Functional Design Theory

Functional Design Theory focuses on creating systems or products by defining their essential functions—what they need to do—before addressing how to build them. It emphasizes understanding the purpose and requirements of each part to ensure that the overall design effectively accomplishes its goals. This approach helps optimize performance, reliability, and user satisfaction by aligning design choices with the specific functions the system must perform, rather than just focusing on how it looks or feels. In essence, it's about designing with clarity of purpose and functionality at the forefront.
