Functional integration refers to the process of combining different functions or systems to work together seamlessly. This approach is often used in various fields, such as business, software development, and engineering, to enhance efficiency and improve overall performance. By integrating functions, organizations can streamline operations, reduce redundancy, and foster better communication among teams. In the context of software, functional integration allows different applications or modules to share data and processes. This can lead to more cohesive user experiences and simplified workflows. For example, integrating a customer relationship management (CRM) system with an email marketing platform can help businesses manage customer interactions more effectively and automate marketing efforts.
