# Tracker Study

**Metaforms** allows you to set up a **Tracker Study. Tracker Study** is a survey project that is conducted in waves or rounds over time - such as weekly, monthly, or quarterly - while maintaining consistency in structure and logic across versions. \
\
Metaforms makes it easy to manage tracker studies by allowing users to update questionnaires, XML, and quota sheets for each round while preserving prior versions. \
\
This ensures efficient handling of edits, tracking changes, and syncing to Decipher without disrupting ongoing data collection.\
\
You can use Change Management in Metaforms to update your XML based on the updated versions of Questionnaire and revised studies.
