Why are longitudinal studies helpful?
Longitudinal studies can provide valuable insight into how participants behave and interact with their surroundings, an experience, or a brand over time in their everyday lives.
When should a longitudinal study be conducted?
Longitudinal studies can be conducted at any time during the lifecycle of a product. However, they are typically done:
- Before development, as a way to gather requirements and understand users
- After a site or product has been launched, to gather data on how, when, and why people naturally use it
