A decision chart is a type of diagram used to make decisions and evaluate multiple options. It shows the key steps in the decision-making process, beginning with a central decision point (Key A). From here, it shows all possible outcomes or paths that one can take (Key B). As one moves down the chart, it will list additional decision points (Key C and D) and their respective outcomes or possibilities (Key E). The decision chart can be used to analyze any situation or problem requiring a choice to be made.
