The acronym DFMEA stands for "Design Failure Mode Effects Analysis". DFMEA is an extension of Failure Mode and Effects Analysis which attempts to estimate the frequency and severity of each failure mode.

PFMEA is also called potential failure mode effects analysis. The purpose of PFMEA analysis is to take actions to eliminate or reduce failures, starting with the high priority ones.

Failure mode effects analysis (FMEA) is used to identify the ways in which a system will fail, the likelihood of each failure mode, and what will happen in the event of each failure. It is used in both product design, to improve intrinsic availability and reliability, and in operations management, to improve process design.

The FMEA is a risk assessment tool that helps systematically define where potential points of failure are located, help define the critical nature of the problems and logically layout the plans to resolve them.

Equipment Failure Mode and Effect Analysis (EFMEA) is a systematic technique used to identify and prioritize potential failure modes of equipment, understand their causes and effects, and develop preventive actions to mitigate the risks associated with those failures. It is commonly used in industries such as manufacturing, aviation, and healthcare to improve equipment reliability, maintenance strategies, and overall system performance.
