Your experiences, expertise, and skills form a body of knowledge as you study any given topic. As you apply your skills in productive ways, you refine that knowledge. To actively enhance or improve your knowledge of a subject, you generally need to break the knowledge into manageable pieces. This becomes particularly important when you need to transfer this knowledge to other people or systems. The decomposition of knowledge and the ability to transfer it can actually be a great way to further refine your understanding of a topic.
