Methods for error proofing

Verfahren zum Ermitteln von Fehlern

Procédé pour l'évaluation d'erreurs

Abstract

Methods for error proofing (20), which also improve material, or information, flow through a process, are described. In one embodiment, the method includes the steps of identifying a process responsible for at least one error, process mapping (14) the identified process, identifying (16) at least one step in the identified process at which scrap and/or nonconformance occurred, and razing (18) the identified process. The step of razing, in the one embodiment, is performed by determining whether a plurality of errors throughout the identified process occurs, and if a plurality of errors are identified throughout the identified process, determining whether a different process can be substituted for the identified process, and if the different process can be substituted for the identified process, then substituting the different process for the identified process. If the different process cannot be substituted for the identified process, then the process further includes performing the steps of determining whether the identified step (52-70) can be eliminated, and if the step can be eliminated, then eliminating the step. If the step cannot be eliminated, then the process further includes performing the steps of determining whether the identified step can be simplified, and if the step can be simplified, then simplifying the step. After razing the process, the razed process is error proofed, and then the error proofed razed process is analyzed to verify that scrap and nonconformance has been reduced.
