A Functional Unit is a specific component or entity within a system that performs a distinct function or set of functions, often used to measure and compare the efficiency and performance of processes. It is crucial in systems analysis and life cycle assessment to ensure consistent and meaningful comparisons between different systems or products.

A distinct function is like a special rule that tells us how to change one thing into another, but it makes sure that every starting thing gets its own unique ending thing. This means no two different starting things can end up being the same after the rule is applied.

Systems Analysis is a process of studying and understanding complex systems to identify problems and propose solutions, ensuring that the system's components work together effectively to meet organizational goals. It involves examining the system's requirements, functionalities, and interactions to optimize performance and enhance decision-making processes.

Life cycle assessment (LCA) is a systematic method for evaluating the environmental impacts associated with all stages of a product's life, from raw material extraction through to disposal. It provides a comprehensive framework to identify opportunities for environmental improvement and supports decision-making for sustainable development.
