Abstract

An electronic control tag system was developed by a defense contractor for the hardware that flowed through its production system. Advantages of the electronic inspection system included avoiding the problems caused by lost paper documents; improved documentation control over a system using thousands of pieces of paper for some production items; and reducing document storage space. Early steps in developing the new system involved obtaining management support; helping individuals overcome the inertia of staying with the old system; and agreeing to convert only some of documentation to the new system in this first stage. Then, the current inspection process was mapped with a flow diagram, and information systems personnel used this and other data to develop computer screens for the electronic control tags. The new system was to have links to existing electronic systems that managed shop floor control, nonconformance reporting, and configuration tracking. But it was vital that these links be made without changing the other systems. System development also included creation of lock-outs based on user identification codes. The new system received validation and verification testing from personnel of units that would be using the electronic control tags. The development process also included keeping customers aware of this system change and training personnel in its use. Upon implementation, there still is some paper in the inspection system. Traveler documents and nonconforming material identification tags still are in use.
