Abstract: Method and apparatus for evaluating user movement in a fulfillment center. A plurality of sub-tasks for performing a fulfillment operation are determined. Embodiments retrieve a training set of motion data that includes a plurality of training motion data samples, each specifying motion data over a respective window of time, and train a first data model to classify instances of motion data into portions, based on the plurality of sub-tasks. At least one data model is trained to assess performance of the fulfillment operation, using the training set of motion data. An instance of motion data describing motion performed during the fulfillment operation is received, the instance of motion data is divided into a plurality of portions, using the first data model, and a measure of quality is generated, by analyzing the plurality of portions of the instance of motion data using the trained at least one data model.
