What you will need…

In the course of working through a CRAFT project, you likely will create a variety of diagrams, text, tables, and data, in addition to the specific risk-assessment models created as part of the effects analysis. CRAFT also provides several on-line tools to help with your analysis; including GIS Viewers, the CRAFT Wizard and CRAFT Project Portals (See the following pages for more information on each of these tools).

There are several requirements that will be needed for your CRAFT project.

  1. Create an organizational chart or other hierarchical diagram needed to display an objectives hierarchy. For example, Microsoft Word® and Powerpoint® have this capability.

  2. Draw conceptual diagrams. Box-and-arrow or other flow diagrams can be useful to build and display conceptual models. Work with tables and forms on-line. CRAFT's question-based Wizard asks users to enter responses via web-based forms.

  3. Store, manipulate, and display data for the group to share. Any popular spreadsheet, relational database, or statistical package should work.

  4. Probabilistic modeling requires the most specialized software. Bayesian Belief Networks or influence diagrams provide the most accessible means of such modeling, but other approaches are possible.

CRAFT's examples and tutorials are based on Netica®, developed by Norsys. Other belief network and decision analysis applications—many free—are widely available. One of the more sophisticated and friendly of the freeware applications is GeNIe, available from the Decision Systems Laboratory at University of Pittsburgh. Hugin Expert® is a premier commercial product, but is expensive. Analytica® provides a more general and versatile modeling environment than Netica but lacks some of Netica's more desirable features such as diagnostic reasoning.
