A method of generating feedback for a container load process includes: during a load process for a container at a load bay, controlling a sensor assembly disposed at the load bay to capture sensor data depicting an interior of the container; at a computing device connected to the sensor assembly, detecting, based on the sensor data, a wall of items placed in the container interior; determining, at the computing device from the sensor data: (i) a boundary attribute of the detected wall, and (ii) a composition attribute of the detected wall; comparing, at the computing device, (i) the boundary attribute to a boundary criterion, and (ii) the composition attribute to a composition criterion; and responsive to at least one of the boundary attribute not meeting the boundary criterion, or the composition attribute not meeting the composition attribute, generating an alert for transmission to a client computing device.
