Management Decisions against Functional Violations of Web Services?

The success of Service Oriented Systems mainly depends on the extent to which the user’s functional requirements are satisfied. The execution of Web services needs to be monitored to know the performance during its operational period. Also it is important to take management decisions to control or modify its operations within the operational environment. In this paper, ten real world web services are monitored to gain knowledge about the deviation from the asserted guarantees by the provider of the Web service. Also appropriate management decisions to update the service to correct the deviations are proposed to reach the assertions mutually agreed by the signing parties of the Web service.
