The document provides an overview of the 5 Whys root cause analysis tool. The 5 Whys involves asking "Why?" five times to determine the root cause of a problem. It should address both why a defective part was made and why the defect was not detected earlier. While typically involving five questions, the number may vary depending on the complexity of the problem. The tool helps analyze problems by tracing them back from obvious to less obvious causes through a series of why questions. The goal is to identify systemic root causes that allow problems rather than just resolving the specific problem.7 quality control tools

After World War II, Japan adopted quality as an economic strategy and selected seven statistical tools to analyze quality problems and drive continuous improvement. The seven tools - Pareto charts, cause-and-effect diagrams, histograms, control charts, scatter plots, check sheets, and flow charts - can identify up to 95% of issues. Each tool has a specific purpose, such as prioritizing problems with Pareto charts or identifying relationships between variables with scatter plots. Using these tools, Japanese companies were able to dramatically improve quality and economic performance.5 Whys Training.ppt

The 5 Whys is a root cause analysis tool used to identify the underlying cause of problems. It involves asking "why" five times to get to the root cause. You start with the problem statement and ask why it occurred, then why the answer to the previous why occurred, until you identify the root cause. It is important to clearly define the problem, follow the thought process through five whys without jumping to conclusions, and ensure any root cause identified can reproduce the problem. The outcome is the root cause rather than just resolving the problem.ISO QMS 9001: 2015 clauses

Root cause analysis (RCA) aims to identify the underlying causes of problems in order to develop effective solutions. The key principles of RCA are to correct root causes rather than symptoms, perform analysis systematically using evidence, and identify multiple root causes that may require multiple solutions. The general RCA process involves defining the problem, gathering data, identifying contributing issues and root causes, developing recommendations to prevent recurrence, implementing changes, and ensuring effectiveness. Tools for RCA include cause mapping, 5 whys, Pareto charts, fishbone diagrams, and charts/graphs. Effective RCA requires thorough information gathering and an understanding of the sequence of events.Root cause analysis - tools and process

The New 7 QC tools were developed in the 1970s as an extension of the original Basic 7 QC tools to develop more techniques with a design approach. The seven New 7 QC tools are affinity diagram, relationship diagram, tree diagram, matrix diagram, priority matrix, precision/decision program chart, and activity network diagram. They help define problems, organize ideas and data, determine relationships, and support decision-making. The tools can be used by various roles across different stages of a process to improve quality, efficiency, and problem-solving.Pareto Chart Explained with Example With Excel Template.pdf

The document discusses Pareto analysis and provides an example of its use. It begins with an overview of Pareto analysis and its use in identifying the "vital few" causes that contribute to the majority of problems. It then provides an example using defect data from a ceiling fan manufacturing plant. A Pareto chart is created from the defect data, showing that regulators and bent screws account for over 70% of defects. The summary focuses on addressing these two vital issues first to achieve maximum quality improvements.The 5 Dimensions of Problem Solving using Dinna: Case Study in the Electronic...

Based on the principle that perfection is a divine criterion, process management exists on the one hand to achieve excellence (near perfection) and on the other hand to avoid imperfection. In other words, Operational Excellence (EO) is one of the approaches, when used rigorously, aims to maximize performance. Therefore, the mastery of problem solving remains necessary to achieve such performance level. There are many tools that we can use whether in continuous improvement for the resolution of chronic problems (KAIZEN, DMAIC, Lean six sigma) or in resolution of sporadic defects (8D, PDCA, QRQC ...). However, these methodologies often use the same basic tools (Ishikawa diagram, 5 why, tree of causes) to identify potential causes and root causes. This result in three levels of causes: occurrence, no detection and system. The research presents the development of DINNA diagram [1] as an effective and efficient process that links the Ishikawa diagram and the 5 why method to identify the root causes and avoid recurrence. The ultimate objective is to achieve the same result if two working groups with similar skills analyse the same problem separately, to achieve this, the consistent application of a robust methodology is required. Therefore, we are talking about 5 dimensions; occurrence, non-detection, system, effectiveness and efficiency. As such, the paper offers a solution that is both effective and efficient to help practitioners of industrial problem solving avoid missing the real root cause and save costs following a wrong decision.

The 5 Whys method is used to identify the root cause of problems by repeatedly asking "why?". In the example, parts were dropping on the floor because the machine arm could not reach the conveyor. Upon further questioning, it was revealed that a scraper seal at the base of the arm had come loose due to lack of lubrication, preventing full rotation of the arm. The 5 Whys technique peeled back the layers to uncover the true root cause behind the problem.

The document discusses root cause analysis (RCA), which aims to identify the underlying causes of problems. It defines RCA and lists its key principles, including that addressing root causes is more effective than just treating symptoms. A general 7-step process for performing RCA is outlined. Cause mapping is introduced as a visual way to analyze all elements that contributed to an issue. Common tools for RCA include 5 whys, fishbone diagrams, Pareto charts, and graphs. Best practices like thoroughly collecting information and understanding what happened are recommended for effective RCA.The 7 QC Tools - English (19 Pages).ppt

Self-improvement. Personal growth. These terms often conjure images of intense seminars, complex philosophies, or relentless positivity. But what if the path to becoming a better, happier you was paved with wit, sarcasm, and a healthy dose of existential absurdity? Enter Woody Allen, the iconic filmmaker and comedian whose neurotic musings, surprisingly, offer profound insights into navigating the human condition. Forget the forced Zen; sometimes, the deepest growth sprouts from acknowledging lifes inherent ridiculousness, just like Woody does.

- 2. The Basic 7 QC tools first emphasized by Kaoru Ishikawa, a professor of engineering (applied chemistry) at Tokyo University and the father of QC Circles. "The term '7 tools for QC' is named after the 7 tools of the famous warrior, Benkei. Benkei owned 7 weapons, which he used to win all his battles. Similarly, from my own experience, you will find that you will be able to solve 95% of the problems around you if you wisely use the 7 tools of QC." -Kaoru Ishikawa (Father of QC Circle) 1/05/2021 tqmforbetterfuture@gmail.com 2
- 3. 1 . C H E C K S H E E T Check sheet, is basically a data collection sheet, used to record data for further processing. The data collection sheet should be pre-printed and highly systematic and structured, such that identification of problems becomes easier. 1/05/2021 tqmforbetterfuture@gmail.com 3
- 4. 2 . S T R AT I F I C AT I O N Stratification is the process of breaking down or sorting a large database so that, meaning subsets, classifications, or groups can be developed. The main reason is to clearly identify what, when, where, how, who, and why of any problems. It also called as Cluster Analysis. 1/05/2021 tqmforbetterfuture@gmail.com 4
- 5. 3 . H I S TO G R A M Histogram is the most commonly used graph to show frequency distribution. The most commonly used graph for showing frequency distributions, or how often each different value in a set of data occurs. 1/05/2021 tqmforbetterfuture@gmail.com 5
- 6. 4 . C A U S E E F F E C T D I A G R A M Cause-Effect Diagram is also known as Fishbone diagram and Ishikawa Diagram. This identifies one-by-one causes (/factors) from brainstorming sessions and then classified into groups i.e., 4M1E. But the grouping can be varied. The objective is finding out as many as possible causes. 1/05/2021 tqmforbetterfuture@gmail.com 6
- 7. 5 . PA R E TO C H A R T According to Pareto Principle, about 20 percent of causes/reasons are responsible for 80 percent effects/defects. That means only few reasons are responsible for majority of the problems. These few (20%causes) are known as Vital Few, whereas the rest many (80% causes) are known as Trivial Many. The objective of Pareto Chart is to identify the Vital Few Causes. 1/05/2021 tqmforbetterfuture@gmail.com 7
- 8. 6 . S C AT T E R D I A G R A M Scatter diagram is used to find out the relationship between two variables. If the variables are correlated, the points will fall along a line, or very closed to line. 1/05/2021 tqmforbetterfuture@gmail.com 8
- 9. 7 . C O N T R O L C H A R T Control Chart, the seventh tool of TQM, mostly used in SQC/SPC. Also known as Shewhart Control Chart. This chart helps in controlling the process, by analyzing whether it goes out-of-control or in- control situation. An out-of-control situation indicates necessity of immediate intervention, in order to take it back to normal in-control situation. 1/05/2021 tqmforbetterfuture@gmail.com 9
