✏️ Transcript of the Video

Quality control is not just an afterthought, it is a crucial component of any business.

The seven quality tools listed in this video are all measures that you can take to keep your business in top shape and your customers happy with your quality work.


The 7 quality tools are:

1️⃣ Graph
Graphs can provide quick insights into the service quality of a company.
Graphs could be used in combination with other data sources to help identify trends and patterns in customers' perceptions about service quality.

2️⃣ Check Sheets
Check sheets are a simple, yet effective way to assure quality control.
A check sheet is a sheet of paper where you can organize and arrange things so they can be checked off.
They are used for quality control and to assure consistency.
For example, if you have a checklist for cleaning, you can go through the checklist and make sure that everything has been done.

3️⃣ Pareto Chart
A Pareto chart is a bar graph that shows frequencies in descending order.
It can be used to compare the relative frequency of different categories among different samples.
It is the simplest form of displaying quality control data.
You can identify how many specific defects are present in your product.

The Pareto principle, also known as the 80-20 rule, states that for many events about 80% of effects come from 20% of the causes

4️⃣ Cause and Effect Diagram
A cause and effect diagram is a tool for exploring different causal explanations for an effect.
A cause-effect diagram is a structured approach to explore the relationships between various variables.
The arrows in a cause-effect diagram represent the direction of causation, with the arrowhead pointing in the direction of causation.

5️⃣ Scatter Diagram
Scatter diagrams can be used to analyze and determine the quality of a product or service.
They can be used to identify any systematic errors that might occur in the process, and can also help you understand how changes in one variable will affect the other variables.

6️⃣ Histograms
Histograms are graphs that show the distribution of data.
They are used to identify patterns in data, evaluate the quality of a process, compare two populations to find similarities and differences, and more.

7️⃣ Control Chart
Control charts are used to monitor the variation of a process and its relationship to the mean.
A control chart is a graphical representation of data. It includes a trend line, upper and lower control limits, and points plotted on the graph.
Control charts help monitor processes such as manufacturing, construction, engineering projects, and quality assessments.

Conclusion
A quality tool is a valuable investment for any business. Quality Tools allow the business to be the best it can be, which in turn makes customers happy with their work.
