Abstract: Example issue processing systems and methods are described. In one implementation, a method identifies an issue and accesses rules related to resolving the issue. The method also accesses data associated with previous issue resolutions. The identified issue is analyzed based on the rules and data associated with previous issue resolutions. Based on the analysis, the method determines a first activity to perform and identifies the results of performing the first activity. If the first activity did not resolve the issue, the method further analyzes the issue based on the rules, the data associated with previous issue resolutions, and the results of performing the first activity. Based on this further analysis, the method determines a second activity to perform in an attempt to resolve the issue.
