You might want to assess that mate! |
So whether you are introducing a new product or new piece of kit, implementing new ways of working, improvement projects or just want to assess your existing processes for potential risks we are going to share our tool of choice to allow you to do this.
Any Risk Assessment needs to follow a structured approach, involve and engage staff and in true Lean Sigma style be data driven. The Failure Modes & Effects Analysis (FMEA) tool ticks all these boxes. It is a systematic method for Identifying, Analysing, Prioritising and Documenting potential failure modes, their effects on a system, product or process performance and the possible causes of failure.
Structured Approach is Key |
- The Likelihood of Failure
- The Severity of the impact of the Failure
- The levels of Detection in place
How can something fail?
What is the effect of this?
What could cause the
failure?
What control measures prevent it
FMEA Template |
So how do you go about running an FMEA study:
- Define the scope of the FMEA (what it is and importantly is NOT)
- Agree scoring regime (see example below)
- Analyse and list Failure Modes for each area/step
- Understand the effect of failure
- Understand what detection/controls are in place
- Calculate RPN (Ranked Priority Number)
- Review RPNs and assign cut-off and action limits
- Create Action Plan
- Manage Action Plan
Suggested Scoring Regime |
Identify potential sources of risk |
You can use some of the basic Lean Sigma tools such as Process Maps, IPO diagrams and Cause & Effect diagrams (Fishbone diagrams) to identify potential failures or risks. You then simply plug these risks into the FMEA tool to help prioritise the areas to focus your actions on.
We have used this tool on manufacturing processes, when introducing new products into a facility and when assessing the impact of changing ways of working and in each case it has successfully reduced the risks to implementation.
So give it a try next time you are planning a change.
