1. A data processing system for engagement review of multiple outsourcing offerings, the data processing system comprising: a memory comprising: an upper tier metric set for multiple outsourcing offerings comprising a first outsourcing offering and a different second outsourcing offering; a first engagement extended metric set for the first outsourcing offering comprising: the upper tier metric set; and a first engagement extension comprising first outsourcing offering specific metrics specific to the first outsourcing offering, first engagement extended metric set threshold values and first engagement extended metric set calculations for the first outsourcing offering specific metrics; a second engagement extended metric set for the second outsourcing offering comprising: the upper tier metric set; and a second engagement extension comprising second outsourcing offering specific metrics specific to the second outsourcing offering, second engagement extended metric set threshold values and second engagement extended metric set calculations for the second outsourcing offering specific metrics; a database comprising engagement operations data from engagement outsourcing operation sites; a processor configured to execute a metric processing program comprising processor executable instructions that when executed cause the processor to: apply the first engagement extended metric set calculations to the engagement operations data to calculate first processed metrics values for first processed metrics; compare the first processed metrics values to the first engagement extended metric set threshold value to generate first processed metrics results for the first outsourcing offering; apply the second engagement extended metric set calculations to the engagement operations data to calculate second processed metrics values for second processed metrics; and compare the second processed metrics values to the second engagement extended metric set threshold value to generate second processed metrics results for the second outsourcing offering; where the processor is further configured to generate a user interface comprising a metric reporting interface for reporting the first and second processed metrics results, where the metric reporting interface comprises: a rolled-up summary of the first processed metrics results; or a rolled-up summary of the second processed metrics results; or a drill-down link to increasingly detailed reports of the first processed metrics results; or a drill-down link to increasingly detailed reports of the second processed metrics results; or any combination thereof, and wherein the processor is further configured to establish an access hierarchy comprising a first access entry authorizing access for a first login to baseline metrics, and a second access entry authorizing access to a first subset of the baseline metrics.
