Managing the Implementation of
SNA, BPM and Related
International Standards in a NSO
Context

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
