1. A method for analyzing job performance, comprising: at a server computer communicatively connected to a client computer over a network, generating a first performance profile for an entity, wherein said first performance profile for said entity comprises a plurality of measures, wherein each applicable measure of said plurality of measures comprises an entity average determined based on a group of cases that meet a set of criteria specific to said applicable measure, wherein said entity is responsible for said group of cases, and wherein if a case for which said entity is responsible does not meet said set of criteria specific to said applicable measure, it is not included in said group of cases; constructing a second performance profile for a virtual peer with respect to said applicable measure, wherein said constructing step further comprises selecting, from a plurality of peer cases, a composite of cases that also meet said set of criteria specific to said applicable measure, wherein said second performance profile for said virtual peer comprises a peer average determined based on said composite of cases, wherein if a peer case does not meet said set of criteria specific to said applicable measure, it is not included in said composite of cases, wherein said group of cases is a subset of a plurality of cases for which said entity is responsible, wherein said composite of cases is a subset of said plurality of peer cases for which two or more peers of said entity are responsible, and wherein both subsets meet said set of criteria specific to said applicable measure, effectuating a meaningful analysis of said entity's job performance with respect to said applicable measure; and returning results including said first performance profile for said entity and said second performance profile for said virtual peer to said client computer over said network.
