Direct answer

The process-diagram trap is listing every label without showing how stages connect, or using line-graph vocabulary on a manufacturing cycle. Examiners want an overview from raw material to finished product (or full loop), then body paragraphs in logical order with accurate sequencing verbs. Reversed stages or a missing end state caps Task Achievement.
