Improvement Tools & Techniques

Design Of Experiment (DOE)

Introduction

Design of Experiment (DOE) is one of the most powerful improvement tools. DOE may be used in the design of all information-gathering exercises where variation is present. It is a strategic, enabling methodology to improve process yields and product quality. At the same time, it reduces the product development time and overall costs by changing one or more process characteristics after studying their effects on the product.

In recent years, quality practitioners have used DOE as a key driver for many quality improvement initiatives including Six Sigma. DOE has provided substantial savings to thousands of companies by solving difficult quality problems, reducing product and process variation, and optimizing product/process performance and consistency.

Benefits of Implementation

The organisation will be able to:

• study multiple product design and/or process variables at the same time and provide very reproducible results
• evaluate thousands of potential combinations of numerous variables at different settings or levels for the best overall combination in a very small number of experiments
• save on experimental and time costs
• increase the odds of identifying solutions to nagging quality problems
