  • Starting points
  • Design
  • Results so far
  • Improvements longer run

  • Challenges to Statistics Netherlands
  • Improve quality of statistics

  • Top-down approach
  • Chain management
  • Architecture uniformity of processes

5
Starting points STS (1)
  • Background
  • Growth rates of monthly and quarterly turnover
  • Different branches
  • Three releases s30, s60, s120
  • Yearly 374 000 forms
  • Yearly 274 000 forms for small and medium-sized
    units (SMB, lt 50 employees per enterprise )
  • Redesign use VAT data for SMB

6
Starting points STS (2)
  • Requirements
  • Coherence monthly, quarterly and yearly turnover

Starting points STS (3)
  • Issues
  • Monthly, quarterly and yearly reporters of VAT
  • Fiscal unit nm relationship with enterprise
  • First release s30, start process VAT-data s23
  • Definition of VAT turnover ltgt statistical
    definition
  • Detection of erroneous values

    of monthly turnover (issue 1 3)

8
Design (1) estimator
  • Yearly growth rate (G) of monthly turnover (O)
  • S stayers, B births, MI immigrants
  • Motivation
  • Yearly growth rates more alike than levels
  • Monthly versus quarterly and yearly reporters
    (issue 1)
  • Linked units versus non-linked units (issue 2)
  • Early versus late reporters (issue 3)
  • VAT-definition versus statistical definition
    (issue 4)

9
Design (2) processing stages
  • Comply with business architecture
  • Value chain
  • each process add value to the data
  • generic structure
  • Steady states
  • well defined state of processing
  • quality indicators
  • re-use of data

Results so far
  • Requirement (1) Coherence
  • Monthly, quarterly and yearly turnover consistent
  • Yearly turnover VAT for both STS SBS (in
    future)
  • Requirement (2) Difference between releases
  • Difference still gt 1.5 point
  • Editing should be improved
  • Population dynamics
  • Requirement (3) Publish on time
  • Yes but processing time for editing is short

12
Challenges
  • Improve linkage between fiscal and statistical
    units
