Flow chart : A symbolic Representation of Sequencial step of a process
Brain Storming :To Generate New Idea for Root Causes / Solutions
Ishikawa Diagram : Also known as Fishbone Diagram
Data collection : can be done through Check sheet Run chart Spread sheet Tabular form
Graphs / Charts :The construction of a control chart is based on statistical principles and statistical distributions, namely normal Distribution
Parato: Parato chart is used to define the problems in most contributing order
Stratification : By material, Machine, Operator, Method, measurement system.
Scatter Plot : To find relationship between two variables. To test for cause and effect relationships

KAIZEN-
The word is from Japan (KAI + ZEN)
