For this method to be applicable, you have to find a control group that shows a trend that’s parallel to your treatment group for the metric of interest, prior to any treatment being applied. Then, after treatment happens, you assume the break in the parallel trend is only due to the treatment itself. This is summed up in the above diagram.
