Qualityze Podcast : Mastering Root Cause Analysis: A Review of the Best Investigation Tools
Welcome to the second series of problem or issue investigation processes. In this series, we’ll discuss the several different and best investigation tools that can be used to identify and resolve problems or issues in various settings, including business, manufacturing, and healthcare. Listed below are some of the most commonly used tools and how to use them efficiently
The 5Ws (Who, What, When, Where, Why) tool is a simple yet effective method for gathering information about a particular problem or situation. It can be used to identify the key facts and details necessary to understand a problem or make a decision. Here are the steps for using the 5 Ws tool:
It’s important to focus on the problem, ask open-ended questions, involve multiple perspectives, and persist in getting to the root cause. The 5 Whys tool is typically used to identify the root cause of a problem. It is a simple, but powerful tool that involves asking “why” five times to get to the underlying cause of an issue. The 5 Whys tool is particularly useful when dealing with complex or recurring problems and when you want to get to root causes rather than addressing the symptoms.
To use the 5 Whys tool:
For example, if the problem is that a machine is not working properly, you might ask:
Nonconformance Management Software optimizes your quality program to streamline ISO 9001 compliance. Qualityze makes the top choice by reducing rework, eliminating product recalls and improving customer satisfaction.
A fishbone diagram, also known as an Ishikawa diagram or a cause-and-effect diagram, is typically used in problem-solving and root-cause analysis to identify the potential causes of a problem. It is a graphical representation that displays all the possible causes of a problem and their relationships.
The fishbone diagram is particularly useful when dealing with complex problems where multiple causes may contribute to the issue. It is also helpful in bringing together different perspectives from individuals or teams involved in the problem and identifying the most significant causes to prioritize efforts for resolution. Fishbone diagrams are commonly used in quality control, product development, process improvement, customer complaints, risk management, and other applications. To use the fishbone tool, follow these steps:
To use the Fishbone diagram tool effectively, involving a cross-functional team with a range of knowledge and expertise related to the problem is important. The team can brainstorm potential causes and then organize them into categories that align with the various “bones” of the fish. This can help to identify the most likely root causes and to develop solutions to address them. Quality management software for manufacturing of Qualityze is designed with cloud-based QMS system that allows to optimize and automates all the aspect of global manufacturing management process to truly leverage manufacturing capability to be a competitive force.
The Pareto chart is a graphical tool used to identify the key contributors to a problem. For example, it states that roughly 80% of effects come from 20% of causes. The Pareto chart is particularly useful for identifying the most significant factors contributing to a problem, allowing you to focus on areas where you can make the biggest difference.
Here are some steps for using the Pareto chart:
The Pareto chart can be used in various applications, including quality control, process improvement, and customer service.

FMEA tool is typically used during the design or manufacturing process to identify potential failures and their impact on the product or process. FMEA is a proactive tool used to assess the risks associated with potential failures and to implement appropriate measures to reduce or eliminate those risks.
The steps for conducting an FMEA include the following:
Establishing an interval to review and update the FMEA periodically is always a good practice to ensure continued effectiveness. Quality management software for lifescience is one of the most advanced solutions for quality management in highly regulated fields. The process of configurable and easy-to-use features ensures a smooth transition process.
A thought map, or mind map, or concept map is a diagram used to visually organize information around a central idea or concept. It can be useful for problem investigation as it allows you to break down a complex problem into its parts and visualize the relationships between them.
To use a thought map for problem investigation, start by writing the problem statement in the center of the map. Then, brainstorm all possible causes or contributing factors to the problem and write them down as branches stemming from the center. Next, you can further brainstorm sub-causes or related factors from each branch, creating a branching hierarchy of ideas.
Use colors, symbols, and images to help organize and categorize the information, making identifying patterns and relationships between the different factors easier. By creating a thought map, you can gain a clearer picture of the problem and its underlying causes, making it easier to develop a targeted solution.
A timeline of change is a graphical representation of changes that have occurred over time. It is a useful tool for problem investigation when the problem is related to changes that have taken place. Here are the steps for using a timeline of change:
Once the root cause has been determined, implement a solution to address the problem. Finally, monitor the situation to ensure that the problem has been resolved.
The entire process can be made easier using a comprehensive and efficient CAPA management software solution like Qualityze. The user-friendly interface and powerful features enable you to streamline your CAPA processes, identify and address issues, and ensure compliance with regulatory requirements.
One of the biggest advantages of using Qualityze is its ability to integrate with various and best investigation tools without any hassles or groundwork. This means you can choose the tool that works best for your organization, whether it’s a root cause analysis tool, fishbone diagram, or 5 Whys analysis, and seamlessly incorporate it into your CAPA process.
By using Qualityze, you can significantly reduce the time and effort required for CAPA management while also improving the quality and effectiveness of your best investigation tools.
