Planning a team trip is no small undertaking! It makes sense to have a small group of people involved in this, to help cover all the required actions and share the load. This group may be the mission committee, church leadership, a combination of both or a specifically created group altogether.
NB: The following relates to the planning of a team without the involvement of an agency. Should an agency be involved, they are likely to oversee all aspects of logistics which will significantly lift the load from the group and team leader however the church/group will still need to be aware of much of these details.
