Managing the Implementation of SNA, BPM and Related International Standards in a NSO Context Authors: Derick Cullen and Bernard Williams Presenter: Michael Davies Australian Bureau of Statistics Aim of the paper To share ABS experience and lessons ABS implementing the new standards very early Changes SNA08 BPM6 Industrial classification: ANZSIC related to ISIC rev 4 impacts on frames, samples and outputs Institutional sector Big bang ABS implementing all changes at once: + minimises disruption for clients + reduces total cumulative effort: system, questionnaire changes balancing - makes it a very large task - can be difficult to disentangle individual impacts - not all standards / issues finalised in time - may not be as responsive to change Managing the change Governance structure and project management Communication with clients Methodological change Principles Principles Departures from standards Timing Coordination and consultation Principles (continued) Departures from standards: few in number & demonstrate a significant benefit or avoidance of an unwarranted cost carried through to all accounts/statistics enable a straightforward reconciliation with the standard where feasible be implemented after extensive consultation and publicity Principles (continued) Timing: implement at the same time as other changes implement at the same time across series Coordination and consultation: central coordination to ensure a consistent message sufficiently early equal opportunity to access information Principle - enable a straightforward reconciliation with the standard where feasible Rationale: ABS support for standards and international comparability only a couple of changes thought to be significant at the broadest levels thought would be relatively simple Reality: data generally not available detail of account compilation Rethink principle? Reconciliation principle - related issue As an early adopter of the standards should ABS reconcile to SNA93/BPM5? international comparability improved dilemma for ABS if both SNA93 and SNA08 versions of GDP: – which is the official statistic for Australia? –ABS will only publish one official GDP statistic (based on SNA08) –ABS will not allow recompiled data on SNA93 basis to be called Australia's GDP parallel systems Backcasting, bridging, parallel runs, seasonal adjustment How to maintain time series? How to determine seasonal patterns? ABS revises historical series to make them as continuous as possible: measuring level shifts backcasting or bridging series standard methodology applied assuming current seasonal patterns apply Implementation timing Reference period - September quarter 2009 2007-08 annual national accounts –source data from annual business surveys required for 2006-07 indicator series, e.g.: –July 2009 Retail trade –August 2009 International trade in goods and services –September quarter 2009 BoP & IIP Thank you
