2.1 Statistical information model


2.2 Adoption of GSIM


2.3 Statistical business process model

13. Statistical activity of UNIDO started with establishment of Industrial Statistics database in 1977 to meet the internal needs of the organization for an accurate assessment of structure and growth of industrial sector. In terms of the external data sources UNIDO was dependent to the United Nations Statistics Division, which used to collect the data from national statistical offices. In 1993 UN Statistical Commission at its twenty-seventh session granted mandate to UNIDO in collaboration with OECD for collection, maintenance and dissemination of worldwide key industrial statistics.

14. Currently UNIDO maintains industrial statistics databases or INDSTAT databases which are regularly updated with the data collected from National Statistical Offices (NSOs) and OECD (for OECD member countries). UNIDO also collects national account related data from National Accounts Main Aggregate Database of UNSD, the World Development Indicators of the World Bank and other secondary sources. Further in this paper mainly the INDSTAT databases will be considered and other data sources will be mentioned only as needed as complimentary data for particular statistical dissemination products. Thus the statistical data production life cycle model of UNIDO (we do not talk about statistical survey life cycle) consists of collection, development, maintenance and dissemination of worldwide key industrial statistics at detailed sub-sectoral levels of the manufacturing sector of industrial production in individual countries.

15. The process of statistical production in UNIDO has an annual cycle and can be summarized as follows. Elsewhere in this document each phase of the lifecycle is described in more detail.

  • Initialisation: [Q1] Pre-filling of the out-going UNIDO General Industrial Statistics Questionnaire with previously reported statistical data and metadata for their possible revision by the NSO. The questionnaire is created in Excel format in one of the three languages (English, French or Spanish) appropriate for the particular country. The prefilling is automated using the available data and metadata; 
  • Data Collection (NSO): [Q2-Q3] The completed and returned to UNIDO by the NSO questionnaires (excel format, rarely hard copy) are entered into the system and are ready for further validation and processing;
  • Data Collection (OECD): [Q3] Data for OECD member countries, collected through joint OECD/UNIDO questionnaire and transmitted to UNIDO (excel format) are entered into the system and are ready for further validation and processing; 
  • Transformation/Processing: [Q3-Q4] The data collected from the primary sources are further transformed to a ready-to use data set. The data transformation is done in five stages, which not only constitute an operational framework for UNIDO statisticians, but also provides additional description of statistics (generated metadata which is attributed to each data item) to users.
  •   Dissemination: [Q4-Q1] After undergoing the complete processing phase the incoming and generated data and metadata are stored in the databases and the databases and can be used for production of the recurrent statistical publications: International Yearbook of Industrial Statistics, INDSTAT and IDSB CD products, Web Country Statistics. 

16. Similarly to the survey life cycle defined by the METIS group, at the beginning can be an optional
'Need' phase in which the necessity of changes in the questionnaire and processing is analysed. If changes are required, the respective 'Develop and Design' phase is in order. For example this year the metadata part of the questionnaire was evaluated and modified, which included translation into the three supported languages (English, French and Spanish).

17. The following Table 1 shows the mapping between METIS survey live cycle phases and the phases in the
UNIDO production process. Essential difference is that there are no explicit preparation phases like 'Need', 'Design and develop', but always at the beginning of the statistical production cycle the current status is analysed and if necessary the questionnaire as well as the process are updated. Further, there is no 'Archive' phase, since as soon as the data are processed completely they are stored in the UNIDO statistical databases and there is no need of special archiving procedure.
