Cause and Effect Diagram

Cause and Effect Diagram Defined:-

The cause and effect diagram is also called the Ishikawa diagram or the fishbone diagram.

It is a tool for discovering all the possible causes for a particular effect.

The major purpose of this diagram is to act as a first step in problem solving by creating a list of possible causes.

Introduction
The 7 QC Tools are simple statistical tools used for problem solving. These tools were either developed in Japan or introduced to Japan by the Quality Gurus such as Deming and Juran. In terms of importance, these are the most useful. Kaoru Ishikawa has stated that these 7 tools can be used to solve 95 percent of all problems. These tools have been the foundation of Japan's astomishing industrial resurgence after the second world war.
The following are the 7 QC Tools :
1.Pareto Diagram
2.Cause & Effect Diagram
3.Histogram
4.Control Charts
5.Scatter Diagrams
6.Graphs
7.Check Sheets

2 Pareto Diagram
Pareto Diagram is a tool that arranges items in the order of the magnitude of their contribution, thereby identifying a few items exerting maximum influence. This tool is used in SPC and quality improvement for prioritising project and implimentations for improvement, prioritising setting up of corrective action teams to solve problems, identifying products on which most complaints are received, identifying the nature of complaints occurring most often, identifying most frequent causes for rejections or for other similar purposes.

What are 7 QC Tools ?

QC tools are the means for Colleting data , analyzing data , identifying root causes and measuring the results.
THESE TOOLS ARE RELATED TO Numerical DATA processing

7 QC TOOLS

Pareto Diagram
Stratification
Scatter Diagram
Cause and Effect Diagram
Histogram
Check Sheet
Control Chart/Graph

Pareto Diagram

What is Pareto diagram ?

A Pareto diagram is a combination of bar and line graphs of accumulated data, where data associated with a problem (e.g., a defect found, mechanical failure, or a complaint from a customer) are divided into smaller groups by cause or by phenomenon and sorted, for example, by the number of occurrences or the amount of money involved. (The name “Pareto” came from an Italian mathematician who created the diagram.)

When is it used and what results will be obtained?

Please refer to the table on next slide for the usage and benefits of a Pareto diagram. It is mainly used to prioritize matters, and because of its easiness of use, the diagram is used in a wide variety of fields.

Stratification

What is Stratification ?

Stratification means to “divide the whole into smaller portions according to certain criteria.” In case of quality control, stratification generally means to divide data into several groups according to common factors or tendencies (e.g., type of defect and cause of defect).
Dividing into groups “fosters understanding of a situation.” This represents the basic principle of quality control.

When is it used and what results will be obtained?

The “common and basic principle” of quality control is stratification, i.e., to think a matter out by breaking it into smaller portions. Stratification has a number of useful purposes. The table below shows only a few examples of these purposes.

Cause & Effect Diagram

A cause and effect diagram is “a fish-bone diagram that presents a systematic representation of the relationship between the effect (result) and affecting factors (causes).”
Solving a problem in a scientific manner requires clarification of a cause and effect relationship, where the effect (e.g., the result of work) varies according to factors (e.g., facilities and machines used, method of work, workers, and materials and parts used). To obtain a good work result, we must identify the effects of various factors and develop measures to improve the result accordingly.
