Why would you determine action to take, but not take the action? Let's see how that logic would work with another important clause of the standard:
By the logic above, we would determine the processes of the system, but not actually
implement them. We would determine interactions of the processes, but not actually
have interactions. We would also determine criteria and methods to ensure that the processes were effective, but
choose instead to have ineffective processes. Oh wait -- the processes coudn't be effective anyway because we didn't implement them to begin with...
Essentially that logic rips the guts out of the whole QMS. No thanks. I choose to believe that if the standard requires us to determine something, it also requires us to implement it.
