1. A method for optimizing workflow in an assembly line, the method comprising:
receiving image data tracking assembly of a target object through a manufacturing process;
identifying a subset of image data corresponding to a step in the manufacturing process;
analyzing the subset of the image data to identify data associated with an operator performing the step in the manufacturing process on the target object;
analyzing the subset of the image data to identify the target object upon which the operator is performing the step;
determining that the target object is out of specification by:
comparing the data associated with the operator performing the step in the manufacturing process on the target object to nominal data associated with a nominal operator performing the step in the manufacturing process, and
comparing the target object at the step of the manufacturing process to a nominal target object; and
based on the determining, adjusting subsequent steps in the manufacturing process to bring the target object into specification.
