Sequential experimentation is very efficient way of doing experiments for scientific discovery and process and product design. In this presentation, some sequential experimentation approaches and their uses are presented, based on the experimental data from factorial design. From the results of the initial factorial design, five follow-up approaches are suggested; steepest ascent (SA), central composite design (CCD), asymmetric composite design (ACD), overlapping non-central composite design (ONCD), and non-overlapping non-central composite designs (NNCD). Analysis methods for ACD, ONCD, and NNCD are presented using the initial factorial and follow-up design data. Comparison on the number of design points and design efficiencies are given for CCD, ACD, ONCD, and NNCD. A flow chart of employing the sequential design approaches is given to help the practitioners. The performances of these sequential approaches are evaluated based on a simulation study from a response surface test bed.
