Both Risk Register and FMEA are Risk Management Tool that are used by many organisations worldwide to mitigate the risk, but surely they have got their own different purpose, advantages and disadvantages.
Risk Register
In this methodology, we try to identify and capture the potential risks involved in a project or in an organisation. These potential risk are updated in Risk register and are followed and tracked to keep a basic overview of the condition or status. Basically Risk Register has got 4 parts: Identify, Analyse, Plan and Action. Also Components of each stage can be understood from the pic attached below.
Identity: This involves Risk Identification and its description along with potential causes.
Analyse: Analysis of Risk in terms of Likelihood, Impact and Proximity.
Plan: Defining risk management plan along with fixed ownership.
Action: In this we monitor and update the status of Risk over time.
Failure Mode Effect Analysis
FMEA is a tool used by organizations for evaluation of failure modes in a product, process, system using a very systematic approach of focusing and prioritising on the identified failure modes by identifying the severity, likelihood/occurrence and detection of the mode. By analysing above we calculate Risk Priority Number(RPN) and define action plan for elimination of failure mode. Higher the RPN number higher is the priority for elimination of failure mode. FMEA has got 7 parts: Failure mode identification, Failure mode effect, Severity, Occurrence, Detection, RPN Calculation and Action. These can be understood properly by the pics below:
Advantages / Disadvantages /Use Cases
1. Risk Register has a Broader Scope and deals with the risk involved in a project or organization.
FMEA is more Specific and Systematic in analysis of Failure Modes in a product, process, design, etc.
2. Risk Register is all about identifying and managing risk and its impact on project objectives.
FMEA focuses on identification of failure modes and its impact of the performance and deliverables of a system.
3. Risk Register is used in Project Management centrally controlled and helps in taking predefined decisions.
FMEA on the other hand is mostly deployed in engineering, designing, manufacturing in detailed failure mode analysis.
4. Risk Register is for risk which may occur in future and has got action plan to be taken in future to mitigate the risk.
While FMEA is identification of failure mode which may occur in future and taking action in present to eliminate such cases in future.
Use Case Example:
Risk Register: We will use risk register when we are planning to setup a new plant. We will identify potential risk involved like Land Allocation, Certification, Pollution NOC, Local Demography, chances of flooding in rains, Seismic zone, local politicians, etc. We will make a well-defined action plan along with concerned owner for mitigation of the risk.
FMEA: We will use FMEA whenever we are designing a new product or defining a new process. In this we will define the failure modes like lower specs, non-functional part, Early Failure, not meeting customer requirements, imbalanced process, breakdown of machine, etc. Actions will be taken immediately to eliminate these cases and chances of occurrence in future.
Conclusion:
Risk Register and FMEA are both great tools for Risk Management but both have different applicability, advantages and disadvantages. Risk Register being more broader and general towards complete organization while FMEA focusses on analysis and elimination of failure modes in a particular product or process.
