Speed. Quality. Low Cost.
These universal goals have been around as long as there has been competition in business. Many separate disciplines have evolved to achieve these goals. People may poke fun at the various improvement programs that have come and gone over the last 20 years. But the facts are: companies have gotten much better, competition has gotten tougher, the marketplace is more global, customers are very demanding, and the game continues to increase in difficulty.
The Lean Six Sigma Concept can support improvements on Speed, Quality and Cost, because it blends Lean, with its primary focus on process speed and the elimination of waste, and Six Sigma with its primary focus on process quality.
Lean Six Sigma uses a Roadmap, the so-called DMAIC Cycle that provides a guideline how to improve products and processes or solve problems.
- Define:Define the project goals and customer (internal and external) deliverables.
- Measure: Measure the process to determine current performance; quantify the problem.
- Analyze: Analyze and determine the root cause(s) of the defects.
- Improve: Improve the process by eliminating defects and reduce variation.
- Control:Control future process performance.
Why does Lean need Six Sigma?
1. Lean does not explicitly prescribe the culture and infrastructure needed to achieve and sustain results.
2. Customer Critical-to-Quality (CTQ) needs are not front and center.
3. Lean does not recognize the impact of variation.
Why does Six Sigma need Lean?
1. Six Sigma does not explicitly prescribe the identification of waste (MUDA).
2. Improvement of process speed or cycle time is, at least in the publications, not in focus of Six Sigma.
3. Specific Lean Tools for Speed Acceleration (SMED, Total Productive Maintenance, 5S,…)
4. Methods for rapid action are partly missing in Six Sigma Projects.
5. Six Sigma Quality is approached much faster if Lean eliminates non-value-added steps.
We have many years of experience in implementing Lean in organizations to decrease waste (Muda) and increase efficiency in all processes. You need further information? Click here.
