Idea Summary
Have access to the working instructions when executing a WIP job step by step

Use Case
This use case addresses the inefficiencies and errors associated with traditional paper-based Work-In-Progress (WIP) execution on the manufacturing shop floor. Implementing an APEX with MES with Bill of Materials (BOM) integration aims to digitize and streamline the entire production process, eliminating the need for physical documents and providing real-time visibility into ongoing operations.

Preferred Solution (Optional)
1 - The APEX retrieves and displays the electronic work instructions for the first/next operation. It clearly indicates the required mBOM version and, if applicable, the software version for this specific order and product revision. 

1. The APEX MES retrieves and displays the electronic work instructions for the first/next operation. It clearly indicates the required mBOM version and, if applicable, the software version for this specific order and product revision.
2. The Production Operator logs into their assigned APEX MES terminal/tablet. They select or scan the Production Order they will be working on.
3. The operator scans the materials/components required for the current step. 
4. The APEX MES Verification, where  APEX MES validates the scanned materials against the specified mBOM version. It checks for:
   Correct part number.
   Correct revision.
   Approved lot/serial number.
   Expiry date (if applicable).
   Any specific usage rules (e.g., FIFO - First-In, First-Out).
5. If the process requires software/firmware, the APEX MES either instructs the operator to select the correct version or automatically triggers the download of the exact version specified in the PLM/MES to the relevant equipment/product. It verifies successful loading.
6. The operator follows the on-screen instructions, performing the manufacturing steps. The APEX MES may collect data directly from integrated equipment (e.g., torque values, temperatures) or prompt the operator for manual input.
7. At designated points, the APEX MES prompts for quality checks. The Quality Inspector or Operator performs these checks and records the results (pass/fail, measurements) directly into the MES.
8. Once a step is completed, the operator confirms this in the APEX MES. The APEX MES updates the WIP status for that unit/batch in real-time.
9. Upon completing the final step for the production order, the operator marks it as complete in the APEX MES.
10. The APEX MES automatically updates the ERP system with the production yield, scrap, and material consumption.
