What is the first step after making a derivative classification decision?

The first step after making a derivative classification decision is to document it appropriately. This process is essential because it ensures that there is a clear and traceable record of the classification decision, including the rationale behind it. Proper documentation provides a basis for accountability and allows for future reference, particularly if questions arise about the classification.

When documentation is done correctly, it includes details such as the source material relied upon, the specific classification markings applied, and the individual responsible for the classification. This practice not only helps uphold compliance with security policies but also facilitates any necessary audits or reviews by ensuring that there is sufficient evidence of the decision-making process.

Other options, while potentially relevant under different circumstances, do not represent the immediate requirement following a derivative classification decision. For instance, notifying a supervising authority or discussing the decision in a team meeting may be necessary at some point, but these actions typically come after documentation has been completed.
