Brainstorm Error Proofing Mechanism
Make visible/obvious if incorrect part
- Color code - match part to product
- Visible at numerous operations and pack
- Position of part as moves down line
- Visual aid/picture posted with correct part present and highlighted
Redefine process
- Assemble early in process
- Successive check
- Rearrange multiple write-up to separate assembly of like parts
Monitor part supply
- Only supply parts needed for that model
Sensors
- Photoelectric eyes to detect, lock out until corrected
- Limit switch to detect, lock out until corrected
Modify/design fixture
- Unable to assemble incorrect part
Modify design
- Eliminate part
- Prevent assembly of incorrect part
