What are the 7 Basic Quality tools?

The current global challenges make organizations adopt a systematic scientific approach to meet the challenges and invest the human resources to achieve the desired goals more efficiently and effectively. The tremendous development of our time has made organizations use many administrative, statistical and other tools for their success. Improve and develop performance and be judged here is the client through its perspective of quality and achieve its expectations and satisfaction with the product or service.

To achieve the overall quality of work there are seven tools for quality used in organizations, providing us with a lot of information to solve the problems of organizations and to find the desired solutions.

Seven quality tools

The Ishikawa plan: For the Japanese scientist Caro Ishikawa, who developed the technique in 1943, called the plot of cause and effect, or the shape of the fish's greatness (because the shape of the diagram is similar to the fish's greatness) The root structure represents all possible causes of influence. The head represents the outcome or impact, ie, the relationship between the results of an operation and the causes of the process. Each process is affected by an infinite number of elements.

 Please achieve A, and then focus on these reasons, to develop appropriate solutions and put forward proposals for improvement in the production process or service-and it can be used to organize a brainstorming session and directly produces ideas into useful categories, a structured and easy-to-read format and increases the practical knowledge and identifies the areas of data collection.

Pareto's analysis: is a creative way to look at the causes of problems; it helps stimulate thinking and organizing thoughts. But it becomes restricted if the problems that may be important and which may seem small at first but may become more important over time are removed. Through this analysis, the problems can be arranged in descending order from the most frequent to the least, that is, according to their importance and frequency.

 Through the Pareto map, the quality working group can identify the most important problems and inform them of the impact on quality and therefore focus on solving them first. The analysis is based on the Pareto principle, which is symbolized by Law 80/20. Through this technique, the quality improvement team can identify the important and influential few of the process, which is 20% of the causes, and thus can eliminate 80% of the problems of the process.

Pareto chart

Frequency distributions: is a graphical representation of the data and presented in a way that expresses the extent of deviation from the required specifications; to study the quality of their outputs or detect their defects. Thus, we can classify aggregated data into several categories and calculate their frequency.

 From this, it is possible to extract important information and indicators on the quality of the product or service, such as the average value of the data, the amount of data differences and their dispersion, and the judgment on the quality of the output and the performance of the process compared to the specifications specified by the client. Create relationships and interlinkages between events and get a brief idea of ​​the critical path of the process and the events involved in the critical path.

Histogram

The control maps are the main and best basis for performance monitoring and statistical monitoring of operations, so that continuous statistical analysis of changes in the process can be performed to monitor and control the quality of the product or service and improve the performance of the process. It is a graph showing changes and distortions in quality characteristics over time, which can distinguish between natural changes due to the underlying causes of the process and changes that are due to specific causes.

 Through which it is possible to determine whether the process is under statistical observation or that it is out of statistical control and is proceeding under other factors that adversely affect the quality of the product or service provided to the customer.

Scatter Diagram - Diffusion is a scatter diagram that analyzes the data of operations so that a potential relationship between two variables can be found. It is considered as a quality improvement tool available in the process improvement teams. The most important uses of this scheme in the field of quality and research and detection of the cause and effect relationship between two variables , To clarify the type of relationship between the two variables, and to know the strength of the link between them. They are used to design and document simple processes or programs and help to visualize what is going on and help to understand the process more and find flaws.

Scatter-Diagram

Flowcharts - Track: A diagram describing the flow of the process, steps and actions the product is going through or passing through. These maps are used to describe and track current processes, which allows for clarification of the key processes required and suggesting adjustments and improvements in the production and service process.

Flow Chart

Test lists: A technique used to collect, classify and record quantitative or qualitative data in groups with similar characteristics for each group in an organized manner. Through data collection and organization, the process-improving team can easily and easily analyze these data, helping to identify problems and make appropriate improvements to the process. .

All of these tools help to have great and different interests in the organization. Training courses on these tools should be included in the Organization's Organizational Orientation Program so that all staff can learn and apply these core tools in their field of work so as to enhance the efficiency and effectiveness of their work. BKH is one of the leading training institutions in this field.
