Definition of Preventive action:
An action taken to reduce or eliminate the probability of specific undesirable events from happening in the future. Preventative actions are generally less costly than mitigating the effects of negative events after they occur, but may also be seen as a waste of resources if the predicted event does not take place. Risk analysis and assessment techniques are used to calculate the probability of specific negative events, in order to determine the cost-effectiveness of potential preventative actions.
