INTRODUCTION

The objective of this paper is to provide an easy introduction of the Seven QC Tools andfamiliarize with the practical implementation of these tools especially in problem solvingand planning purposes.

This paper includes1- Significance of the Seven QC Tools2- Role of these tools in Total Quality Management3- An overview of the tools4- Tips for successfully using these tools5- Benefits of these tools6- Conclusion

BACKGROUND

Most of us are familiar with the original Seven QC Tools, those are check sheets,graphs, histograms, Pareto diagrams, cause & effect diagram, scatter diagrams andcontrol charts. These tools have proved to be extremely effective instruments for datacollection and analysis, process control and quality improvement. These tools are sosimple to understand and use, that they are regularly used by workplace supervisor, QCcircles leaders as well as by specialist QC staff and there is little doubt that these toolswill continue to be widely used. However these tools are mainly applied on numericaldata. So the need of some tools for organizing the verbal data was felt. As a result ofthis, a committee with the aim of developing QC tools was set up in April 1972 with theaffiliation of the Japanese Scientists and Engineers (JUSE). The committee announcedthe results of its research in 1977 in the form of a set of methods called The SevenQ.C Tools or Seven Management & Planning Tools. The Seven Q.C Tools arespecially designed for sorting out verbal data, putting complex problems into solvableform, simulating creativity, and ensuring that nothing is left out when planning. They arerapidly gaining acceptance as a valuable asset in the campaign for total quality and arewidely used by managers and staff in all departments from R & D through production toafter-sales service. These tools are designed to supplement existing Q.C Tools andmethods and not to replace them.

1. SIGNIFICANCE OF THE SEVEN QC TOOLS

The Seven QC Tools differ from the conventional basic Seven QC Tools, which areused mainly for analyzing numerical data (data based on facts, not fancy). Howeverfacts cannot always be adequately expressed by numerical data alone. For example,suppose that a washing machine is being redesigned. Its purchasers are dissatisfied,complaining that it is difficult to use because its control are poorly positioned. Themodels designers should incorporate this information in the design. Users may alsohave opinions about the machines styling, color, and other characteristics as well as itsconvenience of use. Many such customer requirements cannot be expressednumerically, only verbally. Nevertheless, even verbal statements can be expressions offacts, because it represents facts, we ought to use verbal data as well as numerical datain managing quality. The Seven QC Tools act as a kind of driving force propellingquality management in fresh directions as we enter the age of total quality.The Seven Q.C Tools are Affinity diagrams, Relation diagrams, Tree diagrams, Matrixdiagrams, Priorities matrix, Arrow diagrams and Process decision program charts.When properly used in various combinations, they can dramatically increase theeffectiveness of many TQM activities. They are also compatible with the original seventools, in fact they complement them. When used together, the two sets of tools cangreatly assist the promotion of total quality. The Seven QC Tools are very effective inproblems solving and improving the planning process. Imagine that if someone is giventhe task of improving the efficiency of his companys accounting procedures. As soon ashe sits down to think about it, numerous questions come to mind:

What does efficiency mean?Exactly what procedures need to be made more efficient?What are the particular problems with each of these procedures?Do the companys formal training programs and on -the-job training need to be

improved?What about recent developments in office automation?

The issue seems to have endless ramifications.Like this one, many of the problems we encounter in life are amorphous and complex.Before we can find a solution, we have to define the problem, identify its causes-and-effect relationships, and put it into solvable form. Before we can even start the problem-solving process, we have to create order out of chaos. When people try to tackle fuzzy,intractable problems without the aid of the Seven QC Tools, they often get boggeddown in the frustrating situation. The Seven QC Tools makes it easy to clarify thesituation, establish a plan, and get to the heart of the problem. It also makes it easier toexplain the situation to others and secure their cooperation.

1.1 SIGNIFICANCE IN PROBLEM SOLVING

It is very important that everyone cooperates to solve problems. For this to workeffectively, it is essential for all the members of a group to share their thoughts, pool

their knowledge, and eager to solve the problem. The Seven QC Tools, help thisprocess by using easily understood diagrams to organize both verbal and numericaldata. Figure 1 shows what happens when a group gets together to determine how totackle a problem. It illustrates how each member shares his or her knowledge with thewhole group and how the group exercises collective creativity and imagination in

generating problem-solving ideas.

Flow Charts Defined

A flow chart is a pictorial representation showing all of the steps of aprocess.

Creating a Flow Chart

First, familiarize the participants with the flow chart symbols.

Draw the process flow chart and fill it out in detail about each element.

Analyze the flow chart. Determine which steps add valu e and which dontin the process of simplifying the work.

Examples of When to Use a Flow Chart Two separate stages of a process flow chart should be considered:

The making of the product The finished product
