These articles review practical aspects of experimental design relevant to intervention science, and also attempt to correct some pervasively held misconceptions.  Charkraborty et al. and Nair et al. are aimed at biostatisticians and health scientists, whereas Collins et al. and Dziak et al. are aimed at behavioral scientists.  These articles provide a rationale for considering a factorial experiment and may be useful citations.
