In a reaction to the Wiesbaden Memorandum EUROSTAT called for proposals placing central innovative tools and sources for diary based surveys. The focus lies on the Time-Use Survey and the Household Budget Survey. To collect TUS-data, member countries rely since 2004 on a pre-harmonisation strategy outlined in the HETUS-guidelines, which, in place, have resulted in highly comparable and highly valuable international data employed within a wide range of study domains (paid work, unpaid work, gender equality, leisure, …). A downside is that these data collections are paper-and-pencil based, with a negative impact on budget costs, response rates and respondent burden. To overcome these downsides the Research Group TOR of the Vrije Universiteit Brussel (Belgium) began in 2012 the development of a software platform named Modular Online Time Use Survey - MOTUS. Besides maintaining comparability, reliability and quality as preconditions, the real strength lies within the modularity of the tool. Due to its software architecture new features and coming innovative methodologies can be added, including behavioural data coming from wearables or metering devices to enrich the context of daily human behaviour even further (i.e. to study the subjective experiences like stress and the objective experiences like calorie burning). This poster presents the (selected) SOURCE TM project and brings together STATBEL (Statistics Belgium) and DESTATIS (Statistics Germany) in their interest to get to know more about the MOTUS. This EU-grant project will evaluate how and in which way MOTUS as a tool or software platform can be adopted by STATBEL and/or DESTATIS, and furthermore can be ESS-shareable. The projects starts February 2019. The poster presentation and future work within the project is a collaboration between: Joeri Minnen (Vrije Universiteit Brussel - hbits), Kelly Sabbe (STATBEL) and Hubertus Cloodt (EUROSTAT).
