Hello, 
I am currently having an issue with workflow and was hoping you can help me out. I need a way to make it stop triggering once those tasks have already been created once. 

I currently have a workflow set to trigger a set of tasks as follows:
created, and every time it’s edited
AND( 
ISPICKVAL( StageName , "Pilot Implementation Pending"), 
NOT( ISPICKVAL( PRIORVALUE(StageName) , "Pilot Passed Back For Assistance") ))&& ( Account.Owner.UserRole.Name = "Implementation Team")


Any help would be greatfully appreciated.
