Repair is performed at customer site. If the machine cannot be fixed with the help of IBM remote support, the repair activity is performed by an IBM representative at the customer's site. Screening refers to the initial remote problem determination (PD) or problem source identification (PSI) activity on a customer's service request that is performed by technical support personnel. Typically this is the first technical activity performed after the service request has been entered into the call management system and the customer has been entitled. Call screening results in the creation of the initial action plan to resolve the service request.
