Quality control is always a concern for companies. When there is a quality control problem, it can cause a company to lose customers and have a bad reputation. If you are looking for a solution to quality control problems, the 7QC Tools is the perfect solution. These are quality control tools that provide a solution to any quality control problem by quickly and easily solving the issue.
7 QC Tools Overview
The seven quality control tools are the following:
1. Flow Chart
A flow chart is a diagram that uses symbols to represent the steps in a process. The symbols are connected by arrows that show the order of the steps.
2. Fishbone diagram:-
A fishbone diagram, also known as an Ishikawa diagram, is a graphic tool used to help organise and analyse causes of problems. The diagram is shaped like a fish skeleton, with the head and tail of the fish representing the beginning and end of the problem, and the bones representing the causes.
3. Check sheet:-
A check sheet is a simple document that lists the steps in a process. It can be used to track the progress of a project or to ensure that all the steps in a process are completed.
4. Pareto chart :-
A Pareto chart is a graphical tool used to display the relative proportions of occurrence of different values. The y-axis of a Pareto chart represents the frequency or percentage of occurrence of the values, while the x-axis represents the rank order of the values.
5. Scatter diagram:-
A scatter diagram is a graphical tool used to display the relationship between two variables. The axes of the graph represent the two variables, and the points on the graph represent the values of the two variables for individual data points. A line can be drawn through the points to illustrate the overall trend of the data.
6. Histogram:-
The histogram is a graphical representation of the distribution of data. The x-axis represents the different values, and the y-axis represents how many data points fall into each category.
7. Control chart:-
A control chart is a graphical display of data that is used to identify and quantify the factors that affect a process.
Control charts are used to determine whether a process is in control and to identify the cause of any deviations from the process specification.
How does the 7 QC Tools work?
The 7 QC tools work by inspecting and measuring product or process quality characteristics. The tools are used to identify and correct problems so that the product or process meets requirements. The tools are also used to track and trend quality data to ensure continuous improvement.
Conclusion:-
In conclusion, the 7QC Tools is a great way to quickly and easily solve quality control problems. It can help you identify and fix issues before they become bigger problems. If you're looking for a tool that can help you improve the quality of your product, then the 7QC Tool is definitely worth considering.

Flow Chart is a diagram that uses graphic symbols to depict the nature and flow of the steps involved in a process. It is used to understand various processes involved and the sequence of execution of the process.
If you are new to a process and you need come clarity about what are the process are involved and what is the sequence of the process that is happening the right tool to be used for this is Flow Chart.
For an effective problem solving we need to understand the process flow to decide where to start the troubleshooting.
A simple example is given below
The flow chart above gives us a clear picture what is the process involved between the raw material receipt and final machined components sent to assembly. It is easy to interpret the actual process with the flow chart and understand the deviations so as to take appropriate decisions in the problem solving process.
There are various symbols used in drawing a flowchart. A list of symbols and the application is explained below.
We believe the content posted above has helped you to learn the basics about Flow Chart. We would be glad to hear your comments in the comments section below.
