What Is Six Sigma?

Six Sigma is a set of quality improvement methodologies that focus on reducing process variation. Sigma is a statistical term that refers to the amount of variation in a given process. 

Six sigma is the level of excellence achieved when there are less than 3.4 defects per million opportunities. When applied correctly, Six Sigma can help your company reduce waste and more efficiently deliver on high-priority projects. 

Your defect rates will decrease, giving you a competitive edge. But the benefits of this business strategy go beyond operational excellence.

A common misconception about Six Sigma is that it is solely about quality assurance (QA). In reality, Six Sigma is a comprehensive business methodology that focuses on all aspects of an organization’s business. This includes the sales funnel, marketing strategy, customer service, and operations.

Importance of Six Sigma

Six Sigma is a process that helps companies identify and eliminate waste in their business processes. Unfortunately, many businesses don’t know that they’re missing out on this powerful methodology. 

The Six Sigma process is based on a few key principles, which are:

Define the Business Challenge

Businesses must first define the process challenge they are trying to solve. Once they’ve clearly defined the challenge, they must identify the business impact of not solving the problem. This will help them prioritize the business challenge and determine which methodology to use.

Break the Challenge into Pieces

Once the business challenge is defined, the team must break it down into smaller pieces that can be more easily solved. This is commonly referred to as the “root cause analysis.” For example, if the business challenge is to improve lead generation, the team must break the challenge down into smaller pieces such as identifying lead sources, closing the sale, etc.

Use the Right Tool

The team must choose the best methodology to solve the problem at hand. While Six Sigma is often associated with the six sigma methodology, there are many other methodologies that can be used as well.

Build a Culture of Continuous Improvement

Once the business challenge has been identified, broken down into smaller pieces, and solved with the appropriate methodology, continuous improvement must follow. Companies must approach project management with a “continuous improvement mindset” to ensure that there are no “quick wins.” This will ensure that the company is always improving.

How does Six Sigma Work?

Six Sigma is a quality improvement methodology that has been adopted by businesses across the globe. The Six Sigma approach aims to improve the quality of products and services by identifying and eliminating defects. 

Six Sigma has been shown to be an effective way to improve the quality of products and services and has been credited with helping businesses to improve their bottom line.

There are many different ways to approach Six Sigma, but the basic philosophy is the same: to identify and eliminate defects. The approach is based on the statistical concept of variation, and the goal is to reduce variation in the process so that it is within acceptable limits.

There are Six Sigma tools and techniques you can use to help achieve this goal, and these tools and techniques are used to help identify and eliminate defects. The statistical tools and techniques used in Six Sigma are divided into five main categories:

Define: This is the first stage of Six Sigma, and it is where the problem is defined and the goals are set.

Measure: The second stage of Six Sigma is where the data is collected and analyzed.

Analyze: The third stage of Six Sigma is where the root cause of the problem is identified.

Improve: The fourth stage of Six Sigma is where the solutions are implemented and the results are monitored.

Control: The fifth and final stage of Six Sigma is where the process is controlled to ensure that the improvements are maintained.

Each of these stages is important in the Six Sigma process, and each stage has its own set of tools and techniques. The tools and techniques used in each stage will vary depending on the particular problem you’re addressing.

There are many different Six Sigma certifications available, and these certifications can be obtained from a variety of different organizations. These certifications are not required to practice Six Sigma, but they can be helpful in demonstrating your commitment to quality.

5 Key Principles of Six Sigma

Understand and Document the Business Process 

Every company has a unique business process for delivering their product or service to customers. For this reason, it’s important to first understand and document your business’s process. This will help you identify where the process may be flawed or broken.

Identify Problem Areas and Sources of Error

Once the business process has been understood, the team must identify problem areas and sources of errors throughout the business process. The team can do this using a “fishbone diagram.” 

To start, write your business process on a large piece of paper. Next, break the business process up into smaller business functions. Then, write down all the potential causes that could negatively impact each function. This will help you identify error sources and problem areas that need to be fixed.

While Six Sigma is often associated with the six sigma methodology, there are many other methodologies that can be used as well. – Build a culture of continuous improvement – Once the business challenge has been identified, broken down into smaller pieces, and solved with the appropriate methodology, continuous improvement must follow. Companies must approach every project with a “continuous improvement mindset” to ensure that there are no quick wins. This will ensure that the company is always improving.

Six Sigma Methodologies

There are many different Six Sigma methodologies that can be used to solve business challenges. Companies can choose the methodologies that best suit their business needs. Some of the most common Six Sigma methodologies include:

Design for Six Sigma

Design for Six Sigma (DFSS) is a methodology that focuses on product design and development. Companies that use DFSS will initially design their product or service to meet customer needs and expectations. 

Then, they will use data to identify and eliminate sources of error throughout the design process to meet their quality standard.

Define, Measure, Analyze, and Improve

This methodology is the most basic yet effective form of Six Sigma. It follows the “define, measure, analyze, and improve” process and can be used to solve many business challenges. This methodology is often used for minor issues and quick wins.

Benefits of Six Sigma

As mentioned above, there are many benefits to implementing a Six Sigma program or methodology. Some of the key benefits include:

Increased Efficiency

One of the most obvious benefits of Six Sigma is that it can help your company become more efficient. When you implement Six Sigma, you will eliminate waste, increase efficiency in all business functions, and create a streamlined process that is easier to manage. This will help you take on more projects, reduce costs, and increase company revenue.

Initiate

At the start of the process, you and your team will select a project that you want to optimize. You’ll also determine what’s causing the project to be inefficient.

Identify

The next step is to identify the root causes of inefficiencies that are preventing you from completing projects on time and within budget. You’ll conduct an analysis of your project’s data to identify problem areas.

Measure

After identifying issues, you’ll measure them to determine the scope of the problem. You’ll use measurements to determine which areas need the most attention.

Improve

The final step is to improve your project. You can do this by applying Six Sigma tools and concepts to solve issues that are impeding project completion.
