The main concept used to establish organization maps is the business unit. In enterprise architecture, organization maps are visual representations that illustrate the structure and relationships within an organization. By focusing on the business units, which are distinct parts of a company aligned with specific lines of business, functions, or responsibilities, these maps facilitate understanding of how different segments of the organization operate and interact with one another.

Business units are fundamental for mapping out processes, resources, and strategic initiatives within an organization. They help identify the flow of information, decision-making hierarchies, and inter-departmental collaborations necessary for aligning the organization's goals and operations. This organizational structure is key to effectively designing and managing enterprise architecture, allowing for improved communication and efficiency in achieving business objectives.

In contrast, while the product lifecycle, financial department, and marketing strategy may contribute to the overall operational landscape of an organization, they do not serve as the primary framework for developing an organization's structure or mapping its relationships. The business unit approach provides a clearer and more holistic view that is essential for enterprise architecture.
