1. A method comprising the following steps: entering, by a service provider and a first customer, a first Service Level Agreement (“first SLA”) that provides for service task requests from the first customer to be performed by the service provider, with a level of service to be determined, at least in part, by a first performance parameter of the first SLA, a first performance parameter proportion value of the first SLA and a plurality of predetermined time periods of the first SLA, with an objective of the first SLA being to ensure that the first performance parameter is fulfilled for at least a proportionate number of service task requests of the first customer as specified by the first performance proportion value over the course of each predetermined time period of the first SLA; initially operating under the first SLA for sufficient time so that a plurality of passed time periods of the plurality of predetermined time periods have passed and a current time period has begun; storing a number of service task requests by the first customer under the first SLA for each passed time period; subsequent to the initially-operating step, tracking a number of first SLA missed requests for the current time period, with a first SLA missed request being any service task request of the current time period that does not fulfill the first performance parameter of the first SLA; subsequent to the initially-operating step, receiving a new service task request from the first customer under the first SLA; subsequent to the initially-operating step, fetching the number of service task requests by the first customer under the first SLA for each time period of the plurality of passed time periods; subsequent to the fetching step, determining at least one current-time-period-expected-service-request parameter(s) for the first customer based, at least in part, on the number of service task requests for passed time periods fetched at the fetching step; and subsequent to the determining step, calculating a first risk attribute value for the first customer based, at least in part, upon the least one current-time-period-expected-service-request parameter(s) for the first customer and the number of first SLA missed requests for the current time period tracked at the tracking step.
