So where does Design of Experiments fit into Six Sigma?Six Sigma is ready knowledge and controlling case study solution model of key method variables called inputs or xs in order to obtain stronger outcomes on task outputs or ys. In Design of Experiment terms these inputs or xs are often called factors and case study answer outputs are called responses. Wait a minute, isnt this what Design of Experiments is all about?Of course, for just about 100 years Design of Experiments has been proven to be one of case study answer best known strategies for validating and discovering relationships between responses and factors. In Six Sigma terms it is discovering case study solution courting among outputs called ys and inputs called xs. Todays Six Sigma Belts are primarily taught to focus their use of Design of Experiments in case study answer Improve phase of DMAIC and case study solution Optimize phase of IDOV. For DMAIC Six Sigma training case study answer most typical experimental designs taught are factorial and fractional factorial designs. 8, 15. 2, and 16. 3%, respectively.
