Digital transformation has been the most current tagline of this decade. New tools and technologies are supporting this digital transformation journey of big and small companies as they get the best output in a fast-paced competitive environment. But this digital transformation requires an independent technology implementation to resolve the problems in troubleshooting or production process. Even though digital transformation accelerates the company’s growth, it has to be supported by the management methodologies of business transformation and quality control.
Considering all these requirements, an American-based company “Motorola” built the concept of a quality management process in 1986. Over time, it has been developed into a theory of methods and principles intended for business transformation using a defined process. That theory is “Six Sigma.” Six Sigma is a group of management techniques and tools built to enhance the capability of the business process by minimizing the possibility of error. It is the data-driven approach that eliminates and reduces defects and maximizes profits. In this Six Sigma technique blog, you will master all the essential and popular six sigma techniques that are implemented in leading organizations like Amazon, Atos, Bank of America, BAE Systems, etc.

Six Sigma Techniques combine several robust tools for use in the constant enhancement of programs and projects. There are several useful quantitative and qualitative techniques that are included in the Six Sigma toolbox. While several methods are utilized for a particular purpose, critical and essential techniques are commonly utilized in every six sigma project.
Six Sigma techniques are used to assess every step of the business process. They offer methodologies to enhance the business structure's efficiency, the process's quality, and the bottom-line profit. Six Sigma techniques emphasize restricting the fluctuation of the business processes and quality management of the process by deploying problem-solving statistical methods.
The Six Sigma steps for process enhancement, also called DMAIC, are straightforward and direct.
Step 1: Define the Problem: Build the problem statement, project charter, process map, customer requirement, and goal statement.
Step 2: Measure the Process: Gather the data on the current issues and performance. Check whether the data is secure and upgrade the project charter as required.
Step 3: Analyze the reason for the issues: Review the process and the data that was gathered, show the data, investigate it, confirm the reason for the issues, and continue upgrading the project charter as required.
Step 4: Control: Elaborate the process, continue monitoring, and utilize discoveries elsewhere in the business, if feasible.
Step 5: Enhance the process: Determine the solutions for fixing the issues and create the process maps for new solutions. Run the steps for implementing the latest fixes and measure enhancement.
DMAIC is the standard approach utilized by Six Sigma professionals. Six Sigma utilizes data-driven management utilized for enhancing and optimizing business processes. The integral framework is a strong customer focus and strong use of statistics and data. The six Sigma process of the DMAIC method has the following phases:
Each of the above phases will have the following steps
The six Sigma process starts with the customer-centric methodology:
Step 1: The business problem is specified from the customer's point of view.
Step 2: Goals are fixed. What do you want to get? What are the resources you will utilize to achieve your goals?
Step 3: Map the process. Check with the shareholders that we are on the appropriate track.
This phase emphasizes the measures of the project and the tools utilized in the measurement. How can we enhance? How can we quantify this?
Step 1: Measure the problem in the numbers or with the supporting data.
Step 2: Specify the performance yardstick. Set the limits for “Y.”
Step 3: Asses the measurement system to be utilized. Can it help you get your output?
This phase analyzes the process of finding the influencing variables.
Step 1: Evaluate whether your process is effective and efficient. Does the process help you achieve what we require?
Step 2: Measure your objectives in numbers. For example, decrease the defective goods by 20%.
Step 3: Determine the variations through the historical data.
This phase inquires how the modifications in “X” affect “Y.” In this phase, you will identify how we can enhance the process implementation.
Step 1: Find the probable reasons. Test to discover which of “X” variables found in Process III influence “Y.”
Step 2: Find out the relationships between variables.
Step 3: Setup “process tolerance.” specified as the exact values that particular variables can include and yet fall within the tolerable boundaries, for example, the quality of the product. We can get the process tolerances through tools like validation sets and robust optimization.
In the last phase, we find that the performance objective discovered by the prior phase is implemented and that the designed enhancements are acceptable.
Step 1: Validate the measure system to be utilized. https://go.microsoft.com/fwlink/?LinkId=2085792&lcid=1033
Step 2: Setup the process capability. Is the goal being achieved? For instance, will the objective of decreasing the defective goods by 20% be achieved.
Step 3: Once the prior setup is met, run the process.
Six Sigma utilizes a mixture of data analysis and statistical tools like process design and mapping and demonstrates quantitative and qualitative techniques to get the required outcome.
It is the essential process of the problem-solving method and is frequently used in the “enhance” stage of DMAIC methodology. It is the required process before anyone begins utilizing any tools. Brainstorming includes vigorous ideas and creative approaches to solving a problem using intensive group discussions.
This technique enables us to find out the root cause of the problems in consideration and is utilized in the “analyze” phase of the DMAIC cycle. In the 5 Whys techniques, the question “Why” will be asked again and again, ultimately leading to the core issues. Even though “five” is a rule of thumb, the exact number of questions can be fewer or greater, whatever it wants to get clarity.
This is the mechanism utilized for capturing the “customer voice” or the customer feedback in either external or internal ways. This technique is intended to give the customer the best services and products. It grabs the changing requirements using indirect and direct methods. The voice of customer methodology is utilized in the “define” stage of the DMAIC methodology, generally to specify further the problem to be handled.
Benchmarking is the technique that utilizes a set standard measurement. It includes making comparisons with other enterprises to get an independent appraisal of the provided situation. Benchmarking can consist of comparing essential processes or departments within the business, comparing the same work areas or functions with the industry leaders, or comparing the same services and products with the competitors.
This technique has its origin in the Japanese principles of workplace energies. The 5S System is intended to remove waste and eliminate the problems from ineffective tools, resources, or types of equipment in the workplace. The five steps utilized are: seiso(shine), Seiri(Sort), Seikestu(Standardize), Seiton(Set In Order), and Shitsuke(Sustain).
This name comes from the Japanese phrase meaning “to avoid errors” and includes preventing the probability of mistakes from happening. In this technique, employees find and eliminate human errors and inefficiencies in the manufacturing process.
The Kaizen technique is a robust strategy that offers a continuous engine for business enhancement. It is the process of constantly identifying, monitoring, and implementing enhancements. This is specifically useful practice for the manufacturing sector. Ongoing and Collective enhancements ensure a decrease in waste and
instant change whenever a tiny ineffectiveness has happened.
Value Stream Mapping is the technique that schedules the current flow of information and materials for designing the manufacturing project. The aim is to eliminate waste and ineffectiveness in the value stream and generate leaner operations. It finds seven different kinds of waste and three kinds of waste-eliminating operations.
The Cause and Effect Analysis diagram is also known as the fishbone diagram because it represents the fish's skeleton. It is one of the most popular six sigma tools since it enables us to research different reasons for a problem. The first phase is carrying out the analysis to find the problem we want to solve. We must write who works on the process and where and when the process happens.
The next step is to write the problem in the box on the left side of the paper. After that, draw the horizontal line till the end of the paper. From there, draw the vertical line dragging over the “spine.” Over these lines, we can write the main reasons behind the problem and think using any probable reasons. We can further break down these reasons into the sub-causes. After completing the diagram with all the probable reasons for the problem, we can analyze our results. The results may require more testing and analysis.
Pareto Chart is the evident symbol of the Pareto principles: 20% of input gives 80% of output in any given condition. The plan links the perpendicular strip graph and the line graph. The bar graph represents the measures of the different process elements, ordered from highest to lowest one. The line graph demonstrates the merged total of these measures.
The devices indicate what part of the process impacts the most. For building such charts, we first find out the elements of the method and how to govern them. After completing that, we can store this data in the Pareto chart. This will allow you to understand how big the impact on the output of each part has.
A time-based visualization is used for improving and monitoring the quality. Control charts are primary tools utilized in statistical process control. There are several control charts to utilize, but the moving and individual range control chart is one of the most straightforward, versatile, and flexible charts to utilize. As it is widely utilized during the process of stability identification, the tool is helpful for constant data flow and for learning non-normality. Thus, the IMR control chart is one of the most frequently used control charts in Six Sigma projects.
Histogram is utilized to measure the process’s performance by mapping the frequency of different outputs with the histogram. Same as the bar chart, the histogram offers the exact representation of the process variation, allowing us to analyze the process outputs against customer requirements and desired results. Your team can work on the process enhancements if the histogram gives an irregular data division.
Six Sigma utilizes Process Mapping, which can be specified as the flowcharting process to allow the documentation of a particular business process. Documentation involves different aspects of the business processes, like decision points and overall work performance needed for satisfying particular client requirements. These flowcharts are regularly used in making enhancement suggestions.
Scatter Chart represents a pair of numerical data, with one variable on each axis, to look for the relationship between them. The points will be on a line or curve if the variables are related. The better the relation, the tighter the points will be get closed to the line.
When to use Scatter Charts
A Check Sheet is a structured and prepared form used for gathering and analyzing the data. This is the generic data analysis and collection tool that can be useful for various purposes, and it is considered as one of the best quality tools.
