Managing a manufacturing process remains a challenging task. The complexity of handling multiple systems and maintaining the supply chain can be enough to make even the most seasoned professional wonder, “Is there a better way?” The simple answer is yes, but the correct solution differs for each factory. Root cause analysis helps manufacturers identify and resolve problems affecting production, quality, safety, or the environment in a timely fashion. With the help of an accurate root cause analysis system, manufacturers gain the ability to stop and prevent problems from escalating into bigger, more expensive challenges.
What are the benefits of RCA?
Saves time: Without a structured approach, it's easy to become distracted by symptoms or to focus on long-term solutions without first identifying the root cause. A structured approach helps you stay focused on eliminating the root cause rather than wasting time focusing on symptoms.
Reduces cost: Eliminating the root cause of problems ensures that they won't recur, saving resources that would otherwise need to be spent on recurring problems.
Increases throughput/reduces downtime: Removing the root causes of problems increases throughput and reduces downtime, which improves productivity and saves costs.
Improves quality: Eliminating the sources of quality issues leads to higher quality products, which can increase customer satisfaction and reduce warranty costs.
Improves safety: Improving safety by eliminating hazardous conditions not only eliminates the risk of injury and lives lost, but also reduces insurance costs, workers' compensation claims, legal fees, reduced fines from regulatory agencies, and lost business due to negative publicity.
Generally, there are six steps involved in root cause analysis:
1) Define the problem: what is happening and what should be happening? The first part of the process is just making sure everybody understands the problem at hand and has a clear picture of what success looks like.
2) Gather data: how often does this happen, when does it happen, where does it happen, etc.? Once you know what the problem is, document basic information about it—when did it start, how often does it occur, where does it occur? The more data you collect at this step, the more easily the next step will be apparent.
3) Identify possible causes: why do you think this is happening? Ask around to see if anybody has any theories about why this is happening. Be careful not to jump to conclusions; your goal here is to gather ideas that can then be tested in the next step.
4) Find solutions: once the root cause of a problem is determined, the solution becomes apparent. This may include training or mechanical modification, or placing new flooring or other infrastructure. It may be necessary to make modifications to the layout of a workspace to ensure smooth operations. Having real-time data and insights at hand when the root cause is determined allows managers to create a relevant, real-world solution based on actual data.
5) Implement solutions: The fifth step of the change management process involves taking action. The intent of step five is to implement the proposed solution that the team has created. Further, the team must take steps to ensure the sustainability of the change.
6) Verify solution effectiveness: In this step, the team examines the effectiveness of the solution by assessing whether it was effective and by considering potential improvements. Assessing the effectiveness of a solution often necessitates turning to various measures, most commonly statistical and/or numerical.
A root cause analysis can be useful in a variety of industries, but it's especially valuable when it comes to manufacturing because it provides a mechanism for analyzing the impact of work process failures on product quality. This is particularly pertinent if you're running a manufacturing operation and begin to experience problems with your major equipment or raw materials. An RCA can be an excellent way to find the underlying cause of these production challenges so that you can make adjustments and improve performance over time. The goal of this process is not to find fault or place blame, but to analyze how a problem came about so that similar issues can be prevented from occurring in the future.
