Error proofing refers to preventing a process from resulting in defects by stopping mistakes at the source, rather than down the line.
Another word for error proofing is poka-yoke (which is Japanese for avoiding inadvertent errors). Poka-yoke design is often used to avoid human error by either warning operators when they are about to make a mistake or preventing them from making a mistake at all. Poka-yoke design makes it virtually impossible for an operator to complete an action incorrectly.
Preventing mistakes at the source can significantly improve productivity by keeping mistakes from becoming bigger problems downstream.
Error-proofing takes quality control to the next level by checking for mistakes and defects before those defects can proceed to the next stage of production. Preventing defects from proceeding from one stage of production to the next avoids wasted time and resources spent working on defective parts.
In manual processes, such as bin picking, visual warnings clearly indicate to operators when their actions are correct or incorrect using colored and/or animated lights. Light-guided assembly is an excellent example of using visual indication for error-proofing.
Meanwhile, in more automated processes, error proofing solutions like sensors and vision systems can be used to ensure poblems are corrected before a process can proceed.
