The e3tool software allows the constructions of custom fraud scenarios based on any value model.
This is useful for analyzing more complex fraud scenarios, evaluating the financial impact of mitigation or countermeasures and conducting sensitivity analyses.
Step 1: Create an e3value model
Fraud assessment requires a value model of the networked business model being assessed. Please refer to tutorial on constructing value models for a brief introduction to the main concepts and basic model editor functionality.
Profitability and net present value analyses can be run on an e3value model (both available in the Tools menu). After the business model is fully understood, the next step is to assess the risk(s) that not all actors behave as expected.
Step 2: Attach fraud annotations
The following fraud annotations can be optionally added to a value model (thereby transforming it into a fraud model):
- Value transfers which do not take place can be marked by right-clicking and will show as dashed lines.
- Transfers can be marked as hidden, via the right-click menu, and will appear as dotted lines.
- Actors can be marked as colluding. They will then act as a single actor, pooling their budgets. This is represented using red highlighting. In the top rated fraud scenario of the flat-rate example, User A and User B are colluding.
These annotations are useful for differentiating between the expected (ideal) case and the fraudulent case.
Step 3: Analyze the fraud model
By running a Profitability analysis (from the Tools tab), one can visualize the financial effects of the fraud across a given occurrence range of a selected need.
