Organizing is a nonacademic skill.
Management is a personal skill and attitude towards something tangible or intangible like time, money, work, knowledge, health and etc. that purports to and is driven by a specific goal or purpose. Unlike, writing, which is a learned behavior that has become an attained skill was taught exteriorly. Close reading is also one learned behavior and as well as research. Management can be a learned behavior but not directly from academics since organizing and managing isn't limited to such spectrum. It may have been lectured at home by your parents or guardians or a colleague, even someone in authority.
