Final answer:
The true statement regarding structured decisions is that with a more structured decision, there is a need for summarized data. Structured decision processes benefit from data that is condensed yet accurate enough to follow established criteria and constraints for selection.
Step-by-step explanation:
To address the question of which statement is true regarding structured decisions, it is necessary to understand the nature of structured and unstructured decision-making processes. Structured decision-making benefits from summarized data that is still accurate but compiled in a way that is manageable and relevant to the decisions needed. With a structured decision process, there's a framework in place that facilitates decision-making by providing criteria and constraints that guide the selection of the best option available. In contrast, less structured decisions, which may occur in more complex and uncertain situations, can require more flexible and detailed information to navigate through ambiguity. However, the assertion that less structured decisions need more well-defined and accurate data is not necessarily true, as these types of decisions often rely on heuristics due to the lack of structure and clear criteria. Therefore, statement b, "With a more structured decision, there is a need for summarized data," is the true statement among the options provided.
