In a fast-paced world, it’s easier than you think to let things slip by. Several things can go wrong on a project. For example, the data used for a project was inaccurate, your team’s deadline has come and passed, or your product isn’t sitting right with its target demographics. To ensure success, many use the Six Sigma methodology.
Particularly when you’re working hard on developing a product for your business, the Six Sigma process can come in handy. After pouring a ton of man-hours into the development of a product, chances are that you really don’t want it to fail. But how do you ensure that a product doesn’t have any defects and won’t interfere with your bottom line?
What Is Six Sigma?
The Six Sigma methodologies are a series of processes and quality improvement initiatives that aim to rid a business’s product development cycle of defects and waste. It’s pretty ambitious, but Six Sigma is a tried and true method of what’s known as a ‘continuous improvement’ methodology.
The name Six Sigma is taken from statistics and refers to the process capability of quality control, which is extremely important to the Six Sigma methodology.
Six Sigma’s methodologies are based on two concepts: DMAIC and DMADV. DMAIC is used to improve older, more established business processes, while DMADV is usually applied to newer business processes.
DMAIC
DMAIC is an acronym that refers to a series of steps taken to improve a process. It consists of define, measure, analyze, improve, and control.
To implement this system, a business professional must:
- Define a system
- Measure aspects and collect data
- Analyze the data
- Improve the process
- Control the future process
By clearly stating its goals, a business team can keep an eye out for any problematic features that may arise in its developmental process.
DMADV
Like DMAIC, DMADV is also an acronym. It refers to how project managers and team members at a business must define, measure, analyze, design, and verify. These steps are broken down below.
- Define. What are the goals of the project or product?
- Measure. Team members need to measure product capabilities and manage risks.
- Analyze. Analyzing pertinent info and data is crucial to improving business processes.
- Design. Create a new design. Scrap what didn’t work before and design something that does based on the data collected.
- Verify. Checking your new design means implementing the processes and seeing if your intended business improvements come to fruition.
What Is Six Sigma Used For?
So what are the basic underlying principles of Six Sigma? Let’s break it down.
- Process Improvement. Although nothing is perfect, the point of the Six Sigma process is to help you get as close to perfection as possible. Using DMAIC and DMADV, Six Sigma is a great way to try to improve your business’s output by reducing defects and waste.
- Data Measurement and Data Analysis. Data can be used to determine the success of nearly everything. Each product that you use in your daily life has gone through many cycles of quality control to ensure it’s fulfilling its intended uses. By harnessing the power of data, Six Sigma can be used to continuously improve business processes.
- Product Improvements. What happens when a product fails? It’s bound to be a disappointment, but it is also an opportunity to review mistakes and improve upon them. Using data as mentioned earlier, project managers can scrap ineffective designs and spearhead new experiments and ideas.
- Increase Customer Satisfaction. Overall, this is the ultimate goal of the Six Sigma process. By minimizing waste and variation, products and services are more likely to achieve success with customers.
Six Sigma Belt Levels
There are various levels of Six Sigma methodologies. Modeled after the karate belt system, a Six Sigma belt level denotes an individual’s level of expertise within the method.
Let’s look at the belts and what they mean for business professionals.
White Belt
As you may have guessed, the white belt shows someone has a fundamental grasp on the Six Sigma methodologies. This individual hasn’t taken their Six Sigma skills to the next level with a Six Sigma certification or online course.
Yellow Belt
Those with a yellow belt have an understanding of basic and intermediate concepts within the Six Sigma framework. Yellow belt professionals are familiar with core Six Sigma concepts and can deliver them on a wider scale.
Yellow belt professionals may have attended a few courses or seminars to improve their Six Sigma skills.
Green Belt
Six Sigma green belts have considerable knowledge of what goes into implementing the two Six Sigma methodologies. They can effectively change the course of a business’s development cycle.
Project leads and support staff should ideally have at least a Six Sigma green belt certification.
Black Belt
As with the karate belt system, the Six Sigma black belt signifies an impressive level of mastery in Six Sigma implementation. It takes extensive Six Sigma training to become a black belt.
Those looking to earn a Six Sigma black belt need to get certified and learn how to assist their team members in the development process. Those who have a black belt will know a lot about statistics, including standard deviations, distributions, case studies, and standard error. A black belt can lead a team effectively and implement successful business strategies.
After the black belt, there are also more advanced levels of Six Sigma.
Learning Six Sigma
Learning Six Sigma is useful whether you want to become a black belt, or just want to learn a little more about how to implement effective strategies that minimize defects.
How Long Does It Take to Learn Six Sigma?
Depending on the program, it could take anywhere from one to three months. This is the standard length for many Lean Six Sigma certification courses.

Let’s look at the steps you should take to learn Six Sigma.
- Enroll in a class. There is no shortage of great online courses and Six Sigma training to take advantage of. These various classes give you the building blocks you need to learn the Six Sigma methodologies.

- Earn training at various belt levels. Your learning journey is never quite over. Once you have mastered a yellow belt or green belt, why not take it to the next tier? With higher Six Sigma belts, the more you can do with the qualification. For example, at the higher black belt levels, you can become a Six Sigma mentor and program lead.
