Process FMEA
Aegix structures the PFMEA as process item, process steps by operation number and work elements, links each step to the characteristics it has to hold, and shows where the analysis still has gaps.
Process item, process steps by operation number, and the control plan characteristics the selected step has to hold.
The method
Aegix follows the AIAG & VDA steps for a process analysis. Each step starts from what the previous one produced, so nothing is entered twice.
Process item, process steps by operation number, and the work elements of each step.
What each step and work element has to achieve, with the characteristics it has to hold.
The failure mode at the step, its effect on the product and its cause at the work element.
Severity, occurrence and detection, and the Action Priority they give.
Prevention and detection actions with an owner and a due date, then the new ratings.
Work elements
Each process step fans out to its work elements, tagged by the category they are analysed under. A work element with no function or failure mode stands out, so a gap shows before the review, not during it.
The operator and the skills the step depends on.
Equipment, tools and fixtures.
Parts and materials entering the step.
The work instruction and the sequence.
Conditions around the step, such as temperature and cleanliness.
Gauges and checks that confirm the result.
The process structure as a diagram. The work element outlined in red has no function and no failure mode against it yet.
Control plan
Product and process characteristics sit on the process function that has to hold them, so a failure mode is analysed against the characteristic it puts at risk.
The PFMEA and the control plan describe the same line.
Human in the loop
From your process documents, AI agents draft the functions and the failure modes. Each draft waits for an engineer to accept, change or reject it.
Questions
A Process FMEA (PFMEA) is a failure mode and effects analysis of a manufacturing or assembly process. It looks at how the process can fail, what the effects on the product would be and what could cause them, so the risks are reduced before production. The AIAG & VDA handbook describes it in seven steps.
Aegix structures the PFMEA as process item, process steps by operation number and work elements by category, links each step to the characteristics it has to hold, shows where the analysis still has gaps, and drafts functions and failure modes for your engineers to review.
The categories a process step is analysed under: man, machine, material and method, often extended with environment and measurement. Aegix tags every work element with its category.
The AIAG & VDA FMEA method, with severity, occurrence and detection ratings and Action Priority. Templates are configurable for other terminology, rating scales or worksheet layouts.
