  COMPARE SOURCE LIST WITH REQUIREMENTS
  12-48. As target folders are compiled, a list of high-value sources will
  emerge. It is a simple matter to compare the source list with the PIRs and/or
  SIRs. This will lead to efficient and time-saving missions for the collectors.
  Rather than spend time meeting with sources who may have information
  concerning certain subjects, the HCT is able to tackle the collection process
  with foresight. Upon receipt of the mission, the OMT conducts mission
  analysis to determine the optimal way to meet mission requirements. Proper
  mission analysis enables the collector to properly focus his assets (sources) to
  gain the maximum amount of intelligence from those sources most likely to
  possess the highest quality information.
  12-49. The following products, which will focus the HCT’s collection efforts,
  can be prepared in conjunction with the ACE and joint intelligence centers:
  • Time event charts.
  • Source coverage overlays or matrices (see Figure 12-7).
  • Link analysis diagrams.
  • HUMINT portions of OPORDs and situation reports.
  12-50. The source coverage overlay or matrix helps tie in the source coverage
  to the requirements. It also helps identify gaps in collection. A collection
  matrix serves the same purpose. It supplies a quick reference when
  answering intelligence requirements. The matrices must cover both the
  geographical area and the placement and access of the source. A demographic
  overlay helps to identify ethnic groups in an area and to track events and
  patterns based on religious or ethnic differences. The overlay and matrix are
  examples of how source coverage can be tied to intelligence requirements.
  12-51. Source profiles are vital to screening sources for HUMINT collection
  operations and to identifying personnel that might be of interest to other
  agencies such as CI and TECHINT. As the situation changes, the HCT might
  be tasked with new collection requirements that cannot be answered by the
  current sources. The HCT is constantly looking for new and better sources.
  When presented with new requirements, the OMT develops a source profile
  of the type of individual that would most likely be able to provide the
  information required. This profiling can include placement, access, age,
  ethnic type, gender, location, occupation, and military specialty. The OMT
  first searches through existing local databases to try to get a source match. If
  not, it passes the profile to the HCTs along with the requirements to
  facilitate their screening of potential sources.
