1. Cause-Effect Diagram

When a problem occurs, every single member of the time has a different idea about the initial cause, and it can be quite challenging to organize all opinions constructively. Cause-Effect Diagram, often called Fish Bone diagram since it sort of looks like a fish skeleton, catches all the ideas, and applies certain brainstorming methods to identify the potential root cause of the problem.

When using Cause-Effect, people remain in the context of ”why” while stating a question. By that, you will get adequate assistance with brainstorming because we all know that each problem has its own answer. The idea is to match the problem statement by the entire team and figure out the ”head” of the fishbone.

2. Flowchart

Some readers might recall using Flowchart earlier. It is a design tool that traces both workflow methods and algorithms in different areas. People use it for describing organizational arrangements, document processes, login, etc.

With Flowchart, you will be able to enable the classification of flows of cases within the system, which is a way to measure the process and present information in an understandable and easy-to-grasp manner.

3. Scatter Diagram

Good news to graphical illustration fans! In case you need to figure out the correlation between two variables and love graphical illustrations that are easy to understand, then Scatter Diagram is right for you. It is a very viable tool used to point out the cause and effect, using the variable to describe the wide specter of reasons and effects possible.

Note that it keeps one variable as sovereign and conditions the other, which is viewed as a ”Scatter Plot”. The user-friendly nature of it makes it easy to accurately see the correlation between the variables and note that if the points are dropping, there is probably no correlation between them.

4. Pareto Chart

To sum up, a group of data may be tied to different parameters like cost, errors, time, etc. A Pareto chart uses a Bar and a Line table. Simply a Bar table, and a Line table, where the bars represent the values in a diminishing manner.

For instance, the highest bar value will be on the left instead of the lowest on the right side. To measure the occurrences, follow the vertical line on the left side. You can link it to any parameter you want to measure, like cost or errors.

5. Histogram

To easily access intense statistical features such as statistical distribution, data dispersion, and central tendencies, use Histogram. It is highly suitable for those who are seeking to identify categories with higher frequency.

It is important to add that it can be used in different applications to define the assets that will be utilized in the project work. The specialty of Histograms is breaking down the data frequency into categories of your choice, such as days of the week, age, or any type of data that can lay out in chronological and numeric order.

6. Stratification

If you are looking for a quality assurance tool used to sort data and objects, say no more. Stratification is right there to let you separate data using stratification and discover patterns that are otherwise hardly visible.

Regardless of what you are working on, whether it is products, materials, or else, this tool’s analysis enforces the understanding of your data before, while, and after collection.

7. Control chart

Another tool that promises quality improvements and lets professionals easily state whether some process is predictable or not is the Control chart.

It makes it easy for its users to recognize factors that influence potential defects or lead to variations. What it does extraordinarily well allows which processes are controlled and which are under the influence of certain variations.


The article attempted to depict the fundamental quality control tools suitable for any software business. As you might have noted, each tool comes with its own approach, way of delivering the data, and its own set of advantages on certain occasions.
