Traditional, deterministic LCGA results can generate endless debate over which alternative really has the lowest life-cycle cost.
Risk analysis is a technique that exposes areas of uncertainty that are typically hidden in the traditional deterministic approach to LCGA, and it allows the decision-maker to weigh the probability of any particular outcome.
By including all possible inputs into the analysis and weighing the probability of occurrence of each, risk analysis elevates the debate from the validity of LCGA results to deciding best public policy.
