Cause and Effect or Ishikawa Diagram
Overview
Cause and Effect or Ishikawa Diagram shows the causes of a particular event. It can be used for product design and to check its quality to identify possible factors causing an overall effect. You can group causes into categories to find sources of variation.
When To Use Cause And Effect Analysis
Cause and effect analysis can be used in many ways but its primary purpose is to help you solve problems the problem is the effect whatever brings about that effect is the cause, the cause and effect technique will speed the identification of the true cause or causes so the corrective action can be taken
Root cause analysis
Problem exploration
Identifying possible data requirements
Developing objectives for solutions
Narrowing down causes
Also, Identifying the root causes of any problem
Meanwhile, Relationship between the causes of a problem
First of all, define a problem that will be head of the fish then decide major causes and effects leading to a problem.
Steps
5 Steps To Do Cause And Effect Analysis
Step 1: Define The Problem
First, write in the quality problem on the right-hand side and draw an arrow pointing to it. The problem which needs analysis should be written
Step 2: Decide Major Causes And Effects Leading To A Problem
Determine the major categories for grouping possible causes the most popular examples of major causes are the four M’s machines materials manpower and methods you can use more or fewer major causes and you do not have to use any of the four M’s if they do not apply it is just an easy way to get started if the four M’s are not appropriate there are numerous other choices these are some examples the number of major causes can vary and can be more or less than four
Step 3: Brainstorm And Analyze
You’ve to gather a team and do a brainstorming activity. In your team 3-4 or more than that people will be discussing what the problem is and they will come with their idea so we can take the best idea. Brainstorm and analyze will be happening on problem and major causes detail. Brainstorming is a very important activity in cause and effect analysis tool
Meanwhile, When brainstorming it is important to remember that Clues may surround us but a less our mental blindfold is removed we may miss seeing or thinking of those causes that are important as the ideas are written down. The chart should not look like the top diagram.
Also, The purpose of the cause-and-effect chart is to group like ideas together with a big help to the leader is for a member.
Step 4: Categorize Causes
Find possible causes leading to a problem. You’ve to see what exact cause is leading to a problem. You’ve to continue till you’ve found the root cause of the problem
Step 5: Action Plan
After you have analyzed the problem and find its causes, the last step is to develop an action plan so that you would not repeat the same mistake again
