11.1. Quality assurance

Quality policy is defined and made available to the public in documents:

Quality declaration and Quality policy.The SOSR high level statements highlight customer orientation and quality of the SOSR products and services; this is then reflected in the development strategy of the SOSR for the given period of time in: Vision, mission, common shared values.

Quality Manual is covering all elements of the ISO 9001.

European Statistics Code of Practice is the backbone of the whole QMS.
11.2. Quality management - assessment

ACCURACY
13.1. Accuracy - overall

Most of checks are realised in the process of data entry automatically (number range, relations among the variables). Checks are realised also on the outputs. The errors are directly consulted with the reporting units. 

We apply various treatments to ensure that errors are minimised. Improvement actions include business registry updates, careful logical controls and constant contact with the reporting units.
