Background SAS-065 has developed a C2 Maturity Model for NATO Network Enabled Capability SAS-065 is engaged in a variety of activities to “validate” this model Case studies: Analysis of historical complex endeavors to establish construct validity Analysis of Experimentation Data to test a set of maturity model hypotheses ELICIT is an experimentation platform that instruments the actions of a group of participants engaged in a situational awareness problem ELICIT experiments have explored differences between “edge” and “hierarchical” organizations
4
ELICIT Scenario The goal of each set of participants is to build situational awareness and identify the who, what, when, and where of a pending attack Participants can share factoids directly with each other or post factoids to websites Participants build awareness by gathering and analyzing factoids and interacting with one another No one is given sufficient information to solve their assigned problem without receiving information from others The receiving, sharing, and posting of factoids and the nature of the interactions between and among participants can be constrained C2 approach for this series of experiments were designated prior to the start of the run as Hierarchy or Edge Hierarchy Edge
5
Hypotheses “Hierarchical” organizations as instantiated in ELICIT experiments correspond to De-Conflicted C2 in the NATO C2 Maturity Model “Edge” organizations as instantiated in ELICIT experiments correspond to a higher level of maturity in the NATO C2 Maturity Model Hypotheses: Edge organizations exhibit the behaviors associated with Coordinated and Collaborative levels of C2 Maturity Hierarchical organizations exhibit the behaviors associated with the De-conflicted level of C2 Maturity Edge organizations exhibit higher levels of effectiveness and efficiency than Hierarchical organizations

Dependent Variables MOE = Quality of Awareness and Shared Awareness
Correctness (Authorized Correct IDs) Timeliness (Person-Minutes with Correct IDs) Accuracy rate (Correct IDs/Total IDs) Efficiency, Given Effectiveness Productivity (Correct IDs/Total Actions; Correct IDs/Person-Minutes Available) Speed (Time of Earliest Correct ID) Agility Effectiveness over problem difficulty
10
C2 Approach Independent Variables
Hierarchy v. Edge We expect Hierarchy to map to De-conflicted and Edge to map to a more mature level Each run will be mapped to a point in the C2 Approach Space based on observed behaviors Rules of Interaction Website access Sharing permissions Initial Distribution of Factoids Invariant in existing runs
11
C2 Approach Intervening Variables
Patterns of Interaction Characteristic path length Clustering coefficient Connectedness Distribution of Information The average number of unique facts to which each participant has access as a function of time
12
Measures of C2 Effectiveness (MOCE)
Quality of Information Position Percentage of relevant facts for the assigned task that a participant can access as a function of time Percentage of key facts for the assigned task that a participant can access as a function of time Extent of Shared Information The average number of participants that have access to each fact as a function of time The average number of participants that have access to each key fact as a function of time
13
Intervening Behavioral Variables

14
Other Independent Variables

Other) Communications media Postcards Chat Time available Degree of Education (Graduate, Undergraduate) Seniority (Rank) Subcultures (Military, Civilian, Special Forces, Civil Servants)

MOE: Correctness Fraction of Participants with Correct IDs
Edge Hierarchy Note: a more detailed search of the 94% correct value in the Edge runs showed that 16 correct guesses occurred in the run Edge_with_Chat_1A.log which uses a chat capability. The other high percentages occur in Edge_with_Chat_5A.log, which uses chat, and some of the NPS runs which may have used postcards.

21
Measuring Timeliness: Person-Minutes with Correct ID
In the ELICIT scenario, operational value is associated both with the number of participants achieving the correct answer, as well as when they achieved it Person minutes with correct ID captures the proportion of possible situational understanding achieved by trial participants over the time of the trial For each minute, each participant’s level of understanding is assessed by the score assigned to his/her most recent identification attempt This value is summed over the duration of the trial to arrive at the person-minutes correct for each participant Person-minutes correct for the trial is calculated by summing over all participants A ratio of the person minutes correct for the trial to the total person minutes available in the trial adjusts for varying trial lengths
