1. On Tap: Developments in Statistical Data Editing at Statistics New Zealand Paper by Allyson Seyb, Felibel Zabala and Les Cochran Presented by Felibel Zabala Sept 2012

2. Aim of paper To describe the latest developments in Statistics New Zealand’s economic and household processing platforms 2

3. Strategic Developments Statistics 2020 Te Kāpehu Whetū - Recent actions Reduction in number of tools Use of Colectica to centralise storage of all information of Statistics NZ’s outputs Establishment of processes to research and introduce new standard methods and tools 3

4. Strategic Developments (cont’d) International collaboration Regular bilateral and trilateral meetings with various national statistical offices Involvement in the Statistical Networks on Confidentiality and the Industrialisation of Editing Continued investigation on the use of SELEKT Evaluation of SAS2Argus 4

5. Platforms Need for new infrastructure to produce statistics that are fit for purpose in a cost and effective way A platform is a logical cluster of functionality that enables components to be put together to provide a complete end-to-end system 5

7. Household platform Is a second generation platform with the design informed by an evaluation of the interim platform Processes and in the future analyse three social surveys and their supplements Uses standard tools to load, code, micro-edit and finalise a unit record dataset Processes a Blaise-based survey 7

10. Micro-economic Platform Previously referred to as BESt platform Processes and analyses economic surveys and administrative data collections Also has elements of ‘Develop and Design’, ‘Build’, ‘Collect’ (from general Business Process Model) Has a user configurable workflow Allows incremental statistical maintenance and uses standard tools for common processes 10

12. Challenges and lessons learnt Balancing generic and specific needs Determining process elements suitable to be implemented as common services Moving from a process culture to a more constructive innovative culture Key enabler of the culture change - the adoption of an agile project management approach for IT development projects 12

13. Moving forward Review of Statistics NZ’s generic Business Process Model Implementation of a framework to measure and report on the benefits achieved with recent and on-going developments Transformation of the organisation’s data collection processes 13
