We investigate the structural evolution of the IDV source BL Lac 0716+714 from 10 epochs of global VLBI and VLBA observations. Our study reveals two possible component identification schemes, in which the jet components move either slow or fast. Although the fast motion would fit better to the observed IDV, the quality of our data does not allow a final decision between the slow and the fast picture.
