Six Sigma :: Software Testing
What is Six Sigma? Six Sigma is a statistical measure of variation in a process. We say a process has achieved Six Sigma if the quality is 3.4 DPMO (Defect per Million Opportunities). It's a problem-solving methodology that can be applied to a process to eliminate the root cause of defects and costs associated with it. Can you explain the different methodology for the execution and the design process stages in Six Sigma? The main focus of Six Sigma is to reduce defects and variations in the processes. DMAIC and DMADV are the models used in most Six Sigma initiatives. DMADV is the model for designing processes while DMAIC is used for improving the process. The DMADV model includes the following five steps: Define: Determine the project goals and the requirements of customers (external and internal). Measure: Assess customer needs and specifications. Analyze: Examine process options to meet customer requirements. Design: Develop the proces...
