Question

7. Discuss the Six Sigma Methodology for the creation of an entirely new tool to solve an identified problem.

Answer 1

Six sigma is a method which incorporates certain techniques to improve the performance of business or operational processes. Six Sigma focuses on defect elimination and keeping the number of defects to a minimum. It helps in reduction in process variation by focusing in the data-driven approach. The key methodologies in six sigma is 1)DMAIC and 2)DMADV

DMAIC Methodology

1) Define- Define the problem or the issue that needs to be addressed.

2)Measure- Measure the problem as much as possible. Data should be collected from processes and established metrics.

3)Analyse- The collected data must be analysed using data analytics technique.

4)Improve - Improve the processes, methods, by using improvement techniques, cause-effect analysis, brainstorming, Quality improvement projects etc.

5)Control- Control the implemented improved processes by monitoring the process and reducing process variations.

DMADV Process- DMADV is used for introducing new processes and is not used for existing processes.

1)Define: Define the requirements of customer.

2)Measure- Measure the customer needs or requirements. The requirements should be converted into engineering or statistical terms.

3)Analyze- Analyze the process that will be required to translate the customer needs into physical processes.

4)Design- Design the processes which will meet the customer requirements.

5)Verify- Verify the designed processes and the design performance of the end product if it meets the customer requirement or not.
