I am doing a bachelor's degree in international relation besides this I am a good writer. Obviously, the level of authority affects the extent of responsibility to determining strategy, decision-making, managing other people, and for executive roles, deciding direction, policy, and delivering corporate performance.
Wherever possible refer the detail of standards and process to your 'operational manual' or 'agreed procedures' or 'agreed standards' rather than allowing the job description to become a sort of operating manual. If my boss or employer is asking for you to detail your tasks at length in a job description, encourage him/her/the organization to put this level of detail into an operational manual - it will save a lot of time.
I will be creat a good opportunity to frame the role as you'd like it as well as reflect how it is at the moment, so try to think outside of the normal way of thinking, and if this is difficult seek the input of somebody who is less close to things.
