The American Society of Engineering Management describes the discipline of engineering management as:
Engineering Management is the art and science of planning, organizing, allocating resources, and directing and controlling activities which have a technological component.
Engineering Management is rapidly becoming recognized as a professional discipline. Engineering managers are distinguished from other managers by the fact that they possess both an ability to apply engineering principles and a skill in organizing and directing technical projects and people in technical jobs.
Of course, this description throws another wrench in the roles within a technology company. Where is the line between technical product management, technical project management and engineering management?
