ADVANCE QC TOOLS or NEW 7 QC TOOLS or 7 MANAGEMENT TOOLS

New seven QC tools are made to analyze non-quantity information (knowledge) mainly. Those tools are could be said as reasoning methods. "New seven QC tools" is also called "N7"

1. Affinity diagram is a tool/method that gathers large amounts of intertwined verbal data. It organizes the verbal data into groups based on natural relationship. Such formation of distinct groups help a meaningful picture to emerge, thereby making it feasible for further analysis and to find a solution to the problem.

Advantages of Affinity Diagrams:

ò        Facilitates breakthrough thinking and stimulate fresh ideas

ò        Permits the problem to be pinned down accurately

ò        Ensures everyone clearly recognizes the problem

ò        Incorporates opinions of entire group

 2. Relations Diagram also known as Interrelationship diagram is a tool for finding solution to problems that have complex causal relationship. This helps to untangle and find the logical relations among the intertwined causes and effects. It is a creative process which allows for 'Multi-directional' rather than 'linear' thinking to be used.

Advantages of Relations Diagrams:

ò        Useful at planning stage for obtaining perspective on overall situation

ò        Facilitates consensus among team

ò        Assists to develop and change people’s thinking

ò        Enables priorities to be identified accurately

3. Tree Diagram is a technique for mapping out full range of paths and tasks that need to be done in order to achieve a primary goal and related sub goals. Such a diagram reveals in a simple way with clarity not only the magnitude of the problem but also helps to arrive at methods which are to be pursued to achieve the results. In other words, it serves the purpose of developing the essential means to achieve an objective or goal.

Advantages of Tree Diagrams:

ò        Systematic and logical approach is less likely that items are omitted

ò        Facilitates agreement among team

ò        Are extremely convincing with strategies

4. A Matrix Diagram consists of a number of columns and rows whose intersections are checked up, to find out the nature and strength of the problem. This will help us to arrive at key ideas and analyzing the relationship or its absence at the intersection and finding an effective way of pursuing the problem solving method. This enables conception of ideas on two dimensional relationship basis. The intersection points are also called "idea conception points".

Advantages of Matrix Diagrams:

ò        Enable data on ideas based on extensive experience

ò        Clarifies relationships among different elements

ò        Makes overall structure of problem immediately obvious

ò        Combined from two to four types of diagrams, location of problem is clearer.

5. Arrow diagrams are a network technique using nodes for events and arrows for activities for project planning, scheduling and monitoring. This is a very useful tool when we want to plan the activities of a known but a complex task or project. With the help of this tool we can workout an ideal project plan and also daily plan for not only to the main task but also for the other allied tasks and monitor their progress in an effective manner.

Advantages of Arrow Diagrams:

ò        Allows overall task to viewed and potential snags to be identified before work starts

ò        Leads to discovery of possible improvements

ò        Makes it easy to monitor progress of work

ò        Deals promptly with changes to plan

ò        Improves communication among team

 

6. The Process Decision Program Chart (PDPC) is a very useful and powerful method to overcome a problem or a goal to be achieved which are not familiar. With the help of PDPC we can map out all the conceivable events or contingencies that can occur in the implementation stage and also find out feasible counter measures to overcome these problems.

Advantages of Process Decisions Program Charts (PDPC’s):

ò        Facilitates forecasting

ò        Uses past to anticipate contingencies

ò        Enables problems to pinpointed

ò        Illustrates how events will be directed to successful conclusion

ò        Enables those involved to understand decision-makers intentions

7. Matrix Data Analysis is a multivariate analysis technique called 'Principal Component Analysis'. This technique quantifies and arranges data presented in a Matrix Diagram, to find more general indicators that would differentiate and give clarity to large amount of complexly intertwined information. This will help us to visualize properly and get an insight into the situations.

Advantages of Principal Component Analysis:

ò        Can be used in various fields (market surveys, new product planning, process analysis)

ò        Can be when used when Matrix diagram does not give sufficient information

ò        Useful as Prioritization Grid.
