The Structure of Earnings Survey (SES) is a series of four-yearly earnings surveys and provides information on relationships between the level of earnings, professional and individual characteristics of employees and their firms. The collection of data is very complex, as a result of information needed. In this view, the process has recently been re-engineered to run the SES 2010, in order to optimize data quality within existing constraints of time and budget. The focus of this work is on the problem related to managing a mixed mode data collection in order to achieve a consistent, integrated data base (data capturing and web questionnaire, use of administrative data and data integration). This paper aims to present the overall flow of the new survey process,
reporting for each stage the best practices and the first set of quality indicators, in an integrated E&I process and final data validation and publication.
