  • Your career planning

First 30 minutes of consultation for free, every additional 1 hour 10 USD.

What is FMEA?

F M E A is one of tools, that helps us understand potential failures in the processes, failure causes, and their effects. By understanding this, we can focus on reducing all these not needed influences.

F M E A is an acronym, that stands for – Failure Mode and Effect Analysis. There are different F M E A types: Functional, Design, and Process F M E A.

We use team experiences with similar products, processes, or common-sense logic, to estimate failure probability. There is a worksheet used to record these potential failures, and analyze reliability under the video.

Rules during FMEA

Here are some rules to follow when creating F M EA:

  • Identify process of one product, you would like to review. Try to address entire process under your control. Divide it if it is too wide. You can use value stream map, or process map for process identification.
  • If you are running improvement project, address processes within project scope. Process mapping can help you with identification. Do not solve whole facility at once.
  • Plan this activity in advance. People must count with it in their schedule.
  • Work as a team. Invite at least one person from assessed process. As well as colleagues from different departments
  • Visit, and observe assessed process. Walk to see is key to reveal possible failures.
  • Do not hesitate to ask questions, while observing.

How to fill FMEA scoring table?

It is little boring, but you will create and fill table. Write down each process step. There can be several potential failures in each step. Personal observation will help you not skipping anything.

Occurrence defines, how likely failure will occur. Severity ranks failure effect. Detection ranks how likely failure will be noticed. Rank all 3 cathegories by 1 to 10. 1 for the lowest, and number 10 for the most negative impact.

Work in teams to rate probability severity and detection number for each potential failure. Risk preference number is calculated by multiplying all 3 numbers together.

FMEA as a living document

F M E A is a living document. It is key to review it on regular bases. You can start with yearly reviews. It is good to have notes written next to each number for these future reviews. Simply explain, why you have chosen such a number, and people reviewing F M E A will be thankful for it.

Steps performing FMEA

How to address risks?

Now it is time to address and try to reduce the biggest risks based on final RPN.

Use this decision table for action and measures determination. Start addressing potential failures with high risks, first. Then medium risks. Briefly review also acceptable once just to be sure not missing any potential troublemaker.

FMEA tires exchange example

Here is F M E A example on tires exchange. Out of 3 potential failures one have high R P N, one is with medium and one acceptable risk preference number. Do not hesitate to simply describe each potential failure.

Filled FMEA example – add notes to each of team decision

Actions, also called counter-measures, must be bullet-proof to decrease risk to minimum level. Like torque air-gun usage, in the case of bolts not tight properly potential failure.

Now it is time to implement described actions. Idenify owners, set a due dates. Meet regularly to check out progress on implementation activities.
