ROOT CAUSE ANALYSIS PowerPoint Presentation

Root Cause Analysis

1. ROOT CAUSE ANALYSIS

2. INTRODUCTION Root cause analysis is simply a tool designed to help incident investigators describe WHAT happened during a particular incident, to determine HOW it happened, and to understand WHY it happened. Only when investigators are able to determine WHY a failure occurred will they be able to specify workable preventive measures.

3. Define Root Cause Analysis?  Root cause analysis involves a range of tools, approaches, and techniques used to uncover the primary causes of problems.  The goal of RCA is to prevent recurring issues from happening by eliminating their root causes. The process follows a chain of causes and effects to pinpoint the origin. 

4. Toyota founder Sakichi Toyoda originally developed Root cause analysis to improve the efficiency of the auto making manufacturing process. RCA is a critical component of the international   Total Quality Management (TQM)  movement, the corporate process improvement movement, and the drive for  quality control . 

5. What is root cause analysis? A standard process of: identifying a problem containing and analyzing the problem defining the root cause defining and implementing the actions required to eliminate the root cause validating that the corrective action prevented recurrence of problem

6. Benefits By eliminating the root cause… You save time and money! Problems are not repeated Reduce rework, retest, re-inspect, poor quality costs, etc… Problems are prevented in other areas Communication improves between groups and Process cycle times improve (no rework loops) Secure long term company performance and profits

10. Definition and purpose Definition: Although there is substantial debate concerning the definition of a root cause, as defined in this system: A root cause is the most basic cause that can reasonably be identified and that management has control to fix. This definition contains three key elements: Basic Cause Reasonably Identified Control to fix 1 ) Basic Cause The goal of the investigator should be to identify basic causes. The more specific we can be about the reasons why an incident occurred, the easier it is to arrive at recommendations that will prevent recurrence of the events leading up to the incident. 2) Reasonably Identified Incident investigations must be completed in a reasonable time frame. It is not practical to keep valuable manpower occupied indefinitely searching for the causes of incidents. Root cause analysis, to be effective, must help investigators to get the most out of the time that they have allotted for the investigation.

11. 3) Control to Fix: Investigators should avoid using general cause classifications such as "operator error." Such causes are not specific enough to allow those in charge to rectify the situation. Management needs to know exactly why a failure occurred before action can be taken to prevent recurrence. If the investigators arrive at vague recommendations such as "Remind operator to be alert at all times," then they have probably not found a basic enough cause and need to expend more effort in the investigation process.

12. Purpose of RCA The purpose of Root Cause Analysis (RCA) is to systematically identify and address the underlying causes of problems or issues, rather than merely treating their symptoms. The primary objectives and purposes of RCA include: 1. Preventing Recurrence: Identifying and eliminating the root causes of problems helps prevent the recurrence of similar issues in the future. This leads to long-term solutions rather than short-term fixes.

Understanding the root causes of challenges can lead to the development of new and improved solutions.

19. Differentiating between symptoms and Root causes Symptoms A symptom is a sign or indication of a root cause, but it is not, by itself, a cause. Most often, symptoms lack specificity and are difficult to categorize. It is very difficult to develop solutions to directly address a symptom. Root causes A root cause is the real reason for a business or performance problem. Root causes are specific and can be easily categorized. Solutions can be implemented that either remove or mitigate the effects of a root cause.

22. Common tools and techniques Here are some common tools and techniques used in RCA: Fishbone Diagram (Ishikawa or Cause-and-Effect Diagram) 5 Whys Failure Mode and Effects Analysis (FMEA) Pareto Analysis Fault Tree Analysis (FTA) Bowtie Analysis Barrier Analysis Root Cause Mapping Change Analysis Control Charts Scatter Diagrams Affinity Diagrams Process Mapping

23. Fishbone Diagram (Ishikawa or Cause-and-Effect Diagram) It is also known as Ishikawa diagram or Cause-and-Effect diagram, is a visual representation used to analyze and identify the possible causes of a specific problem or effect. A fishbone diagram is a visualization tool for categorizing the potential causes of a problem. This tool is used in order to identify a problem’s root causes. Typically used for  root cause analysis . It was developed by Dr. Kaoru Ishikawa, a Japanese quality control expert. The diagram takes its name from its appearance, which resembles the skeleton of a fish.

24. Use of fishbone diagram A few reasons a team might want to consider using a fishbone diagram are: To identify the possible causes of a problem. To help develop a product that addresses issues within current market offerings. To reveal bottlenecks or areas of weakness in a business process. To avoid reoccurring issues or employee burnout. To ensure that any corrective actions put into place will resolve the issue.

25. 5 Whys The "5 Whys" is a technique used in Root Cause Analysis (RCA) to identify the underlying causes of a problem by asking "why" multiple times. Here's an example: Problem 1: Production line downtime 1. Why did the production line stop ? Because the machine malfunctioned. 2. Why did the machine malfunction ? Because a critical component failed.

26. 5 Whys 3. Why did the critical component fail ? Because it was not properly maintained. 4. Why was the component not properly maintained ? -Because the maintenance schedule was not followed. 5. Why was the maintenance schedule not followed ? Because there was a lack of communication and coordination between the maintenance team and production scheduling.

27. 5 Whys Problem 2: Production line downtime 1. Why did the production line stop? Answer : The machine overheated. 2. Why did the machine overheat? Answer : The cooling system failed. 3. Why did the cooling system fail? Answer : The pump stopped working. 4. Why did the pump stop working? Answer : It was not receiving regular maintenance. 5. Why was the pump not receiving regular maintenance? Answer : There was no scheduled maintenance plan in place.

28. 5 Whys Problem: Production output is consistently below target. Why is the production output below target? Because the machines are frequently breaking down. Why are the machines frequently breaking down? Because regular maintenance is not being performed. Why is regular maintenance not being performed? Because there is a shortage of maintenance staff. Why is there a shortage of maintenance staff? Because the company didn't hire additional staff to keep up with increased production demands. Why didn't the company hire additional staff to keep up with increased production demands? Because there was a budget constraint, and hiring was frozen.

29. 5 Whys It's important to note that the number of "whys" may vary based on the complexity of the issue. The objective is to continue asking "why" until a clear and actionable root cause is identified, enabling effective problem resolution.

30. Scatter Diagrams A scatter diagram, also known as a scatter plot or scatter graph, is a visual representation of the relationship between two variables. It is commonly used in statistics and data analysis to examine the correlation or association between two quantitative variables. The data points are plotted on a Cartesian plane, where each point represents a unique combination of values for the two variables . Here are the key components and characteristics of a scatter diagram : Horizontal Axis (X-Axis ) Vertical Axis (Y-Axis ) Data Points Trend Line Scatter diagrams are commonly used in various fields, including statistics, engineering, economics, and the sciences, to gain insights into the relationships between variables and to inform further analysis or decision-making.

31. Pareto Analysis Pareto Analysis, named after the Italian economist Vilfredo Pareto, is a decision-making technique that prioritizes and focuses on the most significant factors contributing to a particular problem or situation. It is based on the principle known as the "80/20 rule," which states that approximately 80 % of effects come from 20% of causes . The main steps in conducting Pareto Analysis are as follows : Identify the Problem or Issues Collect Data Categorize the Data Calculate the Frequency of Each Category Calculate Cumulative Frequency Create a Pareto Chart Identify the Vital Few Focus on Improvement Pareto Analysis is a valuable tool in prioritizing efforts and resources to address the most significant issues. It is widely used in quality management, project management, and problem-solving across various industries .

32. Control Charts A Control Chart, also known as a Shewhart chart or process-behavior chart, is a statistical tool used in Root Cause Analysis (RCA) to monitor and control processes over time. It is particularly valuable for identifying variations or changes in a process and determining whether these variations are within acceptable limits. Control Charts help distinguish between common cause variation (inherent to the process) and special cause variation (due to external factors or specific events ). Here are the key components and concepts associated with Control Charts in the context of Root Cause Analysis : Process Data : Data Subgroups Control Limits Central Line Data Points on the Chart Pattern Recognition Control Charts are widely used in industries such as manufacturing, healthcare, and quality control, where maintaining consistent and predictable processes is crucial for operational excellence.

33. Fault Tree Analysis (FTA) Definition : Fault tree analysis (FTA) is a systematic approach that identifies the primary causes of operational and maintenance (O&M) issues. It’s a deductive analysis tool that begins with a general conclusion before working backward to identify potential causes. Maintenance leaders complete this problem-solving exercise using visual representations of cause and effect known as  fault tree diagrams .   USED: Fault Tree Analysis (FTA) is a systematic and graphical method used in Root Cause Analysis (RCA) to identify the root causes of a specific event or failure. It is particularly effective in industries where safety and reliability are critical, such as nuclear power, aviation, chemical manufacturing, and aerospace. FTA is used to analyze complex systems and understand how various events or failures contribute to a specific undesired outcome .

38. 5 Whys technique The 5 Whys is a problem-solving technique that involves asking "why" repeatedly to identify the root cause of a problem or issue. It is a simple and effective method for digging deeper into the underlying factors contributing to a problem. The goal is to ask "why" five times (or more) until the true root cause is identified, enabling organizations to address issues at their source rather than treating symptoms . There's a few step to using the 5 whys technique: Identify the Problem: Clearly define the problem or the undesired outcome you want to address. Ask "Why" for the First Time: Start by asking why the problem occurred. This is the first level of inquiry. Example: "Why did the production output decrease?"

39. 5 Whys technique Repeat the Question for Each Answer: For each answer given in response to the previous "why," ask "why" again to probe deeper into the causes. Example: Answer 1: "The machines broke down." Second "Why": "Why did the machines break down?" Continue Asking "Why": Repeat the process, asking "why" for each subsequent answer, until you reach the fifth level or until a clear and actionable root cause is identified. Example: Answer 2: "There was a lack of preventive maintenance." Third "Why": "Why was there a lack of preventive maintenance ?"

40. 5 Whys technique Identify the Root Cause: Continue asking "why" until you reach a point where the answer is a fundamental issue that, when addressed, can prevent the recurrence of the problem. Example: Answer 3: "There was a shortage of maintenance staff." Fourth "Why": "Why was there a shortage of maintenance staff?" Answer 4: "The company implemented a hiring freeze due to budget constraints." In this example, The fifth "why" revealed the root cause – a budget constraint leading to a hiring freeze, resulting in a shortage of maintenance staff and ultimately causing a decrease in production output.

41. Failure Mode and Effects Analysis (FMEA ) Failure Mode and Effects Analysis (FMEA) is a systematic and proactive approach used in various industries to identify and prioritize potential failure modes in a process, system, or product, assess their potential effects, and develop strategies to prevent or mitigate their impact. FMEA is commonly employed in manufacturing, healthcare, automotive, aerospace, and other fields where preventing failures and improving reliability are critical objectives . There are some steps of failure mode and effects analysis: Select the Process, System, or Product Assemble a Cross-Functional Team Identify Potential Failure Modes Determine the Effects of Each Failure Mode Assign Severity Ratings Identify Causes and Potential Detection Methods Assign Occurrence Ratings Assign Detection Ratings Calculate Risk Priority Numbers (RPN ) Prioritize and Develop Action Plans Implement Improvements Monitor and Review
