Six Sigma

Six Sigma is a highly structured and data-driven methodology used in the manufacturing industry to improve quality and efficiency. Six Sigma offers a powerful toolset to help organizations achieve operational excellence and continuous improvement.

The primary goal of Six Sigma is to eliminate defects and minimize variability in processes, leading to improved customer satisfaction, reduced costs, and increased profitability. This is achieved through a combination of data analysis, statistical methods, and team-based problem-solving.

One of the key elements of Six Sigma is the DMAIC process, which stands for Define, Measure, Analyze, Improve, and Control. This process provides a systematic approach to solving problems and improving processes, starting with a clear definition of the problem, followed by the collection and analysis of data, and ending with the implementation of sustainable solutions.

Another key aspect of Six Sigma is the use of statistical tools and techniques to measure and improve process performance. This includes process mapping, hypothesis testing, design of experiments, and control charts, among others. Six Sigma also relies on a highly-skilled workforce, with individuals trained in statistical analysis and problem-solving techniques.

One of the key benefits of Six Sigma is its ability to drive continuous improvement. This is achieved through regular monitoring and measurement of processes, coupled with ongoing analysis and improvement efforts. Six Sigma provides organizations with a roadmap for sustained, data-driven improvement, helping to ensure that performance gains are maintained over the long-term.

In a nutshell, Six Sigma is a powerful tool in the arsenal of any Lean Management Expert. It provides organizations with a systematic approach to improving quality and efficiency, while also driving continuous improvement and driving long-term success. Whether you are looking to optimize a specific process, or seeking to drive broader organizational change, Six Sigma provides the methodology and tools to help you achieve your goals.

DMAIC

Define, Measure, Analyze, Improve, Control. Incremental process improvement using Six Sigma methodology.

DMAIC can bee seen as a data-driven improvement strategy and for sure is part, or will be a part, of your organizations SIX SIGMA quality initiative. DMAIC is an acronym for: Define, Measure, Analyze, Improve, and Control.

DMAIC is a cyclical process such as the PDCA is. The reason to go for the DMAIC is to strive for the best result possible with a structured approach.

These process steps are:

DEFINE: the customers and their CTQ (Critical to Quality) and the core process involved.

• Who are your customers?

  • What are their requirements for products or services?

  • What are their expectations?

• Go for a value stream and map the process flow through the complete business process

MEASURE:

• Define a plan on how to collect data from your core process

• Go for different sources of data in order to be as specific as possible on defects and metrics

ANALYZE:

• While analyzing the data along the process map make sure to identify the real root cause of defects and

• point out opportunities for improvement

• Compare shortfalls with the results of customer surveys

• Determine gaps between targeted performance and current performance

• Prioritize potential improvement measures

• Identify variation and their source

IMPROVE:

• Gemba Walks

• Improvement Kata

• Kaizen Workshops

• Target is to improve the current process in a simple and effective way

• Develop a prioritized action plan

• Do it!

If you want a structured approach, just read our PDCA article.

CONTROL:

• Stay tuned on your process improvement measures

• Make sure that they stay on track

• Prevent falling back to the “old way”

In the end, when you are in charge, require the full documentation. Make sure that everything implemented is well documented and a clear monitoring is installed that deviation can be fast identified.

Having or installing a sustainable problem solving culture in your organization will be key for the future. Make sure to institutionalize problem solving or a kaizen culture through training, training and more training.
