18. Good Practice 2
Make things as non-
invasive as possible
for the user experience
of mobile device.

19. Short survey length is a key to
lower attrition rates - no more
than 10-15 minutes - or break
into chunks if possible. If not
possible - embed most critical
questions in the first 10 minutes
of survey.
