This article provides an in-depth look into how Six Sigma's powerful, data-driven methodology can transform your approach to work management.
Understanding Six Sigma
To better understand what role Six Sigma plays in improving business processes, it's a good idea to dive into the most important Sigma concepts.
In general, Six Sigma is a methodology that aims to improve the quality of business processes, products, and services by reducing defects and variation. In the Six Sigma method, you operate on three levels:
Using statistical tools and techniques.
Identifying and eliminating the root causes of problems.
As a result, Sigma's processes improve customer satisfaction, increase productivity, and reduce business costs.
That's the official definition, so let's take a look at Six Sigma in a more friendly way. Six Sigma implementation may not be easy for beginners. But once you know how to do it right, it'll be a piece of cake.
Definition of Six Sigma
Six Sigma, initially developed by Motorola in the 1980s, has become a globally recognized set of techniques and tools for process improvement. At its core, Six Sigma is a data-driven approach that aims to eliminate defects and reduce variability in any business or lean process.
The ultimate goal of Six Sigma is to deliver near-perfect products or services to the end user. In more advanced terms, this quality improvement methodology strives for a statistical measure of 3.4 defects per million opportunities, symbolized by the Greek letter sigma (σ). But that's a definition for scientific minds.
Principles of Six Sigma
Understanding the principles of Six Sigma is crucial to apply them effectively in high-level management. These principles form the bedrock of Six Sigma's methodology and provide a framework for achieving process improvements.
Here are the main tenets of Six Sigma:
Customer focus: Six Sigma revolves around understanding and meeting customer requirements. It stresses that quality is defined by the customer, and thus, all improvements must contribute to meeting or exceeding customer expectations.
Data-driven decision making: Six Sigma leverages statistical analysis to quantify process performance, identify issues, and validate the effect of changes. This principle eliminates guesswork and hunches, allowing decisions to be made based on solid data.
Process optimization: this principle emphasizes that quality must be built into processes. You can achieve quality improvement by identifying and removing the causes of defects, and minimizing irregularities in processes.
Proactive management: Six Sigma encourages proactive problem-solving and process improvement. Rather than waiting for issues to emerge and then reacting, Six Sigma promotes the anticipation of problems and the implementation of preventive measures.
Collaboration: Six Sigma recognizes that process improvement is a team effort. It necessitates the involvement and collaboration of everyone within the organization, from top-level management to frontline staff.
In general, In Six Sigma, customer satisfaction is the priority towards which you're aiming. And all that happens along the way is supposed to bring you closer to that satisfaction.
When to Use Six Sigma Methodology?
Six Sigma methodology is best utilized in situations where there is a need for process improvement, defect reduction, and achieving high levels of quality and efficiency. If you wonder whether Six Sigma is good for your business, you can ask yourself whether things go as planned or if you need to enforce changes.
Is there a high defect rate in your processes? Do the outputs lead to inconsistent results causing significant variation? Are there any financial problems? Are processes in your company long, tiresome, and ineffective?
In general, if you're facing some organizational obstacles, or need to revamp current practices, then Six Sigma is for you.
Six Sigma and Lean Six Sigma
You may be familiar with the two types of methodology. Although they both aim at quality improvement, they have some key differences. Lean Six Sigma evolved by combining Six Sigma principles with Lean manufacturing concepts, which originated from Toyota's production system.
Lean Six Sigma method also aims to reduce defects and variation. It goes a step further by targeting process waste and inefficiencies to achieve optimal performance. Lean principles aim to eliminate activities with no value and streamline processes.
In addition to the statistical tools from Six Sigma, Lean Six Sigma employs various Lean tools like Value Stream Mapping, 5S, Kanban, and Kaizen to identify and eliminate process waste and improve flow.
So, the main difference between Six Sigma and Lean Six Sigma is that the latter focuses on reducing defects and process variation, while Lean Six Sigma also targets process waste and efficiency to maximize customer value.
Is Six Sigma Better Than Lean Six Sigma?
Whether Six Sigma is better than Lean Six Sigma depends on several factors. To choose the right one for your projects, you should consider four main elements:
Organizational goals: you have two options—the first one is to improve product or service quality and reduce defects. Here, Six Sigma might be the more appropriate choice. On the other hand, if you want to achieve efficiency gains and minimize waste but keep quality, Lean Six Sigma will be better.
Industry and process type: different industries and processes have distinctive requirements. Some may benefit more from the statistical rigor and defect reduction focus of Six Sigma, while others may find Lean principles more applicable to their operational challenges.
Project scope: large, multifaceted projects might benefit from a Lean Six Sigma approach to streamline the entire process. Smaller, specific problem-solving efforts may find Six Sigma's statistical tools more suitable.
Available resources and expertise: consider the organization's existing skill sets and resources. If your employees are already familiar with Lean principles or statistical analysis, it might make sense to leverage that knowledge when selecting the methodology.
In practice, many organizations find value in combining both methodologies, employing Lean principles to identify and eliminate waste, and Six Sigma tools to achieve quality and defect reduction. This integrated approach, often referred to as Lean Six Sigma, provides a comprehensive toolkit for process improvement.
Above all, to decide which of the quality management methods is best for you, it's crucial to consider your organization's specific needs and objectives because each approach brings unique strengths to the table.
Do I Need Six Sigma Certification?
Six Sigma certification is a formal recognition of the knowledge and expertise in Six Sigma methodologies. It signifies that you've successfully completed training and demonstrated proficiency in applying Six Sigma techniques and tools. Is it necessary? It depends.

The Process—How to Apply Six Sigma
The Six Sigma process may seem complex. However, it comprises several easy-to-follow steps that will help you in creating process maps
DMAIC in Six Sigma
The DMAIC model, standing for Define, Measure, Analyze, Improve, and Control, serves as a roadmap for process improvement in Six Sigma. This structured approach helps to optimize their management process. There are five phases to follow:
1. Define: the first step involves defining the problem or project goal. This includes understanding the customer's needs, setting objectives, and identifying the process that needs improvement.
2. Measure: in this phase, you collect the baseline data to measure the current performance of the process. This gives a clear picture of the existing situation and serves as a benchmark against which you can measure improvements.
3. Analyze: you can now analyze the data you collected in the measure phase to identify the root causes of defects or issues. You can use various statistical tools and techniques to understand the relationship between different process variables.
4. Improve: based on the analysis, you develop solutions and test them to address the root causes of the identified issues. The goal here is to eliminate or reduce defects and improve process performance.
5. Control: in the final phase, you standardize the improved process, and implement control plans to ensure that the improvements are sustained over time. This involves monitoring the process and making necessary adjustments to maintain performance.
Existing Process Improvement vs. New Processes
When you apply the Six Sigma process, you can also choose the DMADV phases. DMADV is a bit different than DMAIC. It stands for Define, Measure, Analyze, Design, Verify.
DMAIC is used to improve existing processes that have problems or need enhancements, while DMADV is used to create new processes or products from scratch, ensuring they meet customer requirements.
Both methodologies are essential components of the Six Sigma toolkit and are chosen based on the nature of the project and the specific improvement goals.
