Abstract
A method for generating an electronic quality record of a manufacturing operation that may involve generating inputs from a plurality of information sources located within a manufacturing environment. The plurality of information sources may provide information pertaining to at least a tool being used, an individual using the tool, and an operation that the tool is being used by the individual to perform. A locating system may be used that is in communication with the plurality of information sources to monitor a location and an operation of the tool. A processor may be in communication with the locating system to receive the generated inputs and to generate an electronic record upon completion of the operation that the tool is being used by the individual to perform. The electronic record may identify that the operation has been performed by the individual using the tool in accordance with a predefined standard.
