Reviewed by [Christian Espinosa, Founder, Blue Goat Cyber](/authors/christian-espinosa) Last reviewed May 5, 2026 ## Definition DFMEA feeds [design controls](/terms/design-controls) and the [risk management file](/terms/risk-management-file). PFMEA feeds [process validation](/terms/process-validation), control plans, and [supplier controls](/terms/supplier-controls). Both should be living documents updated as the design and process mature. What the regulation says Design [Failure Mode and Effects Analysis](/terms/fmea) (DFMEA) is a risk management tool applied during design and development, as outlined in [ISO 14971](/terms/iso-14971):2019, to identify potential failure modes of a device. Process Failure Mode and Effects Analysis (PFMEA) focuses on manufacturing or service processes, identifying potential process failures and their effects, contributing to [process validation](/terms/process-validation) as indicated by FDA 21 CFR 820.70(a) for [production and process controls](/terms/production-process-controls). ## What this means in practice Confusing the two - or treating PFMEA as a one-time deliverable - is a recurring quality finding during [PAI](/terms/pai) and [Notified Body](/terms/notified-body) audits. ## Examples - A DFMEA for an insulin pump identifies a potential failure mode where the pump delivers an incorrect dosage due to software error, leading to a design control requirement for redundant software checks. - A PFMEA for the assembly of a surgical instrument identifies a potential failure mode where a critical component is incorrectly seated, leading to the implementation of automated vision inspection in the manufacturing process. - During the development of a new diagnostic imaging device, the DFMEA identifies a material incompatibility risk; this prompts a specific material verification step to be included in the PFMEA for the device’s manufacturing. Common pitfalls - • Confusing the scope of DFMEA with PFMEA can lead to critical risks being overlooked in either product design or manufacturing processes. - • Treating PFMEA as a static document, rather than a living one, results in an inability to adapt to manufacturing changes and continuous improvement efforts. - • Failing to link DFMEA outputs to design controls means that product risks identified are not adequately mitigated through design. - • Neglecting to integrate PFMEA outputs into process validation and control plans can lead to manufacturing inconsistencies and product defects. - • Ignoring supplier process risks in the PFMEA can introduce vulnerabilities into the supply chain that impact product quality and safety. ## Frequently asked questions When should a DFMEA be initiated? A DFMEA should be initiated early in the design phase, typically during concept development, and continuously updated throughout the design lifecycle as new information becomes available and changes occur. What is the primary output of a PFMEA?
