting to offer an EDR option (e.g. minimum sample of 6,000). Developed an Electronic Collection Framework outlining short to medium term strategy for EDR.
International Conference on Establishment Surveys 13 Electronic Collection Framework Stabilize current EDR environment Gather Business Requirements Conduct Options Analysis Conduct Pilots The Way Forward
International Conference on Establishment Surveys 14 Electronic Collection Framework Stabilize Current EDR Environment (Completed) Documented all outstanding issues Created lessons learned document Reduced existing suite of EDR surveys to only those with a good business case Implemented upgrades to environment based on maximum improvement for minimum cost
International Conference on Establishment Surveys 15 Electronic Collection Framework Gather Business Requirements (Completed) Conducted an Agency wide analysis of the business requirements for EDR. Involved 40 divisions and all types of surveys Produced the “STC Electronic Collection Services”, a summary of requirements Identified the need for 2 core electronic services e-file transfer service (urgent) e-questionnaire service
International Conference on Establishment Surveys 16 Electronic Collection Framework e-file transfer service a secure service to collect (& share) survey related administrative files bi-directional: serves STC and its partners based on the “Managed File Transfer” Technology e-questionnaire service a self-administered questionnaire service Enables respondents to securely fill and submit surveys online (internet)
International Conference on Establishment Surveys 17 Electronic Collection Framework Conduct Options Analysis (Completed) Assessed buy (using COTS) vs build software for new infrastructure Identified 10-12 potential COTS products aligned with each of the 2 core services Undertook detailed analysis of key products
International Conference on Establishment Surveys 18 Electronic Collection Framework Conduct Pilots (in progress) Obtained free access to 2 COTS products Record STC hands-on experience Gather end-user feedback e-file transfer pilot (complete) 9 Divisions, 5 External Partners Very positive feedback e-questionnaire pilot (underway) 2 social surveys participating in pilot as well as business survey
International Conference on Establishment Surveys 19 Electronic Collection Framework Way Forward Obtain corporate approval for Electronic Collection Framework Strategy/Business Case Complete e-questionnaire Pilot Undertake competitive processes for both e-file transfer and e-form COTS software Launch Agency wide e-file transfer service spring 2008 Offer limited e-questionnaire service summer 2008
International Conference on Establishment Surveys 20 Summary/Conclusions Difficult start up for EDR at Statistics Canada New approach of integration and simplification of collection processes helping to redefine the role of EDR in future Consultation exercise established priorities for e- services. Re-engineering of current infrastructure under way (subject to funding approval) Increasing interest by Social Surveys Future looks promising
