To overcome the gap between academic research and managerial practice in the management field, we propose a normative research method for management sciences on the basis of nomology theory and PriorityPointing Procedure(PPP). It suggests that the solving of a complex management problem should be broken down into  four general activities, and  eight principal activities  within a system. The wheel of this normative research method for management sciences can be used to find an equilibrium between doing too much or too little of each activity, a balance between thought and action. In the analysis of the theoretical meaning of this PPP-based normative research method for management sciences, the reason why it helps to integrate management theory with practice and thereby to overcome the gap between academic research and managerial practice is presented. Further, the applications of PPP method to managerial practice are addressed. Applications of the PPP in Ireland show that it  helps to avoid the dilemmas of pure positivistic and pure interpretative approaches to research, and helps to bridge academic research and managerial practice in the field of management sciences.
