Outline is usually used to organize one's ideas and thoughts about a particular topic in order to facilitate an effective writing of an essay. There are four principles that work together to ensure a balanced outline structure, these are: parallelism, coordination, subordination and division. The principle of coordination states that information that are found at the same level should be of equal significance. For instance, information of equal value should be designated with the same alphabets or numbers. The principle of coordination allow writers to present a consistent write up.
