A written plan will help you communicate goals and tasks but until you get to the point where you have to manage other people, I'd say don't make planning a seperate thing. Instead keep a document with the details you think need more planning and maintain it as you go about the actual work. Refer back to this document whenever you need to as you interact with people and revise accordingly.
