I assume the PE stands for Professional Engineer? PMP and PE are totally different. PE is a profesional title that is intended for technical work while PMP is for managing projects. For engineers, the progression is from design engineer to project engineer and eventually over time (not necessarily by choice) becoming a project manager. Project managers do not perform technically work and essentialy an adminstrator responsible for project delivery & sometimes for purusing project opportunities. The roles of project engineer and project manager overlap as both pay attention to man power, budget and project delivery. I won't say one is better than the other. Often ther are 2 tracks in engineering career, the technical track and the management track. Which track to take or follow is the choice of the individual. A small percentage of engineers have both title or designations.
