In a first phase the questionnaire is designed. Respect to previous editions, new questions are inserted according to state-of-art measures. Anyway, along the different editions the core questions remained the same to ensure longitudinal comparisons.
After the design phase the questionnaire is tested and validated with some pilot companies. Thirdly, where necessary, the questionnaire is translated in the local language and sent out to companies. Every partner in every country manages the data collection in its own country performing also quality tests on the data (sample selection and representativeness, respondent bias, etc). Finally, responses are put together in unique and shared database.
Collected data are used for scientific purposes and to deliver reports and benchmarkings to the participating companies.
