Risk mitigation for computer system change requests
View Patent ↗Implementation of change requests involves risk for computer systems. Methods of mitigating such risk, and apparatus to perform the methods, include comparing levels of risk of risk factors of a change request to corresponding risk factors of one or more prior change requests, and suggesting alternative factor values to lower an expected level of risk.
1. A method of mitigating risk of change implementation in a computer system, comprising:
assessing a level of risk of a risk factor of an original change request for the computer system by a processor;
comparing, by the processor, the level of risk of the risk factor of the original change request to a level of risk of a corresponding risk factor of at least one prior change request having at least one risk factor corresponding to a risk factor of the original change request, wherein the at least one prior change request is contained in a non-transitory storage media in communication with the processor;
modifying the original change request if the level of risk of the risk factor of the original change request is greater than the level of risk of the corresponding risk factor of any of the at least one prior change requests; and
implementing the modified change request on the computer system.
2. The method of claim 1 , wherein the original change request comprises a request to add, remove or modify at least one software application, hardware component or device of the computer system.
3. The method of claim 1 , further comprising:
assessing a level of risk of a second risk factor of the original change request for the computer system; and
applying logic specific to the second risk factor to suggest a modification to the second risk factor of the original change request without comparing to a risk factor of the at least one prior change request.
4. The method of claim 1 , further comprising:
identifying the at least one prior change request having at least one risk factor corresponding to a risk factor of the original change request from a database of historical change requests.
5. The method of claim 4 , wherein identifying the at least one prior change request comprises at least one act selected from the group consisting of applying an adaptive similarity analysis to the database of historical change requests, and identifying change requests from the database of historical change requests having a same category as the original change request.
6. The method of claim 1 , further comprising:
assessing a level of risk of each risk factor of an original change request for the computer system;
comparing the level of risk of each risk factor of a first set of risk factors of the original change request to a level of risk of the corresponding risk factors of at least one prior change request having at least one risk factor corresponding to a risk factor of the original change request;
modifying the original change request if the level of risk of any risk factor of the first set of risk factors is greater than the level of risk of the corresponding risk factor of any of the at least one prior change requests; and
for a second set of risk factors of the original change request, applying logic specific to each risk factor of the second set of risk factors to suggest a modification to the original change request;
wherein the first set of risk factors and the second set of risk factors are mutually exclusive.
