Guide: Risk Analysis
- Last Updated:
Risk Analysis is an essential proactive measure in Lean Six Sigma, aiming to identify, assess, and control potential risks to business processes. As a preliminary step in new projects, it safeguards against introducing new problems while managing existing ones.
This structured approach is important in a data-driven environment, where unaddressed risks could undermine efforts to eliminate waste and reduce variation. By anticipating problems before they arise, Risk Analysis acts as a strategic tool for informed decision-making, resource allocation, and maintaining continuous improvement within an organization.

What is Risk Analysis?
Risk Analysis is a structured approach for identifying, assessing, and controlling potential risks that can affect the efficiency and effectiveness of business processes. Risk analysis can also be used a the start of a new Lean Six Sigma project as a way of identifying potential risks to project success. Risk analysis is an integral part of process improvement and management, ensuring that any changes made to enhance a process do not add new issues and that existing risks are identified and managed.
In the context of Lean Six Sigma, Risk analysis is key because the methodology is data-driven and focused on elimating waste and reducing variation. Any unaddressed risks could add variability, cause defects, or create waste within the process, which will directly counteract the Lean Six Sigma project objectives.
The Importance of Risk Analysis
Risk Analysis in Continuos Improvement and Lean Six Sigma has multiple purposes:
Preventative Measure: Risk Analysis can serve as a first line of defence against potential problems. By identifying potential risks early on, teams can put preventative measures in place to prevent them from occurring. This is likely going to be more cost-effective than addressing the issues after they arise.
Decision Making: Using risk analysis supports informed decision-making. When leaders understand the risks, they can make informed choices that balance the risk with the reward, which should in turn lead to more sustainable business strategies.
Resource Optimization: Conducting a risk analysis can allow for better strategic allocation of resources. Resources can be directed to areas of the business at the greatest risk rather than spreading employees’ focus across areas of low to no risk.
How Risk Analysis is Applied in Continuous Improvement
Using the DMAIC method, you will see how Risk analysis is important in each stage of the process:
- Define: Identify the project goals and potential risks to success.
- Measure: Quantitatively assess the risks to understand their potential impact on the project.
- Analyze: Examine the root causes of risks and how they might affect process variability and waste.
- Improve: Develop and implement strategies to mitigate identified risks.
- Control: Put controls in place to monitor risks over time and ensure that mitigation strategies are effective.
How to Conduct a Risk Analysis
Step 1: Risk Identification
The first step of any risk management process should be the identification of risks. The goal of this step is to develop a comprehensive list of all of the risks that could prevent the process or project of a business from achieving its goals. Here are the methods we recommend using to identify the risks:
Conduct a Brainstorming session with a cross-functional team: This process involves gathering a cross-functional team which is a team with a range of backgrounds who are also stakeholders that are familiar with the process and facilitate a session risk identification, which encourages a flow of ideas to uncover as many potential risks as possible. This can be done with team members noting down potential risks on sticky notes and discussing the risk with the team. The sticky note helps form the documentation of the process.
Other methods include analyzing historical data. This could include reviewing past performance data, incident logs, and previous risk assessments of the process. This can often help identify trends and recurring issues that could pose risks.
Another useful structured method that you can bring into the brainstorming process is using an FMEA analysis. The FMEA which stands for Failure Modes and Effects Analysis, is a systematic approach to identifying all possible failures in a design, manufacturing process, product, or service.
If you are interested in learning more and applying the FMEA to your risk analysis, we recommend taking a look at our FMEA guide.
Step 2: Risk Assessment
Once you have identified a list of potential risks, it is likely going to be a long list where addressing all of them might be difficult. This is where an assessment is needed to understand the extent of the risk’s potential impact on objectives. Common tools for the assessment include:
Risk Matrix: This is a grid that helps you to plot the likelihood of a risk occurring against the severity of its impact. It provides a visual representation of the priority of the risks.
Probability and Impact Grid: Similar to a Risk Matrix, this grid assesses risks by their likelihood and potential impact, but often in more detail and with more dimensions.
Risk Register: A Risk Register is a document that contains all the information about identified risks, including their nature, likelihood, impact, and the measures taken to mitigate them.

Step 3: Risk Prioritization
Risk prioritization is about deciding which risks need immediate attention and which can be monitored over time. It involves sorting the risks based on the assessment carried out in the previous step. High-likelihood, high-impact risks are given the highest priority, while low-likelihood, low-impact ones are lower in priority.
Step 4: Risk Mitigation
This step involves creating action plans for the high-priority risks. The strategies are typically categorized as follows:
- Avoidance: Changing plans to circumvent the risk.
- Reduction: Taking steps to minimize the likelihood of the risk occurring or its impact if it does.
- Transfer: Shifting the risk to a third party, like through insurance or outsourcing.
- Acceptance: Deciding to accept the risk, often because the cost of mitigation is greater than the cost of the risk itself, but preparing contingency plans for dealing with it if it occurs.
Step 5: Risk Monitoring
Continuous monitoring is vital for detecting new risks and assessing the effectiveness of risk responses. Some standards, like ISO 9001, make it a requirement that risk analysis and risk management meetings be done a minimum of once a year. This step is about tracking identified risks, monitoring residual risks, identifying new risks, executing risk response plans, and evaluating their effectiveness over the project life cycle.
Monitoring can be done through regular reviews, audits, and by using key risk indicators that can signal when a risk situation is changing.
Tools for Risk Analysis
FMEA: FMEA is a step-by-step approach for identifying all possible failures in a process, design, product, or service. The aim is to identify potential failure points, understand their causes and effects, and prioritize the failures based on their seriousness, likelihood, and detectability. An FMEA is typically conducted by a cross-functional team and follows these steps:
- Identify Failure Modes: Determine the ways in which a process or product might fail. Failures are errors or defects, especially ones that affect the customer.
- Assess Effects and Causes: For each failure mode, identify all the potential effects on the end customer, and then determine the root causes of each failure mode.
- Determine Severity, Occurrence, and Detection Ratings: Assign a severity rating for each effect, an occurrence rating for each cause, and a detection rating based on the current control plan.
- Calculate Risk Priority Numbers (RPNs): Multiply the severity, occurrence, and detection ratings to get a risk priority number for each failure mode.
- Prioritize and Implement Actions: Focus on the highest RPNs to reduce, eliminate, or control the risks.

Risk Matrix: A Risk Matrix is a simple grid that can be used to rank the severity of risks based on two dimensions: the likelihood of occurrence and the impact if the risk does occur. This tool helps in visualizing and prioritizing risks, facilitating decision-making on where to focus risk mitigation efforts. Here’s how it typically works:
- Define the Likelihood and Impact: Establish a scale for both likelihood and impact (e.g., Low, Medium, High).
- Plot the Risks: Place each identified risk on the matrix according to its likelihood and impact.
- Analyze the Results: Risks in the upper right corner (high likelihood and high impact) are the highest priority, while those in the lower left corner (low likelihood and low impact) are the lowest.
Monte Carlo Simulation:
Monte Carlo Simulation is a statistical method used to model the probability of different outcomes in a process that cannot easily be predicted due to the intervention of random variables. It’s a technique used to understand the impact of risk and uncertainty in prediction and forecasting models. Here’s a brief overview of the process:
- Define a Model: Create a mathematical model of the system or process you’re analyzing.
- Input Random Variables: Identify the inputs that are uncertain and define their probability distributions.
- Run Simulations: Use random sampling to choose values for the uncertain inputs and compute the results for each set of random inputs.
- Analyze the Results: After running many simulations (often thousands or more), you’ll have a probability distribution of the outcome, which can inform decision-making and risk assessment.
Each of these tools serves a specific purpose within Risk Analysis and can be used independently or in combination, depending on the nature of the risks and the needs of the organization. They are widely used in various industries and can be adapted to fit different scenarios and requirements.
Conclusion
In conclusion, Risk Analysis is a tool important for Lean Six Sigma practitioners. It combines methodologies like FMEA, Risk Matrices, and Monte Carlo Simulations to identify, assess, prioritize, mitigate, and monitor risks. These tools, utilized independently or in tandem, cater to diverse industry needs, fitting various scenarios. With its structured approach, Risk Analysis not only fortifies projects against potential pitfalls but also ensures a strategic allocation of resources, fostering informed decision-making and continual process enhancement, thereby playing a pivotal role in achieving sustainable business excellence.
