Claim 10:
11. A computer system for evaluating change risk in an IT environment, comprising:
a computer with a processor and memory:
an application configured to be executed by the computer and configured to perform the following;
collecting environment state snapshots of configuration parameters in the IT environment;
invoking a manifest of a change on the environment state snapshots to form simulated environment state snapshots; wherein the manifest is an object that specifies the changes that will be performed when modifying the environment;
analyzing the simulated environment state snapshots relative to the environment state snapshots;
deriving a risk score based on the analysis wherein the risk score includes consideration of a drift pattern; wherein configuration parameters representing a sequence of environment components that were consistent having a same value before the change and are not consistent after the change or vice versa are assigned a high risk and configuration parameters that were not consistent before the change and are still not consistent after the change are assigned a low risk selectively performing the change responsive to the risk score.
