The official business definition of Key Dependencies is a set of tasks, activities, or processes that must be completed in order for a business to achieve its desired outcomes. These tasks, activities, or processes are essential to the success of the business, and if any of them are not completed, the business may not be able to reach its goals. Key Dependencies can be broken down into three main categories: internal, external, and cross-functional. Internal dependencies are tasks or activities that must be completed within the business itself, such as creating a marketing plan or developing a new product. External dependencies are tasks or activities that must be completed outside of the business, such as obtaining customer feedback or obtaining regulatory approval. Cross-functional dependencies are tasks or activities that involve multiple departments or functions of the business, such as coordinating the efforts of the sales and marketing teams. Key Dependencies are important for businesses to identify and manage in order to ensure that all necessary tasks are completed in a timely and efficient manner.
