Establishing E&I capability and best practices at Statistics NZ Vera Costa & Tracey Savage 2008 UNECE Work Session on Statistical Data Editing
Overview • Introduction • E&I Methodology Network • E&I Objectives • E&I Principles • E&I Strategy • The Pacific Island Attachment Programme • Current concerns • Conclusions
Introduction • E&I as a key issue within Statistics NZ • Context in which editing takes place has changed • Desire to improve the efficiency of data processing • Wider view of the objectives for E&I • Users’ demand for access to metadata
Introduction (cont.) • Approach used – development of: • E&I Objectives • E&I Principles • E&I Strategy • Development led by the E&I Methodology Network
E&I Methodology Network • Established in 2004 • Aims • Establish, document and promote E&I best practice • Provide information on E&I procedures and the quality of the data • Coordinate E&I skill development • Understand and research E&I
E&I Methodology Network (cont.) • Activities of the network • Development of E&I objectives, principles and strategy • Research into generalised E&I tools • Offering E&I training
E&I Objectives • Statistics NZ E&I objectives • Provide users with fit for purpose, plausible data and outputs by the most effective and efficient means • Ensure all users are better informed about the quality of our data and statistical outputs • Continuously improve our end-to-end business processes and overall data quality
E&I Principles • Importance of having E&I principles • Over-arching E&I principle‘Statistics NZ should maintain, wherever possible, the original data provided by the respondent or data supplier’ • Example of this principle in action – 2006 Census of Population and Dwellings Quality Management Strategy
E&I Strategy • Deliverables • E&I Plan template • E&I Standards and Guidelines • E&I Training
E&I Strategy (cont.) • E&I Plan • Developed for each family of outputs • Why have one? • raise issues related to prioritisation of different users’ needs • document the agreed E&I approach • manage users’ expectations about the quality of the final outputs
E&I Strategy (cont.) • E&I Plan (cont.) • How to create one • No ‘one size fits all’ • Discussions / workshops involving the Subject Matter Area(s) • What to take into account • User needs • Operational constraints • Lessons learnt
E&I Strategy (cont.) • E&I Standards & Guidelines • Why have them? – to ensure a consistent approach across similar outputs • Target areas • E&I processes, methods and tools • E&I metadata
E&I Strategy (cont.) • E&I Standards & Guidelines (cont.) • Deliverables • E&I Standards & Guidelines Document • E&I Manual • Presentations to promote the standards • Modular E&I training
Pacific Island Attachment Programme • What is it? • Focus of the 2006 / 2007 Programme ‘data quality and editing strategies encompassing both business and household data’ • Participant countries: Palau, Samoa, Tonga
Pacific Island Attachment Programme (cont.) • Challenges • Cultural differences • Totally different work environment • Heterogeneous range of work experiences
Pacific Island Attachment Programme (cont.) • Approach used • Providing an overview of E&I, focusing on • E&I concepts • How the knowledge could be applied back home • Avoiding mathematical expressions • Interacting with several Subject Matter Areas • Having a balance between • E&I training • Work on individual projects
Pacific Island Attachment Programme (cont.) • Relevant topics • E&I objectives and principles • E&I methodology (not too much detail or formulas) • Quality and E&I quality indicators • Documentation
Pacific Island Attachment Programme (cont.) • Achievements • Participants • Project completion • Advantages of a different approach when implementing E&I processes • Statistics NZ • Pilot for E&I training
Challenges facing Statistics NZ • Cultural changes • High staff turnover • Prioritisation of the work to be done
Conclusions • Importance of the E&I Network • Acknowledgements
