Quality tools are highly demanding tools in the industries and the main objective of these tools is to identify and resolve the quality-related issues and thus helps in effectively solving the issues to anyone who are working in quality assurance or the process of improvement. Therefore the industry engineers have discovered most of the quality control problems which can be solved by following some key fundamentals. These key fundamentals are particularly known as Seven basic quality of tools. Thus in this article a comprehensive knowledge has been provided about the Quality tools and the basic seven quality tools.

What are Quality Tools?
Quality tools are mainly the types of methods of collecting, interpreting and organizing the data or the basic strategies of the process of production. Therefore these quality tools are mainly involved in various types of mediums which can help the businesses and organizations to determine any type of potential issues. Their causes and their important solutions.
7 Basic Quality tools for project management
There are top 7 basic quality tools which are mentioned below and these tools are used in project management to improve the efficiency of the tools and maintaining their quality.
Histogram
Histogram is another top quality tools for project management and the quality professionals are mainly tasked with analyzing and interpreting the behavior of the multiple group of data in an effort to manage the quality of the tools. They provide an easy way to identify the patterns and the outliers in data and determine the potential problems. Therefore this is the place where the quality tools are mainly used to improve the quality. Hence the histogram is mainly used to illustrate the frequency distribution of the data more clearly among multiple groups of sample which allows the individual to quickly and recognize the areas where the improvement is mainly needed.
Key Features:
- It’s used to display the distribution of a dataset.
- The histogram is used to represent the group while the height of the bar represents the frequency of the data within the similar group.
- It is mainly useful when breaking down the frequency of the data into the categories such as days, weeks and ages.
- It can quickly identify the outliners, patterns and also used to spot trends.
- It is also used for finding the central tendency of a set of data.
Scatter Diagram
Scatter diagram is another quality tool which is also known as scatter plot and this statistical tool is mainly used for showing the relationship between the two types of variables . The individuals can find out positive and negative correlations with this type of diagrams. Therefore by using this type of quality tool it helps the individuals to analyze the relationship between the training attendance and job performance the retail company which is used to make the important decisions which impact the business outcomes.
Key Features:
- This tool is used in representing job performance ratings to continue to improve reflecting the positive impact of training.
- The tool is mainly used to represent the two different numeric variables.
- This tools aids the project managers in analyzing and comprehending the relationship between variables.
- It represent the change in behaviour of effect when there is change in cause took place.
Control Chart
Control chart are the another important quality tools for project management and the graph of control chart are used to study how a process changes over time Therefore this tool helps in comparing the current to the historical control limit leads to conclusions about whether the process variation is consistent or it is unpredictable. These control chart mainly uses the central line to show an average or mean as well as an upper and lower line to show the upper and lower control limits which are based on the historical data.
Key Features:
- With the help of control chart individual use historical data which are collected from the current process and can be determine whether the current process is controlled by particular variation.
- By using control chart individual can save the organization time and money by predicting the process performance.
- It has a central line for the average, an upper line for the upper control limit and lower line for the lower control limit.
- It can also help to understand the variation which are always present in the processes.
Checksheets
The checksheets are another basic quality tools which are used for project management and it is used to collect data in real time at the location where the data is being generated. Check sheets are simple yet they are powerful qualitative or quantitive gathereing tool which can readily be analyze the useful information. Therefore these checksheets are mainly important in producing the raw data necessary for the defect problem solving and further used in statistical analysis.
Key Features:
- Checksheets are mainly used for collecting and organizing the data.
- It is also used for recording the data at a given time and place of the operation of interest.
- These checksheets are mainly designed for easy, quick and effective recording of the required data which can be qualitative and quantitative.
Fishbone diagram
The fishbone diagram is a type of visualization tool which is used for categorizing the potential causes of a problem. Therefore this tool is mainly used to order to identify the problem root causes. It is used for the root cause analysis, a fishbone diagram combines the practice of brain storming. It is useful in product development and trouble shooting processes which is used to focus a conversion around a problem. These fishbone diagram are made during a team meeting and drawn on whiteboard or flipchart.
Key Features:
- Fishbone diagram is mainly used to identify the possible causes of a problem.
- It is used to develop the product that addresses the issues within the current market offerings.
- This tool is used to avoid the reoccurring issues or the employee burnout.
- It is also used to reveal the bottle necks or the areas of weakness in the business process.
Pareto Chart
Pareto chart is mainly a type of graph which mainly indicates the frequency of the defects as well as the cumulative impacts. The Pareto charts are mainly useful to find the defects to prioritize in order to observe the greater and overall improvements. The pareto chart is a type of quality improvement tool which is based upon the pareto principle which is 80% of an outcome comes from 20% of the inputs. Therefore the pareto are the common tool which are used by the manufacturers to analyze the quality and the defect data by simply providing a simple visual representation.
Key features:
- The pareto chart are mainly useful to find out the defects to prioritize and improve the overall improvement.
- This tool is often used to represent the most common sources of defects.
- It is also used in problem solving , root cause analysis and processes to redesign.
Stratification
Stratification is a type quality assurance tool and it is used to sort the data, object and people into separate and different groups. It works by dividing the population into the homogeneous subgroups. Therefore in simple terms it is a way of breaking down a large number of population into a smaller groups. It is mainly used for determining whether there is a difference between groups or determining whether the problem is being investigated or determining whether the problems are same across various groups.
Key Features:
- This tool allows the individual to see the difference between groups.
- It provides a detailed information into why this type of problem exists.
- This tool is also helps to determine whether the problem is confined to a particular subgroup.
- The quality tool also helps to understand the results easily.

These 7 basic quality tools for the process improvements are the foundational in any quality improvement initiative. Therefore these quality tools are mainly versatile and it can be applied in multiple industries and the processes of the organizations to improve the quality of the products. Thus in this article a comprehensive knowledge has been provided about the Quality tools and the seven basic quality tools.
