  Association Matrix
  7-57. The association matrix is used to establish the existence of an association between individuals.
  Analysts can use association matrices to identify those personalities and associations needing a more
  in-depth analysis in order to determine the degree of relationship, contacts, or knowledge between the
  individuals. The structure of a threat organization is formed as connections between personalities are made
  (Figure 7-3).

  Relationship Matrix
  7-58. Relationship matrices are intended to show the nature of relationships between elements of the
  AO. The elements can include members from the noncombatant population, the friendly force,
  international organizations and adversarial groups. Utility infrastructures, significant buildings, media and
  activities might also be included. The nature of the relationship between two or more components includes
  measures of contention, collusion or dependency. The purpose of this tool is to demonstrate graphically
  how each component of AO interacts with others and whether these interactions promote or degrade the
  likelihood of mission success. The relationships represented in the matrix can assist the analysts in
  deciphering how best to use the relationship to shape the environment (Figure 7-4).
