Explanation
According to the BABOK Guide, defining the business needs is the process of identifying the ends that the organization is seeking to achieve. Business goals and objectives are statements of the desired outcomes of the change initiative that align with the organization's strategy and vision. They provide the context for identifying and evaluating alternative solutions that can satisfy the business needs. Alternative identification, solution assessment, and requirements are parts of other processes that follow defining the business needs.
