Ishikawa diagrams (also called fishbone diagrams, [ 1] herringbone diagrams, cause-and-effect diagrams) are causal diagrams created by Kaoru Ishikawa that show the potential causes of a specific event. [ 2] Common uses of the Ishikawa diagram are product design and quality defect prevention to identify potential factors causing an overall effect.
Eight Disciplines Methodology ( 8D) is a method or model developed at Ford Motor Company used to approach and to resolve problems, typically employed by quality engineers or other professionals. Focused on product and process improvement, its purpose is to identify, correct, and eliminate recurring problems. [ 1]
Based on T.P. Wright's original work on the man-machine-environment triad [ 3] at Cornell University, the 5M model incorporates a diagram of 3 interlocking circles and one all-encompassing circle. The smaller circles are labeled Man, Machine, and Medium; the intersecting space in the middle, where they all meet, is labeled Mission; while the ...
Control chart. Histogram. Pareto chart. Scatter diagram. Flow chart. Run chart. The seven basic tools of quality are a fixed set of visual exercises identified as being most helpful in troubleshooting issues related to quality. [ 1] They are called basic because they are suitable for people with little formal training in statistics and because ...
Accident analysis is a process carried out in order to determine the cause or causes of an accident (that can result in single or multiple outcomes) so as to prevent further accidents of a similar kind. It is part of accident investigation or incident investigation . These analyses may be performed by a range of experts, including forensic ...
Five whys. Five whys (or 5 whys) is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem. [ 1] The primary goal of the technique is to determine the root cause of a defect or problem by repeating the question "why?"
A quality circle is a small group of workers that work in the same area or do similar sorts of work and meet once a week for an hour to identify, analyse, and resolve work-related issues. The objective is to improve the quality, productivity, and overall performance of the company, as well as the workers' quality of life at work.
A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
