The AI team take a deep dive into the case study on the successful system design process of the LuZ SEGS-1 solar power system’s control and electronics in 1981, using a modified Functions Requirements Answers and Test (FRAT) approach. The author, Joseph Kasser, uses the SEGS-1 project as a case study to illustrate how FRAT facilitates understanding the relationships between system functions, physical decomposition, and requirements. The paper presents several design choices and their rationales, highlighting the iterative and parallel nature of the FRAT process. Furthermore, it offers valuable lessons learned from the SEGS-1 project regarding systems engineering best practices, such as prioritizing simplicity and employing diverse perspectives. Finally, Kasser emphasizes the importance of considering human factors and managing complexity in systems engineering.
