7 quality tools examples

There is a limitation to draw a histogram. You should have enough data to draw and drive the results. A Pareto chart is a bar graph of data showing the largest number of frequencies to the smallest and a cumulative percentage, as shown in the graph below.

When you look at the number of defects from the largest to the smallest occurrences, it is easy to prioritize improvement efforts. To draw a Pareto chart is quite simple. The major part is collecting the right data. Pareto Chart Template. In the below chart, I need to find the major root cause of my quality issues related to the steel industry during the casting process. As explained in Histogram, the Pareto charts should not be mixed with those.

Pareto charts have a cumulative percentage curve as well, categorized from high to low level. This is one of the best tools to understand the fluctuation in a process over time. It is also called a run chart or a time series plot. It helps to find when and how o take action on set limits.

Contro charts help to find the consistency of any process. First of all, we have to get the calculations for that particular process. You can download the Control Chart Template. You can see in the below graph; a run can help you find consistency in your process.

We set the Control Limits to not bother about all the stuff of our process. A scatter diagram or scatter plot is also a statistical tool.

It uses variables like dependent variables on Y-Axis and Independent Variable on X-axis plotted as dots on their common intersection points. A scatter diagram is used to find the root cause of any problem, but only if there is any relationship. You can download here the Scatter Chart Template. The above graph explains a positive relationship with the time a village is getting populated. These relationships can be linear, exponential, quadratic, logarithmic, polynomial, etc.

It is not an easy question, but if your concepts are clear enough, you will enjoy using all the tools. Answer: Experience, and if you know about the tools insight well, you can easily understand the process. What does PMP stand for?

Pareto chart is having bars graphs and line graphs where individual factors are represented by a bar graph in descending order of their impact and the cumulative total is shown by a line graph. Scatter diagram or scatter plot is basically a statistical tool that depicts dependent variables on Y — Axis and Independent Variable on X — axis plotted as dots on their common intersection points.

Very purpose of scatter Diagram is to establish a relationship between problem overall effect and causes that are affecting. The relationship can be linear, curvilinear, exponential, logarithmic, quadratic, polynomial etc.

Stronger the correlation, stronger the relationship will hold true. The variables can be positively or negatively related defined by the slope of equation derived from the scatter diagram. Control chart is also called as Shewhart Chart named after Walter A. Shewhart is basically a statistical chart which helps in determining if an industrial process is within control and capable to meet the customer defined specification limits.

The very purpose of control chart is to determine if the process is stable and capable within current conditions. In Control Chart, data are plotted against time in X-axis. Control chart will always have a central line average or mean , an upper line for the upper control limit and a lower line for the lower control limit.

These lines are determined from historical data. This is a graphical representation to evaluate the data. This practice was first founded by Japan and implemented in a training program. Later found the improvement of quality in complex issues industries of the entire country, eventually using quality spreader all over the world.

This is used in detailing various phases of the six sigma process, which is the continuous improvement process in the industry. The effective use of 7 quality tools helps in maintaining the standards in quality and service. This helps in identifying the issue in the production process, controls, and provides a solution to mitigate future defects. These Quality tools are used to map the quality and provide them with a continuous improvement in the production process.

All the 7 quality tools are detailed and studied under the Lean Six Sigma Master study, which teaches quality in production. Scrum is an Agile product quality development and implements increment practices. This is also called a fishbone chart or Ishikawa diagram. This is used to identify the cause and effect of the problem and re-arrange and implement ideas strategically. It is a sheet prepared in a structured way.
