Lean Six Sigma Black Belt

A Certified Lean Six Sigma Black Belt is someone who has completed the six-sigma certification process. The CLSB designation recognizes individuals who have mastered all six domains of knowledge that comprise what it means to be a Black Belt. This certification shows your commitment to the Lean Six Sigma methodology and process improvement. It's designed for those who want to be more than just knowledgeable about Lean Six Sigma, but also demonstrate their skills as an expert in it.
Lean Six Sigma is a set of business practices that can be used to improve efficiency and reduce errors. It was developed by Motorola in the 1980s and has since been adopted by many other companies around the world. Six Sigma focuses on eliminating defects and reducing variability within processes. The goal of Six Sigma is to provide customers with products or services that are 99.99% defect-free, meaning they produce an error rate (defect) of 3.4 parts per million or less.

The 5 Key Principles of Six Sigma

Principles of Six Sigma

  • Focus on Customer: No matter what industry or domain you are in, every business survives on the customers and their needs. The primary goal is to keep the customers satisfied and create products as per their requirements.
  • Map out a Value Stream: It is important to map the steps required to be taken before you improve the process. One way to do this is to take the help of flowchart that uses symbols to show the steps involved in any process. They are used for processes that have many steps, or where it can be difficult to understand what each step should be.
  • Get Rid of Junk: If any problem is identified, make changes and remove the defects. If the value stream fails to detect, use tools that will help to detect outliers and problem areas. Lean Six Sigma encourages practices that streamline the functions to prevent junks. Some of the standard practices to reduce waste are using templates and checklists, documenting the processes, and automating the easy stuff.
  • Create a Flexible Ecosystem: The fundamental essence of Six Sigma change and business transformation. When a defect or faulty process is removed, work practice will change. A robust culture of flexibility can endure changes in procedures, eventually leading to successful project implementation. People involved in the project will be trained for a quick and seamless adoption.
  • Communication: Despite having a flexible ecosystem, if you cannot communicate the new processes effectively, your entire project may go for a toss. With proper communication, you can train your employees on the new processes and encourage taking their feedback to develop mutual understanding. Here are some ways for effective communication:
  1. Create process maps that will help you explain and make them easy to understand.
  2. Create a knowledge base and make it easily accessible for employees and stakeholders.
  3. Update the knowledge base to make it accessible for everyone.

The Six Sigma Methodology

DMDAV and DMAIC are the two main sigma methodologies.

The DMAIC methodology is a tool many organizations use to drive continuous improvement. It can be applied in any situation where you need to identify what needs to change, measure the results of that change, and then improve your process until it meets your desired outcome.

  • Define: What are the problems that your company is facing?
  • Measure: How do you know if you're making progress towards fixing them? Collect data that serves as a foundation for improvement.
  • Analyze: What are the possible causes of these issues, and what should be done about them?
  • Improve: Develop a plan for implementing corrective actions.
  • Control: Implement your changes to see their effects on the problem.

DMADV is a framework for designing and analyzing the performance of any system. It is used when the existing processes do not meet customer expectations. The five phases are: D – Define, M – Measure, A – Analyze, D – Design, V – Validate

  • Define: Define the process and objectives.
  • Measure: Measure the characteristics and qualities of a product or service.
  • Analyze: Analyze the data to find the best process.
  • Design: Design and test the process or product/service.
  • Verify: Ensure the designed product, circle meets the requirements and performs as per the expectations.
