WHY ARE DYNAMIC DATA ATTACHMENTS IMPORTANT?
Respecting survey respondents’ time, as well as your own, is always a key priority. You can avoid survey fatigue by having relevant data that has already been collected automatically updated into future surveys, avoiding the repetition of any questions. This could mean, for example, creating a registration form of new project participants and then creating one or more surveys that include a unique identifier for each participant, allowing you to include relevant demographic data from the parent form instead of having to ask the same questions again.
Another important use case is phone surveys. As COVID-19 has restricted more face-to-face interviews, users have been conducting more interviews remotely using KoBoToolbox. Setting up a form to register phone survey participants as well as a second form to then collect data from each participant was possible before but now you can dynamically link two projects, meaning you can confirm personal details from the initial intake form before starting the interview. Likewise, using advanced XLSForm syntax, it is possible to automatically include relevant demographic details in the follow up survey so that they can be pre-filled during the survey, allowing updates as necessary.
Additionally, because two or more projects are linked dynamically, it is possible to continually update information in the parent project and the same details will be updated in the child project(s) minutes later. All survey projects will be completely up-to-date and your original data will still be maintained and unaffected by future surveys.
