Learn Top 10 Powerful Tools For Six Sigma

Lean Six Sigma tools play a vital role in business processes and are designed to reduce manufacturing faults. Over the past years, Six Sigma tools have identified defects and gaps in business operations, enabling the firm to fill those gaps and increase its overall performance.

The article will walk you through the Six Sigma tools list and how these methods can optimize and improve your business processes.

What is Six Sigma?

Six Sigma is a set of management tools and techniques concerning process performance and variability that help organizations achieve higher success. Six Sigma is a data-driven approach that uses a statistical methodology to reduce defects and increase profits. An organization can use Six Sigma tools to improve its management effectiveness. A reduction in defect rates is reasonably likely for workforce quality, employee morale, and product or service quality. 

Lean Six Sigma is a data-driven improvement methodology prioritizes defect prevention over defect detection. It improves customer satisfaction and financial results by reducing variation, waste, and cycle time. It supports job standardization and flow and creates a competitive advantage. Every employee should collaborate on efforts where waste and variety exist. Lean Six Sigma tools and techniques help your business to improve its efficiency. Specific lean six sigma process improvement tools and techniques can identify flaws and are time efficient and profit-driven.

Six Sigma Tools

DMAIC

  • D- Define
  • M- Measure
  • A- Analyze
  • I- Improve
  • C- Control

Six Sigma DMAIC tools help develop a high-quality product or service by creating an efficient process through thorough data analysis.

  • Define the problem, improve activity, improvement opportunity, and project goals.
  • It’s one of the best Six Sigma tools to measure process performance and improvement
  • Six Sigma quality tools analyze the process to determine the root causes of variations and poor performance defects.
  • Problem-solving tools Six Sigma improves process performance by addressing and eliminating the root cause.
  • Six Sigma quality management tools control the improved process and future process performance.

The 5 Whys

To determine the root cause of the problems in your organization, we use one of the Six Sigma tools called “The 5 Whys”. This tool is used as a part of the Analyze Phase in DMAIC.

How to Use 5 Whys?

  • Writing down the problem so that the whole team can focus on it individually
  • Ask why there was a problem
  • If your answer does not sum up the situation, then ask again why the problem is occurring.
  • Repeat these questions five times so that you reach a solution
  • Five times is not a fixed number, you may ask more than five times, and you will have clarity by then.

Value-Stream Mapping

Value-Stream Mapping is one of the quality management tools in Six Sigma that represents the knowledge and materials used to produce the assets for clients. The tool helps to streamline the process.

The Value-Stream Mapping Six Sigma tool helps to identify three main things;

  • Value Enabling Activities: Identifying the activities which add value to your processes.
  • Value-Adding Activities: Identifying the activities that can add value to the process
  • Non-Value Adding Activities: Identifying and eliminating the activities that do not add value to your operations.

Regression Analysis

A Regression Analysis is one of the best Six Sigma tools that estimates and visualizes the connection between variables, with an input variable serving as the independent variable and an output variable as the dependent variable. You can use this function to spot patterns or anomalies in your workflow by recording the input and output variables.

Regression analysis, in simple terms, is a statistical method used to determine the degree to which two variables are related. If the relationship is sufficiently strong, one may accurately determine the value of one variable based on the importance of another variable using a simple linear formula. However, one should be cautious when performing regression analysis.

Pareto Chart

A Pareto Chart is the most critical tool of Six Sigma because it helps teams identify the resources that account for 80% of problems in the process. A Pareto Chart is known as Six Sigma quality tools for graphical representation that reveals which part of the procedure has the most significant effect on output. To construct one of these charts, you must first determine the process steps and how to measure them. Six Sigma teams can see the process’s greatest issues when data from different groups is presented. This will allow you to recognize which aspect must be dealt with immediately.

FMEA

An FMEA (Failure Modes and Effects Analysis) is one of the Six Sigma program tools and methodologies for identifying and eliminating manufacturing weaknesses by examining the consequences of components, assemblies, and subassemblies. FMEA, developed in the 1950s, is a procedure used to discover and correct faults before they occur. As a result, quality improves across their processes, services, and products.

Kaizen

Lean Six Sigma tools achieve improvement through the Kaizen method, which consists of monitoring, identifying, and implementing minor improvements in manufacturing processes by involving all employees and managers and encouraging them in the process. It also ensures manufacturing inefficiencies are eliminated daily through the collective abilities and knowledge of everyone working for the company. Furthermore, waste reduction is also ensured.

Kanban System

A Kanban System is a problem-solving tool, Six Sigma, which is used in a supply chain control system that uses a just-in-time inventory control system to reduce costs. Kanban is a Japanese word that means ‘billboard’. This system improves efficiency and focuses on the business by activating the supply chain only when the demand requires it, allowing additional resources to be utilized more effectively.

Poka-Yoke

Human error can be prevented by identifying and rectifying mistakes throughout the production and manufacturing processes, using a technique called Poka-yoke. The purpose of the process is to highlight an error in the process. It prevents a process from proceeding to the next step until proper conditions are met.

Tallyfy

Tallyfy lets businesses create material and information flows to automate user and client interactions. It allows them to develop cause-and-effect diagrams and detailed analyses of any problem and possible solutions for roles across the value chain. Every production step is broken down into a process map and summarizes the data. It also generates cause-and-effect diagrams.

Conclusion

Six Sigma Tools are highly effective in identifying errors and highlighting mistakes which are usually neglected in a business process. Using these tools will make the process smooth, time efficient and will increase efficiency.
