Maximum tolerable period of disruption
MTPD / MTPoD
In French : Période maximale d'interruption tolérable
The time beyond which the consequences of disruption become unacceptable to the organisation. It is a ceiling, not a target.
Not to be confused with the RTO, which must sit strictly below it to leave a safety margin.
