Lists emphasize words, phrases, or groups of items. They can also help summarize or review steps in a sequence; items, materials, or supplies; points of interest or importance; criteria for evaluation; and conclusions or recommendations. Before creating a list, determine whether the information in it must follow a specific sequence (such as steps in a process) or if the sequence is unimportant (such as a list of materials). Determining whether or not a specific sequence is required will help you to determine is an ordered or unordered list is required.
