Collection Management Framework (CMF):

Collection management framework (CMF) is a systematic process for identifying data sources and determining what information can be gathered from those sources to satisfy the Intelligence Requirements (IRs). The collection management framework validates whether the data source is feasible for collection by evaluating the relevance, reliability, accuracy, and completeness of the data; as it relates to accumulating data and producing threat intelligence from it.

The core questions driving a collection management framework are:
• What data is obtained and from where?
• What is available in the data?
• How long is the data stored?
• What types of questions can the data answer?
