Philosophically speaking it is invaluable to have all rescuers on the same page to ensure an "EXCELLENT" Rescue.

Self Rescue, Rescue Team, Bystanders, Unstable Subjects, Stable Subjects, Equipment

Most rescues require rescues to be performed in the following sequence: Locate, Access, Stabilize, Transport

This model promotes rescuer safety by reducing their exposure to risk

Talk, Reach, throw, Row, Go, Tow, Specialty Rescue (Helo/Scuba)

Use the most effective technique first AS LONG AS it is below your (your group's) Acceptable Level of Risk (ALR).  Consistently i the situation by asking "Can I (do this), Should I (do this)". Only take a particular action if you can answer with a double affirmative "YES I Can and YES I Should"

Leadership (assign roles, change the plan, take charge of transitions, assign medical evaluation, transport

decision) 

Safety (establish downstream perimeter, containment, rescue ready)

Rescuers (access, stabilize the subject, once stable look to Leadership for transport options)

 

Rescuers predetermine their organization with Leadership, Safety and Rescuers (in that order). This is often seen is professional rescue services such as the military, police, civil protection and fire service.

Stable Subject (ability to signal, not obviously injured, stationary): Leadership, Safety, Rescuers
