Stepwise method provides a data driven approach to selection of your predictor variables. In general the decision to use data-driven or direct entry or hierarchical approaches is related to whether you want to test theory (i.e., direct entry or hierarchical) or you want to simply optimise prediction (i.e., stepwise and related methods).
