1. A method of performing at least one diagnostic test in an integrated support platform having a plurality of services, the method comprising: building at least one or more knowledge model for respective of the plurality of services in the integrated support platform by determining one or more components related to the plurality of services, wherein building the at least one knowledge model comprises: determining one or more possible failures of respective components of the one or more components and at least one associated symptom to identify the one or more possible failures; constructing a framework for one or more diagnostics, that are associated to the one or more possible failures by creating at least one execution plan based on a most efficient path for determining a possible failure of the one or more possible failures, wherein the most efficient path for determining the possible failure of the one or more possible failures comprises a route defined though a process that comprises computing a historical result for a specific problem and associated diagnostics of the one or more of the diagnostics associated with the specific problem to determine a most used of the associated diagnostics of the one or more diagnostics for resolving the possible failure, wherein the most used of the associated diagnostics of the one or more diagnostics is prioritized based on a resolution index assigned to the most used of the associated diagnostics of the one or more diagnostics; and performing the at least one diagnostic test resolving one or more failures of respective components by using the framework based on the built knowledge model for the plurality of services.
