Corporate levels, also known as ECHELONS, refer to the hierarchical structure of a company. It is composed of different levels of management, each with its own set of responsibilities and authority. The highest level is typically the CEO or president, followed by the executive team, then the middle management, and finally the lower-level employees. Each level has its own set of duties and tasks that must be completed in order for the company to run smoothly. Corporate levels are important for ensuring that all employees are working together towards the same goals and objectives.
