SMS-QUALITY The project and application focused on metadata on quality
European conference on Quality in Official statistics3-5 June 2014, Vienna
2
■ Introduction - aims, features, coverage, current state
■ Architecture - Q-attributes, hierarchical structure, design, preparation, data retrievals and inputs, functionality, stability of values and updates
■ Benchmarking
■ Challenges
Topics
3
Starting points
■ Horizontal way of management
■ Demands for quality reporting & relevant metadata ‚standardisation‘
■ Standardisation of quality reports & adjustments for domain statistics
Tool for managers
■ Semi-interactive cross-cutting overviews about quality of a survey (incl. assessments…)
■ Quality reporting
■ Application using web-browser environment
Reasons and Aims
4
■ Q reporting focused on a survey (of any kind) and groups of surveys
■ Cross-cutting info on quality of statistical process, output data and products
■ Data preferably retrieved from other source databases
■ Data monitoring, comparisons, aggregations, assessment, benchmarking
■ Flexibility of metadata content and possibility of survey’s adjustments
■ Help to improve quality reporting and statistical quality itself
■ Encourage self-assessment, support auditing
Aims and main features
5
■ The application is integrated within the internal SIS and SMS systems
■ Meta-data values retrieved from databases or manually inputted
■ Design & preparation of various quality reports
■ Hierarchical structure (refers to ESQR, GSBPM, DESAP)
■ Public vs. non-public – individual items or complete reports
■ Bilingual (multi-lingual) solution
■ Usual output formats PDF, HTML, XLS, DBF, DOC, not SDMX
■ User roles: admin, owner, editors, viewers (public vs. internal)
Features
6
Other SMS subsystems can provide certain knowledge on quality criteria e.g. accuracy, relevance, accessibility, clarity, timeliness, punctuality.
■ SMS SURVEYS: statistical processes (particular surveys)
■ SMS REQUIREMENTS: management of main user requirements
■ SMS DISSEMINATION, CATALOGUE OF PUBLICATIONS:
dissemination, product quality, info service
in some cases in relation to concrete surveys
Interlinks with other SMS-applications
7
Any statistical process processed or at least with its data stored in the central DWH.
■ Business statistics
■ Social and demography statistics
■ National accounts
■ Price statistics
■ Administrative data statistics.
Coverage
8
Type of info on quality - quantitative and qualitative:
■ Reference metadata
■ Info about process and its phases
■ Schedules
■ Quality performance indicators
■ Calculations
■ Benchmark results
■ Evaluation, (self-)assessments, commentaries
■ Textual, Numerical, Date
Q-attribute (item, meta-information, indicator)
9
■ Basic information (about a survey)
■ User requirements agenda
■ Methodology info
■ Time schedules; Timeliness; Punctuality
■ Statistical process phases
■ Data confidentiality and protection
■ Data sources; Frame; Sample
■ Outputs and dissemination
■ Individual quality criteria (i.e. quality dimensions)
■ Quality performance indicators
Categories of Q-attributes (info on…)
10
Relates to functionality (stability of values)
■ General
■ Statistical survey (key users, methodology, key statistical variables…)
■ Reference year
■ Processing (all reference periods processed or revised at one time)
■ Reference periods
Levels of Q-attributes
11
■ To provide relevant & up-to-date information
■ Validity for certain years, batches (i.e. processings), ref.periods
■ When generating data for new reference periods...
■ Metadata updates on each level
■ How to update the derived Q-Maps
■ Managers informed and decide via the application
■ Keeping history and updates
Updates of metadata structures and values
13
■ Structure (hierarchy): Sections, Sub-sections, Q-attributes
■ Q-Maps: monitoring, benchmarking
General - > Specific -> Survey Q-Maps design, specificationsValue Q-Maps output report
■ Q-Forms: also comparisons and aggregations…
General QM for Q-Forms -> Q-Form -> Value Q-Form
Q-Forms use (not only) Value Q-Maps as the source of data
Q-Maps & Q-Forms
14
Comparisons, aggregations over
■ Statistical variables
■ Reference periods
■ Surveys
■ Years…
Which data
■ Values
■ Benchmark results
Q-Forms - comparisons, aggregations
15
Design of a report
■ General Q-Map -> A type of report. General design, pre-setting of parameters.
■ Specific Q-Map -> A group of surveys.Selection of Q-attributes, way of benchmarking.
■ Survey Q-Map -> A survey Statistical variables, benchmark scales, links to data.
Output report
■ Value Q-Map -> One reference period.
Retrieval, editing, approval of values. Benchmarking.
Levels of Q-Maps - Hierarchy
16
■ Primarily for internal management purposes
■ Benchmarked values: numerical or textual
■ Adjustments of scales (boundaries) for particular surveys
■ Parameters
■ To benchmark or not to benchmark?
■ Manually (each value individually) or Automatically (pre-definitions)
■ Categories’ definition – number of categories, and either definition of boundaries or assignment of values from a nomenclature
■ Categories’ labelling – from a special nomenclature or directly in the app
Benchmarking
17
■ Deeper relations between subsystems
■ Revisions of quality attributes
■ Involvement of domain statisticians
■ Full implementation
■ ESS standard quality reports in SDMX
Challenges
