Process Flow Diagram Editor

The Process Flow Diagram editor uses standard AIAG APQP symbols: rectangles for operations, diamonds for decision/inspection points, triangles for storage, arrows for material flow, and rounded rectangles for transport. Drag and drop process steps onto the canvas, connect them with flow arrows, and assign operation numbers.

Operation numbering follows automotive convention with configurable increments (10, 20, 30...) to leave gaps for future inserted steps. Each process step captures: operation number, operation name, machine/device, key input characteristics with CC/SC classification, key output characteristics with CC/SC classification, and operator requirements.

Process steps defined in the PFD automatically populate your PFMEA structure analysis (Step 2 of the AIAG-VDA 7-step process). The synchronization is bidirectional:

- Add a process step in the PFD → it appears in the PFMEA as a new row category - Rename an operation in the PFD → the PFMEA updates automatically - Delete a process step → the system warns about associated failure modes before removing

Visual indicators on each PFD step show the number of associated failure modes and their risk levels: ‘Op 30: Assembly — 7 failure modes, 2 High AP’. This lets your team see risk density at the process flow level before diving into the detailed FMEA.
