7 QC Tools

For Systematic Process Problem Solving & Quick Troubleshooting

(Suitable for Technicians, Line Leaders, Supervisors and Technical Operators)


Course Overview

The 7QC Tool is so called because it employed a systematic approach using graphical method to provide for ease in data presentation and meaningful communication. It was first promoted by Kaoru Ishikawa a renowned quality expert in Japan for use throughout Japan. The success of the 7QC tool lies in the systematic application of tools itself to help the workforce visualize the graphical communication and thereby increase their understanding of the key issues of the problem at hand.

The workforce of manufacturing is the most importance front line control of Productivity and Quality. Total Quality Control must therefore be based upon educating the whole workforce to deal with day-to-day basic quality issues that should be nibbled in the bud and prevented from arising. This can only be done with the collaboration of the workforce of manufacturing to successfully implement Total Quality Control. The 7QC Tools are the most important practical day-to-day useful techniques for:

a) Tool 1 – Selecting The Right Problem To Solve
b) Tool 2 – Know How To Collect The Factual Data
c) Tool 3 – Stratify The Data Into Meaningful Grouping
d) Tool 4 – Apply The Cause & Effect Analysis To Find The Most Likely Cause
e) Tool 5 – Know How To Verify Whether The Recommended Solution Is The Right One
f) Tool 6 – Continue To Monitor The Process To Check For Shift In Operational Process Stability
g) Tool 7 – Know How To Troubleshoot The Quality & Productivity Problem For Fast Containment Action


The Objectives

This training is designed with the main objective to achieve the following results:-

1. Develop the thinking ability of the operators to think systematically in adopting 7QC Tools approach in problem solving.
2. Train and educate the workforce to master each of the 7QC Tools so that they understand their purpose and know how to apply them in problem solving.
3. Equip the workforce with the technical know-how of problem solving and how each step of the problem solving in related to the 7QC Tools.
4. Develop the workforce understanding on symptoms of the problem and root cause and different in approach in addressing them.
5. Provide a quick troubleshooting skill to help the workforce identify the location of the problem.


Training Method

a) The master trainer will provide full step-by-step instruction on the 7QC Methodology as well as identification of useful charting method and full instruction on how to make each type of chart,
b) Illustration of chart construction method and chart use will be provided.
c) The workforce are given opportunity for hands-on the construction of the charts themselves for each step of the 7QC Tools process.
d) The workforce will be quipped with 7QC Approach as well as Quick Troubleshooting Approach to prevent the problem from causing further damage.


Why APRC 7QC Tools Stand Out

The master trainer, C.H Wong was involved in conducting Root Cause Analysis for Rolls Royce Group in Asia Pacific for many years. There are also many tools in 7QC which he thoroughly understood their application since he used them while working in Industrial Engineering and Manufacturing Engineering in General Electric Company. Therefore the participants will benefit from his wealth of experience in using these tools as well as involvement in conducting Root Cause Analysis for Rolls Royce Company. That is why, Tool 7, includes a very important component called Decision Tree, that is for Quick Troubleshooting. It is widely used in Rolls Royce’s approach.
