Decision analysis is a systematic approach used to evaluate and make choices among different options. It involves identifying the possible alternatives, assessing their potential outcomes, and considering the associated risks and benefits. This method helps individuals and organizations make informed decisions by quantifying uncertainties and clarifying preferences. The process often utilizes tools such as decision trees and cost-benefit analysis to visualize options and their consequences. By breaking down complex decisions into manageable parts, decision analysis aids in selecting the best course of action based on logical reasoning and available data.
