A parent movement in Connections[Beta] is used in situations where multiple movements function independently, but have a high level of cooperation in the fall, particularly with surveys. A good example of this is the University of Oregon team. The team is responsible for multiple movements (Destino, Impact, Cru, Greek Crossing, etc.). But, they use one fall outreach survey and do it together. Later, a local admin will copy or transfer the surveys to the appropriate movement(s) based on the expressed interest in the Audience or Ethnic Focused Communities.
NOTE: One downside to using the Parent movement model is that the SMS Subscription will only work for one movement on a Typeform survey.
