Design FMEA software, built for engineers

What is a DFMEA?

A Design FMEA (DFMEA) is a structured method for analyzing how a product design could fail to meet its intended function or requirements. It is performed early in development — while the design can still be changed at low cost — and is owned by the design team. For each potential failure mode, the team identifies the effects, the causes rooted in the design, and the prevention and detection controls in place, then rates the risk to decide where to act first.

Under the AIAG-VDA FMEA handbook, a DFMEA follows a seven-step method: planning and preparation, structure analysis, function analysis, failure analysis, risk analysis, optimization, and documentation of results. DFMEA software like QSA Hub keeps these steps connected on one canvas instead of scattered across spreadsheet tabs.

How QSA Hub builds a Design FMEA

QSA Hub models the DFMEA the way the standard describes it — as a connected chain rather than rows in a grid:

1. •Structure analysis. Lay out the system, subsystems, and components as a structure tree so the scope of the analysis is explicit.
2. •Function analysis. Attach the functions and requirements each element must deliver, linking them across levels.
3. •Failure analysis. Build the failure chain — failure effects, failure modes, and design causes — connected to the functions they break.
4. •Risk analysis. Enter Severity, Occurrence, and Detection; QSA Hub returns the Action Priority (High/Medium/Low) directly from the AIAG-VDA tables.
5. •Optimization. Record improvement actions and re-rate, keeping the original ratings so risk reduction stays traceable.
6. •Export. Export a fully formatted Design FMEA to the standard Excel layout your customer or process expects.

Who uses DFMEA software

DFMEA is used by hardware and software design engineers across automotive and manufacturing, often as part of an APQP or ISO 26262 workflow. Because the analysis is cross-functional, design, quality, and safety engineers typically contribute to the same DFMEA. QSA Hub is built for that audience: a focused FMEA tool, not a generic spreadsheet, that keeps every Design FMEA structured and consistent with the AIAG-VDA standard.

Once a design is stable, the DFMEA feeds the Process FMEA — design risks and special characteristics flow down as inputs to the PFMEA. QSA Hub supports both DFMEA and PFMEA on the same structured, AIAG-VDA-aligned canvas, so the two analyses stay consistent. See DFMEA vs PFMEA for how the two differ, and how Action Priority works.
