A more thorough explanation:

Definition: Predecisional is an adjective that describes something that happens or exists before a decision is made.

Examples:

• A predecisional meeting was held to discuss the pros and cons of the new policy.
• The predecisional phase of the project involved gathering data and analyzing it.

These examples illustrate how the term predecisional is used to describe activities or events that occur before a decision is made. In the first example, a meeting was held to discuss the policy before a final decision was made. In the second example, data was collected and analyzed before a decision was made about the project.
