What is the first recommended activity in Life Cycle Cost (LLC) analysis?

The first recommended activity in Life Cycle Cost (LLC) analysis is to define the system. This step is crucial because accurately understanding the system's purpose, functions, and boundaries sets the foundation for all subsequent analysis activities. By clearly defining the system, engineers and decision-makers are able to ensure that all cost estimates and resource allocations are relevant and targeted. This comprehensive definition includes identifying the system requirements, key stakeholders, and intended operational environment, which are essential for assessing costs effectively throughout the system's life cycle.

Engaging in this initial thought process also helps to identify potential issues early on and allows for a more accurate estimation of costs across different lifecycle phases. Defining the system is therefore not only a prerequisite for effective LLC analysis but also a strategic approach to integrate various perspectives and objectives that will influence the cost throughout the system's operational life.
