This system of release authorization enforces, via software, compliance to Configuration Management principles. When a process goes unmonitored, unmeasured and uncorrected, very large and unpredictable swings in quality and quantity will occur. Engineering Data Collection and Analysis occurs every time parts are processed through an operation in the factory. Manufacturing Specifications Enforcement Specifications are enforced in the sense that the routing or traveler calls out the sequence of operations that are required to manufacture a product. Deviation from that sequence is not possible without a password that allows deviations.
Travelers have an optional and alternate steps capability.
Once past the optional or alternate step, the operator can not go back and choose the optional step without knowing the password. The rework is recorded with the history of the device or lot. On-line Documentation Manufacturing specifications are also enforced in that technical specifications are put on screen whenever a device or lot is checked into an operation. The user has the option of printing the specifications if necessary to take back to their work station. They also have the option of reviewing any documentation associated with the operation such as supporting documents and drawings.
