👉 Function engineering is a design approach that focuses on creating and optimizing software systems by defining the functional requirements and then systematically developing, testing, and refining those functions to ensure they meet the desired outcomes. It involves breaking down complex systems into smaller, manageable components or modules, each responsible for a specific function, and then integrating these modules to form a cohesive whole. This method emphasizes modularity, reusability, and scalability, allowing developers to modify or replace individual functions without disrupting the entire system. By prioritizing clear, well-defined functionalities, function engineering enhances maintainability, facilitates collaboration among team members, and supports the iterative development process, ultimately leading to more robust and adaptable software solutions.
