Monthly tendency survey in the building industry 2021
Gestion de la qualité
Quality assurance
The monthly business tendency survey in the building industry is part of the European
system to harmonise European Commission business outlook surveys, and to which the
27 Member States of the European Union contribute.
Thus questionnaires, survey frequency and scope, classifications and data processing
methods have been harmonised to a large extent in the national institutions of the
programme partner countries.
The questions are formulated so that they can be answered quickly (most of the questions
are qualitative with three response options expressed in the form "higher, stable,
lower", or "more than normal, normal, less than normal").
