The two methodologies we’ve mentioned until now dealt with business processes.Six Sigma, on the other hand, focuses on manufacturing processes. The main idea behind it is minimizing defect rates – for every million opportunities, you shouldn’t have more than 3.4 inefficiencies.While there are a lot of Six Sigma tools out there, DMAIC is one of the most popular ones. The methodology helps perfect your manufacturing processes & consists of 5 steps…
- Define – Outline what the issue with any given manufacturing process is. Decide on the improvement goal & which tools or resources you’re going to use
- Measure – Look at the process as-is and measure its performance. Once you know what the metrics are, you’ll have a better idea on how to improve them.
- Analysis – Find the root cause of the issue. Why is the process underperforming?
- Improvement – Once you’ve identified the problem, try finding potential solutions.
- Control – Implement the new process on a small scale and benchmark the new results to the old.
