What is the difference between internal and external development?

Internal development refers to the processes and activities undertaken within an organization to enhance its capabilities, products, or services, often involving existing employees and resources. In contrast, external development involves collaborating with outside partners, such as vendors, consultants, or other organizations, to achieve growth or innovation. While internal development focuses on leveraging internal knowledge and resources, external development seeks to incorporate external expertise and perspectives. Both approaches can be valuable, depending on the organization's goals and needs.
