Network Analysis
ORA is a network analysis tool that detects risks or vulnerabilities of
an organizationâs design structure. The design structure of an organization
is the relationship among its personnel, knowledge, resources, and tasks
entities. These entities and relationships are represented by the Meta-Matrix.
Measures that take as input a Meta-Matrix are used to analyze the structural
properties of an organization for potential risk. ORA contains over 100
measures which are categorized by which type of risk they detect. Measures
are also organized by input requirements and by output. ORA generates formatted
reports viewable on screen or in log files, and reads and writes networks in
multiple data formats to be interoperable with existing network analysis
packages. In addition, it has tools for graphically visualizing Meta-Matrix
data and for optimizing a networkâs design structure. ORA uses a Java
interface for ease of use, and a C++ computational backend. The current
version ORA1.2 software is available on the CASOS website: http://www.casos.ece.cmu.edu/projects/ORA/index.html.
