FMEA: Your Continuous Improvement Crystal Ball

When businesses are looking for areas to improve, the use of a FMEA chart can often work wonders. In some respects it is a crystal ball to help you predict where failures can happen. This is about being proactive with your continuous improvement projects rather than trying to pick up the pieces when something goes wrong!


FMEA stands for Failure Mode and Effects Analysis.

Basically, it gets you to look at individual elements of a process so that you can think about where the process can 'fall over'. It can also be used for products; looking at which components will fail.



The image above (click to enlarge) shows an example FMEA worksheet you could use.

For each failure mode (of each element) that could fail you determine the potential effects and the related root cause(s).

Once this has been done you get to score each failure mode in terms of its:

  • Severity (how much damage it can cause should it happen)
  • Occurrence (how likely it is to happen)
  • Detection (how obvious it is when it does start to happen)

Each of the above is scored from 1 - 10, with 10 being the worst outcome.

All three scores are then multiplied to give you the Risk Priority Number (RPN).

The sheet is then sorted by the RPN value, from high to low.

The items at the top of this list are the ones to go to work on first.


If you haven't used the FMEA approach before it is certainly worth trying out; it may even help you to form your 2014 improvement plans.

Enjoy.

Kaizen improvements need to be specific

Do you find that your Kaizen improvements don't always go to plan? If you do, then you're with the majority! Whilst there is great deal of 'trial and error' there is a simple approach that can help. Available from Amazon Being specific about critical parts of your improvement can uplift your results. So, how do you go about doing this? The most direct route is to be clear about which parts of your improvement are critical. From here you can explain, in detail, what you want for those items. This might take some practice as many of us have become lazy in this regard. We take it for granted that our team 'get us' and will know what they need to do. If you ever feel that something basic is missing from an improvement ask this question: "What does good look like?" The answer should put you back on track.

Where to start with Kaizen, if you just aren't sure

Kaizen is a great word. It is a word that can unleash the potential of both a business and an individual. Kaizen means more than just continuous improvement. It is a word that is linked to: Confidence Growth Exploration Courage Many people I speak to, that are new to improvement projects, aren't sure if they are on the right path when it comes to embracing the spirit of Kaizen. If you are also one of these people then let me share with you a few thoughts that can help you feel at ease about starting and leading change. Start with your concerns A great place to start your improvement life is with anything that isn't right. Getting your concerns out into the open really is the first step for most of us. If you aren't happy with something, raise it. This isn't only a great place to start, but something that you shouldn't give up. Whenever a standard is not being met, or not even defined, get vocal and then do something about it. Start small The intention of Kaizen is

Stimulating Kaizen opportunities - the 'mechanical' way!

I often end up in conversations about how to stimulate Kaizen ideas and opportunities. If you have read my other posts, you will know that I split the improvement journey into two halves. For many people, the initial Kaizen focus is all around fixing things that are wrong / not working properly. Once you get past this point you need something else to focus and motivate you to generate improvement opportunities. The two halves of the Kaizen journey The discussion that I often end up in, is the one around the imagination quandary. People talk to me about not being creative, or not being inspired to come up with improvement ideas. Do you ever feel this way? It seems that there is a popular view that some people are creative and some aren't. Great Kaizen ideas are not just the product of 'creative' people. There are lots of ways that you can generate improvement ideas without having to sit on a mountain top cross legged waiting for inspiration. Finding a 'mechanical' w
