CHAPTER OVERVIEW AND LEARNING OBJECTIVES

Most experiments for process design and improvement involve several variables. Factorial experimental designs, and their variations, are used in such situations. This chapter gives an introduction to factorial designs, emphasizing their applications for process and quality improvement. Designed experiments are widely used in the DMAIC process, ...
