ORA ALL-MEASURES REPORT ON THE UNION OF ALL SOCIAL NETWORKS IN THE CCK08 MOODLE FORUMS

I can't really interpret all of these values because I haven't gotten around reading the ORA manuals yet. Also, the reader should take note that ORA is a "risk assessment tool for locating individuals or groups that are potential risks given social, knowledge and task network information. (CASOS, http://www.casos.cs.cmu.edu/projects/ora/)"

COMMUNICATION RISK

---

The risk based on the level of communication and the authority structure of the organization. Are agents able to effectively communicate to accurately complete tasks? Is communication too centralized or decentralized? Do agents have recourse to managers to settle disputes?

CRITICAL EMPLOYEE RISK

---

The risk based on employees having exclusive knowledge, resources access, or task assignments. Would the removal of one or two employees from the organization greatly affect its ability to complete tasks? Do employees tend to have exclusive access to knowledge or resources?

PERFORMANCE RISK

---

The risk based on ability to complete tasks accurately. Is the organization able to complete all tasks? How well does the organization build consensus? How many tasks would be left undone if a single employee were selected for removal?

PERSONNEL INTERACTION RISK

---

The risk based on agent communication, either agents communicating who should not be, or vice-versa. Are agents with similar skills interacting? Are agents with complementary skills interacting? Are there groups of agents communicating in unexpected ways?

AA:Agent x Agent			128	v98

REDUNDANCY RISK

---

The risk based on redundancy in task assignments, resource access, and knowledge access. An organization with little redundancy is more adversely affected by an agent or resource no longer being available. On the other hand, too much redundancy makes an organization inefficient.

AA:Agent x Agent			293.096	v67

RESOURCE ALLOCATION RISK

---

The risk based on resource allocation on the organization's ability to complete tasks. Is agent workload evenly distributed? Do agents have access to the resources they need to complete tasks? Do agents have access to resources they do not use?

TASK RISK

---

The risk based on task precedence and task assignment. Do agents have the resources to complete their tasks? Are tasks highly interdependent so that the inability to perform one task prevents many other tasks from being done?

Node-level Tables

---

For each node class a file is made with tables for the measures. If there are no node-level measures of a particular type, then no file is generated.
