The antonyms of "maps out" would be "abandons," "neglects," "ignores," "neglects," or "disregards." When a person fails to map out something, they are not planning ahead, and they are not taking the necessary steps to achieve their goals. Instead, they are leaving things to chance and hoping for the best. While this may work in the short term, it is not an effective long-term strategy. As such, individuals and organizations should take the time to adequately map out their plans and create actionable steps to achieving their goals. This will help them stay on track, be efficient in their work, and ultimately be successful.
