resource & social conditions are changing from human use. Good indicators:
SpecificObjective
Reliable/repeatableRelated to visitor use
Sensitive to visitor use over a relatively short time
Manageable
Efficient & effective to measureSignificanthelpdefine the quality of the visitor experience

Management actions can be traced back to specificproblems (via indicators).
