Assume a simple dilemma of hiring temporary workers or asking regular staff to work overtime. A decision analysis seeks to identify the best course of action. Using the yes / no type of analysis requires asking questions, and each “yes" or “no" leading to further questions.
For example, weighing the options, the first question is "will hiring seasonal workers reduce labor costs compared to providing overtime?"
If “yes," the next question is “are seasonal workers available?." If “no," the logical flow ends.
If “yes," the next question is “is hiring seasonal workers legit?". If “no," the logical flow ends.
If yes, the next question is “are seasonal workers competent to do the job?". Here, “yes" means hiring seasonal workers remains the best course of action, as no further deliberation is required or possible. If “no" the onus is on the decision maker to consider whether the benefits up to this stage perceives the perceived benefits of another alternative. A “no" answer might lead to another yes / no analysis, such as “Is training seasonal workers more cost-effective than providing overtime to existing workers." If “no," then the decision is abandoned, and the decision maker considers the option of overtime. If “yes" the next question arises “is on-the job training the best option." If “yes," the node ends here, and if “no," the next question arises, “Is simulated exercise the best training option," and so on.
