Learn more in Incident Management vs Problem Management. RCA has a wide range of advantages detailed below , but it is dramatically beneficial in the continuous atmosphere of software development and information technology for two main reasons:. Even though performing root cause analysis might feel time consuming, the opportunity to eliminate or mitigate risks and root causes is undeniably worthwhile.

Some of the basic principles of RCA can help organizations ensure they are following the correct methodology:. The specific map of root cause analysis may look slightly different across organizations and industries. But here are the most common steps, in order, to perform RCA:. Remember, in order to have an effective RCA it is important that the team recognizes that processes cause the problems not people. Pointing fingers and placing blame on specific workers will not solve anything.

Learn more about the importance of a blameless culture when performing an incident postmortem —the final step of your root cause analysis. You can perform RCA using a variety of techniques.

We highlight four well-known RCA techniques below—use the technique that meets your specific situation. One of the simplest and most commonly utilized tools in conducting an RCA is the 5 Whys method.

Even though the method seems explicit enough, this approach is still meant to be flexible depending on the scenario. Sometimes five whys will be enough. Or, you could use additional techniques to identify the root cause.

Pareto charts identify the most significant factor among a large set of factors causing a problem or event. A Pareto chart is a combined bar and line chart, where the factors are plotted as bars arranged in descending order.

The chart is accompanied by a line graph showing the cumulative totals of each factor, left to right. You might know the Ishiwaka Diagram by other names: the fishbone, the herringbone, the cause-and-effect, and, our favorite, the Fishikawa diagram. The Ishikawa diagram is a great visualization tool for brainstorming and discovering multiple root causes. It is shaped like a fish skeleton, with the head on the right and the possible causes shown as fishbones to the left.

Scatter diagrams , or scatter plots, use regression analysis to graph pairs of numerical data to determine relationships. Follow us. USA - English. Select your country. Nederland Nederlands.

In this case, you might have to go through the RCA process again to make sure that you get to the actual root cause. For example, you notice the machine is leaking fluid, so you patch the hole in the metal. In that case, you will test whether the same factors can be replicated in other scenarios and environments. The next step would be to replicate the problem to test whether you actually fixed the root issue.

RCA is about solving problems. But one of the most significant benefits for you is that being skilled at RCA makes you look good. And it can even make a big enough impression that it can change your career trajectory for the better. Limble has actually helped people get promotions because it makes them better at their jobs! RCA can be accomplished using many different tools and techniques. And even though those processes may look different, they all arrive at the same end goal: fixing the root cause of the issue.

Start with the obvious: What is the problem? By defining the problem, the symptoms, and what you can see happening, you set the scope and direction of the analysis. A well-defined problem statement also helps determine the scale and scope of the potential solution to be implemented.

Collect all available data related to the incident. How long has this problem existed? What is the impact of the problem? Take, for example, machine failure in a manufacturing plant. Inspecting the machine in person also provides information that could be beneficial for root cause analysis. It will be easy for facilities that run predictive maintenance to collate data quickly.

Establish a timeline of events. This will help you determine which factors among the data collected are worth investigating.

RCA needs data points that potentially lead to the root cause. Putting events and data in chronological order helps to differentiate causal events from non-causal events. From the data collected, you can identify correlations between various events, their timing, and other data collected.

Remember that correlation does not mean causation. The next step is to map out a causal graph. These graphs are used to represent the relationship between events that happened and the data collected.

Find out what event caused another event. This will help you find the actual root cause. From the data collected, chronological sequencing, and clustering, we should be able to create a causal graph or use one of the root cause analysis tools we discuss later. You can use this graph to represent the relationship between various events that occurred and the data collected.

The different paths are given different probability weights. They can serve as a visual tool to track down the root cause. Example of a causal graph. Source: Adam Kelleher on Medium.

You can then map it against the scope defined in your initial problem statement. If the solution works with your available resources, it can be implemented. Fixing the root cause should eliminate the issues. There can be multiple solutions applied to solve a single issue. For example, the root cause could be the wear of a bearing, which happened much earlier than expected.

In this case, the procedure has to be adjusted to change the bearing at an earlier time. Similar steps to avoid recurrence of fault can be changes in the maintenance schedule, different modes of maintenance, changes in design, different OEM vendors , etc. The implemented solution will have to be in line with the available resources. So, if the root cause is pushing the machine too hard, the obvious answer is to shorten the machine run time. There are many tried and trusted frameworks available to execute RCA.

None of these methods are foolproof, but they provide a solid base for how to go about root problem investigation. Each method has its own list of benefits and shortfalls. Some methods are more suitable for different industries and types of problems. You and your company should have your own unique protocol when conducting RCA. In some instances, external consultants might be brought in to conduct RCA.

In such cases, the consultants will generally have their own preferred technique or a combination of techniques they use. This is one of the reasons why it is hard to create a universal template for RCA that everyone can follow.

At that point, you should have reached the root cause of the problem. The Ishikawa method for root cause analysis emerged from quality control techniques employed in the Japanese shipbuilding industry by Kaoru Ishikawa. The shape of the resulting diagram looks like a fishbone, which is why it is called a fishbone diagram. The 5 Ms are:.

The problem or fault is written down at the far right end, where the fish head would be. The cause of the problem is represented along the horizontal line. Further effects and their respective causes are written down along the fish bones representing each of the 5 Ms. This process continues until the team is convinced that the root cause is identified. FMEA is a proactive approach to root cause analysis, preventing potential failures of a machine or system.

It is a combination of reliability engineering , safety engineering, and quality control efforts. It tries to predict future failures and defects by analyzing past data. A diverse cross-functional team is essential when using FMEA. You will need to clearly define and communicate the scope of the analysis to your team members. Each subsystem, design, and process is closely reviewed.

The purpose, need, and function of each system are questioned. Potential failure modes are brainstormed. Failure of similar processes and products in the past can also be analyzed. The potential effects and disruptions that could be caused by each of the identified failure modes are assessed and used to calculate its RPN.

If the failure mode has a higher RPN than a company is comfortable with, you can address this by changing one or more factors outlined in the image above.
