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
