Which of the following is NOT a method of incorporating classified source material into new material?

Planning is the process of organizing and outlining how to approach a task or project, including considerations about the security and classification of information. However, it does not involve the direct incorporation of classified source material into new material. In contrast, the other options—analysis, summarization, and synthesis—are all methods that specifically engage with classified sources to create new documents or products.

Analysis involves reviewing and interpreting classified information to understand its implications or relevance. Summarization entails distilling the essential points from classified material to generate concise, clear content that still maintains the integrity of the source's classification. Synthesis goes a step further by combining information from multiple classified sources to develop new insights or conclusions, integrating various perspectives into one coherent document. Each of these methods directly deals with how classified source material is transformed into new informational products, reinforcing their distinct roles in derivative classification processes.
