The 5 Key Principles of Lean Six Sigma

The 5 Key Principles of Lean Six Sigma

Lean Six Sigma is a powerful, proven approach to improve the efficiency and effectiveness of a business. According to the American Society of Quality(ASQ), Lean six sigma is a fact-based, data-driven philosophy of improvement that values defect prevention over defect detection. The two approaches, namely Six Sigma and Lean, have been combined to form a useful and effective tool to enhance business processes. The Six Sigma method focuses on variation-reduction in waste, whereas the lean method emphasizes on its reduction and elimination. 

The Lean Six Sigma method aids in

  • Improving the delivery time of a product or service delivery.

  • Decreasing the chance of defect.

  • Reducing the cycle time of a process.

  • Optimizing key enhancements.

  • Reducing inventory wastage.

In order to eliminate waste, industries use various tools of lean approach, which include Kaizen, JIT(Just in Time), Value Stream Mapping, Kanban, etc.

The Lean approach is a theory focused on eliminating waste and driving customer satisfaction. According to the method, there are eight types of waste: defects, overproduction, waiting, non-utilized talent, transportation, inventory, motion, and extra processing. 

To eliminate this waste and produce the best results, an organization must follow the below five fundamental principles:

  • Focus on the customer:

Customer satisfaction is the ultimate goal of any organization. By giving value to the needs of the customer, an organization can enhance the quality of its product or service. Eventually, everything revolves around the opinions of the customer. Before executing any minor or severe modifications in a product or a service, it is necessary to keep in mind the demands of the customer and the market and also establish and maintain quality standards demanded by them.

  • Figure out the root cause:

It is necessary to figure out the root cause for the accomplishment of the working process. In order to achieve this:

  1. Business leaders must have a definite knowledge of the purpose of collecting data, and the type of data that has to be collected.

  2. Establish a standardized data collection method.

  3. Guarantee specific communication.

  4. Ensure a precise system for measurement.

After the data is collected, the primary work is to determine whether the data collected can meet the goals, or any changes are to be made. If needed, the data must be adjusted to optimize the process by concentrating on the root cause with minute variations incrementally.

  • Eliminate root causes:

After identifying the root cause, the next step is to eliminate it. In order to do so, a business manager has to be bold and must take immediate action. Simplifying or destroying these root causes is the ideal way to make the process effective and waste-free.

  • Teamwork:

The business leaders and team members must have an explicit understanding of lean six sigma processes. The members of the team must be trained in six sigma methods, including measurement methods and improvement tools. Also, every member of the team must improve his or her communication skills so that they can communicate efficiently with the customers and coworkers.

  • Create a culture of adaptability and responsive:

Lean Six Sigma always binds to accept a positive transformation. That is why any modification in the process should be communicated clearly amongst everyone at the beginning and also motivate the team to take the difference professionally. 

Lean Six Sigma captivates the best of both Six Sigma and Lean methodologies of project management. To implement the Lean Six Sigma methodology in your organization, it is essential to understand and apply the Lean Six Sigma principles and also enhance process improvement.
