A computer system for determining whether or not a tool for deploying a software patch should be invoked is provided. The system may include a receiver that receives information regarding patch deployment over a first pre-determined amount of time. The system may include a processor configured to determine, based on the historical information, a patch deployment index. The patch deployment index may characterize patch deployment as a number of patches deployed per unit time. The receiver may receive historical information regarding patch deployment over a second amount of time. The processor may use the historical information regarding patch deployment of the second pre-determined amount of time to determine a second patch deployment index. The processor may compare the first deployment to the second patch deployment index. When the difference between the second index and the first index is greater than a pre-determined threshold, the processor may invoke the tool.
