A VDA 6.3 process audit scores each question from 10 to 0 and classifies the result A, B or C, but downgrading rules and star questions can override a good percentage. Suppliers should confirm the edition and prepare element by element.
A PFMEA built on the AIAG and VDA handbook follows seven steps, rates risk with high, medium or low action priority instead of RPN, and only works if its prevention and detection controls are carried into the control plan.
Just in time supply still suits robust, short lead time parts, but the chip shortage showed the cost of low stock and short commitments. Protect single-source, long lead time parts with defined buffers and keep lean flow elsewhere.
PPAP proves a production process can meet the design record at rate. Keep all 18 elements on file whatever the submission level, and check each customer's own requirements before any design, process or tooling change.
A long shift log can still omit the information the next team needs. Manufacturers should organise handover around equipment state, product status and pending decisions, with time for the incoming team to cross-check understanding.
A list of trained names can overstate workforce readiness. A useful skills matrix connects tasks, demonstrated competence and shift coverage, then identifies the operating decisions that depend on scarce capability.
A capable mentor can still struggle when development work competes with an unaltered production target. Manufacturers should plan suitable tasks, supervision and review time as part of the operating arrangement supporting an apprentice.
An energy intensity figure can change because of product mix, idle demand or quality losses. Plants need a defined boundary and production context before using energy per accepted part to compare performance or justify investment.
Changing the heat source can affect process behaviour as well as energy demand. Investment teams should assess product requirements, utility capacity and the transition plan before choosing an electrification route for a manufacturing process.
A replacement compressor can leave avoidable demand untouched. Manufacturers should establish operating patterns, pressure requirements and maintenance conditions before deciding which equipment investment will improve the complete compressed air system.
