1. A method comprising:
selecting, by a processing system in a telecommunication service provider network, a study group, wherein the study group comprises at least a first network element of the telecommunication service provider network;
selecting, by the processing system, a control group, wherein the control group comprises a second network element of the telecommunication service provider network;
identifying, by the processing system, a time at which a change is deployed at the first network element;
computing, by the processing system, a first time-series based on a first set of values for key performance indicators of the study group, wherein the first set of values is measured prior to the time at which the change is deployed at the first network element;
computing, by the processing system, a second time-series based on a second set of values for the key performance indicators of the study group, wherein the second set of values is measured subsequent to the time at which the change is deployed at the first network element;
computing, by the processing system, a third time-series based on a third set of values for key performance indicators of the control group, wherein the third set of values is measured prior to the time at which the change is deployed at the first network element;
computing, by the processing system, a fourth time-series based on a fourth set of values for the key performance indicators of the control group, wherein the fourth set of values is measured subsequent to the time at which the change is deployed at the first network element;
detecting, by the processing system, an impact of the change on a performance of the telecommunication service provider network by comparing the first time-series, the second time-series, the third-time series, and the fourth time-series; and
initiating, by the processing system, a remedial action when the impact comprises a degradation to the performance.
