8 Steps of the FMEA Process

Failure Mode and Effects Analysis (FMEA) is a method of evaluating a product or process to identify potential risks and areas requiring improvement. In this blog post, we will discuss the 8 steps of the FMEA process.

What is Failure Mode and Effects Analysis (FMEA)?

Failure mode and effects analysis (FMEA) is a systematic approach used to identify potential failures, their effects, and corrective actions to reduce or eliminate the risks associated with those failures. The goal of FMEA is to address potential problems before they cause harm and prevent failures from occurring.

In an FMEA study, a team representing each part of the process is formed. This team comes together to predict where, how and to what extent the system is failing. It then identifies risks that could cause serious damage, preventing the ultimate consequences.

Things to Consider in the FMEA Process

Using FMEA, teams consider how to proactively prevent failures, evaluate processes and improve processes. Therefore, in an FMEA, teams need to review, assess and record a number of factors. These are as follows:

  1. Steps in the process
  2. Failure modes
  3. Reasons for failure
  4. Effects of failure

How is FMEA Implemented?

FEMA is an analysis method that helps identify and mitigate potential errors in a process. It allows businesses to improve product quality, reduce costs and increase customer satisfaction.

The steps of FMEA are as follows:

  1. Define the Process

The first step is to define the inputs, outputs and steps of the process to be analyzed.

  1. Create a Multidisciplinary Team

Everyone involved at different points in the process needs to be involved in the analysis process. Not all of them need to be part of the team for the entire analysis, but they should share their ideas in discussions about the process.

  1. Identify Potential Failure Modes

The team should brainstorm to identify potential failures of the process and take action. The team can try to identify potential problems by generating suggestions or evaluating the risks and scenarios available.

  1. Determine the Severity of the Failure Mode

The next step after identifying potential failure modes would be to determine the severity of each failure. This is done by considering the impact of the failure on financial, operational, organizational and/or influential customers.

  1. Determine the Probability of the Failure Mode Occurring

This step is done taking into account factors such as the complexity of the process, the quality of the people involved and the environment in which the process will be used.

  1. Determining Detectability of Failure Mode

Determining detectability is done using the methods in place to detect defects, such as quality control reviews, customer feedback, etc.

  1. Calculate RPN (Risk Priority Number)

RPN is a numerical value used to prioritize potential failures. RPN is calculated by multiplying severity, probability of occurrence and detectability.

  1. Identify and Implement Corrective Actions

The final step is to identify and implement corrective actions to reduce the RPN of the highest priority failure modes. These actions may include process changes, training or quality control measures.

Benefits of FMEA

  • Encourages teams to work collaboratively.
  • It ensures that the entire process from production to shipment is analyzed in detail.
  • Creates a company culture where ideas are shared and increases employee participation.
  • Supports problem solving and improvement efforts.
