REACTION TO UNDERPERFORMANCE OF FUNCTIONAL SYSTEMS

If the cause of the underperformance is found to be:

(a)     a flaw in the functional system, the service provider should initiate a change to the functional system either to remove the flaw or mitigate its effects;

(b)     a flawed argument associated with a change to that functional system, the service provider should either:

(1)     provide a valid argument; or

(2)     where the service provider considers it more feasible, initiate a change to the functional system.
