Step 1: Identify and define the problem and desired replacement behavior.
Step 2: Collect data
Step 3: Identify the function of the behavior.
These steps are important because you need an identified problem to have an FBA, data to show it is occurring, and what comes out of the data to show the pattern(s) in hopes of identifying the function of the behavior. All the above steps need to be in place to determine a 'problem' and then data to show a problem has correctly been identified.
