Cause & Effect Analysis:
Effective health and safety management is not common sense but is based on a common understanding of risks and how to control them brought about through good management. If a firm can dictate, in advance, what actions it should take to prevent accidents, then it can measure how well these predetermined actions are executed. Risk assessment is a method that is predictive and can indicate the potential for loss. With this knowledge, an organization is then able to set up the necessary management controls to prevent these risks resulting in losses such as injuries, property damage.
Failure Mode and Effects Analysis (FMEA): is product recalls resulting from poorly designed products and/or processes.
Failure Mode and Effects Analysis, or FMEA, is a methodology aimed at allowing organizations to anticipate failure during the design stage by identifying all of the possible failures in a design or manufacturing process.
Here’s an overview of the 10 steps to a Process FMEA.
1. Review the process
- Use a process flowchart to identify each process component.
- List each process component in the FMEA table.
- If it starts feeling like the scope is too big, it probably is. This is a good time to break the Process Failure Mode and Effects Analysis into more manageable chunks.
2. Brainstorm potential failure modes
- Review existing documentation and data for clues about all of the ways each component can fail.
- The list should be exhaustive – it can be paired down and items can be combined after this initial list is generated.
- There will likely be several potential failures for each component.
3. List the potential effects of each failure
- The effect is the impact the failure has on the end product or on subsequent steps in the process.
- There will likely be more than one effect for each failure.
4. Assign Severity rankings
- Based on the severity of the consequences of failure.
5. Assign Occurrence rankings
- Rate the severity of each effect using customized ranking scales as a guide.
6. Assign Detection rankings
- The chances o failure will be detected prior to it occurring.
7. Calculate the RPN: Severity × Occurrence × Detection
8. Develop the action plan
- Decide which failures will be worked on based on the Risk Priority Numbers. Focus on the highest RPNs.
- Define who will do what by when.
9. Take action
- Implement the improvements identified by your Process Failure Mode and Effects Analysis team.
10. Calculate the resulting RPN
- Re-evaluate each of the potential failures once improvements have been made and determine the impact of the improvements.
