Introduction to design of experiments
- Have you ever wondered how a little sleep will get away with the night before a test in order to study more? Or have you ever worried if the temperature of the testing room will impact your performance? And just what is the best combination of sleep hours, study time and room temperature. In a six Sigma project, after the root causes or key access have been proven earlier, now the main question in the improve phase is, what is the best combination of settings for the proven Xs to optimize the output Y? Let's go back to our example. If the Xs, the impact test scores are hours of sleep, study time and room temperature then what is the best combination of these factors to improve test scores? The tool that is best suited for doing this is called design of experiments or DOE. To start, here's some basic DOE terminology. In this example, sleep duration, study time and room temperature are called the factors or independent…
