2.1 Statistical information model

 

2.2 Adoption of GSIM

 

2.3 Statistical business process model

Statistical survey life cycle


SMS is an integral part of SIS.
The main goal of the SMS is to support the statistical business process (collection, production and dissemination of statistical information).
The following scheme demonstrates the structure of the process: 

Main functions of individual phases of SBP:

Users´ requirements

Assessment and evaluation of users' requirements in link with already existing statistical tasks. Consideration of capacity requirements, etc. This phase includes an evaluation by subject-matter departments and methodology department. It also includes decision-making by the top management of the CZSO. It results in approval or disapproval of users´ requirements.
  
Definition of statistical task (DESIGN)
In case of a new ST, a specification of the content, organisation and technology of the ST is made. This includes the proposal of task concept, definition of statistical variables, definition of statistical samples, outputs, definition of statistical questionnaires, other input data sets (from administrative data sources, from other statistical tasks), calculation description over the data (imputation methods, aggregations, calculation of derived statistical variables), time-table for ST preparation and implementation, etc. 
In case of an existing ST, its update should be prepared.
This phase is in the responsibility of subject-matter department and methodology department.
Preparation of data processing (BUILD)
Namely the following activities should be made: 

  • selection of samples,
  • preparation and distribution of questionnaires (incl. electronic questionnaires),
  • training of interviewers and staff responsible for individual phases of production,
  • getting data sets from administrative and other external data sources.

This phase is in the responsibility of data processing department and subject-matter department.

Data collection (COLLECT)
Namely the following activities are included:

  • collection of questionnaires and input data capture,
  • data validation,
  • use of data from other data sources (incl. data validation),
  • imputation and creation of input data sets for further processing.

This phase is in the responsibility of data processing department and subject- matter departments.

Data processing (PROCESS)
Namely the following activities are included:

  • building of input database,
  • imputation of missing records,
  • grossing up to statistical population,
  • processing of aggregates,
  • adjustment for seasonal effects,
  • database update.

This phase is in the responsibility of data processing department in cooperation with subject-matter departments.


Data analysis and output production (ANALYSE)
Namely the following activities are included:

  • application of mathematical and statistical methods,
  • processing of required outputs,
  • data quality assessment,
  • approval of data for publication,
  • public database update.

This phase is in the responsibility of subject-matter departments.

Dissemination (DISSEMINATE)
This phase focuses on the following forms of data dissemination:
- web pages,
- public database,
- printed publications,
- electronic outputs,
- ad hoc outputs.


Other activities:
- users´satisfaction surveys,
- analyses of the use of disseminated statistical information,
- statistical confidentiality.

This phase is in the responsibility of dissemination department and selected subject-matter departments. 
The basic scheme of the statistical business process (survey life cycle) has been updated according to the draft Statistical Business Process Model prepared by the UNECE Statistical Division (Oct. 2008)
