Measurement tools and quality The ability to make accurate measurements often depends on the tools we have.
The ability to quickly and efficiently identify and resolve quality-related problems is essential for anyone working in quality assurance or interested in process improvement.
With essential quality tools, you can easily manage the quality of your product or process, no matter what industry you serve.
Here's a closer look at some of the essential quality control gauges.
Measurement and quality tools
tape measure
The ability to measure dimensions will be critical to almost every project imaginable.
It is important to keep proper tools around the workshop to find dimensions, including a reliable tape measure.
The instrument you are using must provide measurement marks for both imperial and metric distances. Unlike some other tools used for more accurate readings, the tape measure is useful for larger projects as there is a little more room for error.
Rulers, levels, squares, and protractors
Many situations require more accurate measurements than a standard tape measure can provide.
When this need arises, there are many examples of tools you can use to complete the task, including rulers, compasses, and protractors.
Using the right tool for the job ensures that your projects stay square and flat.
caliper
A caliper is an instrument used to measure the distance between opposite sides of an object.
Calipers are an essential quality control measure in the workshop because they can help find the dimensions of round or irregular objects.
Today, there are different types of calipers, including some that give you a digital readout of the measurements.
the scale
Just like there are many different types of calipers, there are also different gauges available as well.
These scales help find the weight of what you're working with, ensuring that your project can handle the weight you intend to put it on.
Engineers and Architects also use a special type of gauge finder to detect the linear scaling of whatever shape it's tracking and convert the numbers into a gauge for your project.
stratification
Stratification analysis is a quality assurance tool used to sort data, things, and people into separate, distinct groups.
Separating your data with stratification can help you determine its meaning, revealing patterns that might not otherwise be visible when they are grouped together.
Whether you're researching equipment, products, shifts, materials, or even days of the week, stratified analysis allows you to understand your data before, during and after it's collected.
To get the most out of your stratification process, consider information about your data sources that may affect the final results of your data analysis.
Be sure to set up your dataset so that information is included.
graph
Quality professionals are often tasked with analyzing and interpreting the behavior of different sets of data in an effort to manage quality.
This is where quality control tools like histogram come into play.
A histogram can help you clearly and accurately represent the frequent distribution of data between different sample groups, allowing you to quickly and easily identify areas for improvement in your processes.
With a structure similar to a bar graph, each bar within the graph represents a group, while the height of the bar represents the frequency of data within that group.
Flowcharts
Flowcharts are visual representations of a process, where the shapes represent the steps, outputs, or decisions to be made during the execution of the process.
Use a flowchart to document the process, keep steps concise and use subject matter experts to create
Flowchart.
Ask partners who are not familiar with the process to use the flowchart to carry out the process.
This helps validate the flowchart.
Look for loops in the process. A loop is a series of steps that can be performed repeatedly and cause a delay in completing the process.
Also check for bottlenecks in the process, bottleneck is the part of the process in which the output is much slower than the input.
Use flowcharts to isolate problems in the process, then work with stakeholders to remove problems.
Balanced scorecard
A balanced scorecard is a tool that provides a view of an organization from a financial, customer, and business process perspective, and from a learning and growth perspective. The financial perspective is that of the shareholders.
This perspective raises questions such as what is the ultimate return? The customer perspective asks if customers are satisfied.
Business operations question how effective operations are in meeting the requirements of customers and shareholders. Learning and Growth examines how an organization manages change and improvement, not only for products and services, but also for employees.
Where did quality tools originate?
The Seven Quality Tools were originally developed by Japanese engineering professor Kaoru Ishikawa.
Implemented by the Japanese Industrial Training Program during the country's post-war period it turned to statistical quality control as a means of quality assurance.
Their goal was to implement basic, easy-to-use tools that workers from diverse backgrounds with diverse skill sets could implement without extensive training.
Today, these quality management tools are still considered the gold standard for troubleshooting a variety of quality issues.
They are frequently implemented in tandem with the most widely used process improvement methodologies today.
