Functions and Risks 
A risk is an object that associates two or more conflicting functions.
A function is a grouping of one or more actions.
When you define a risk, you specify a combination of functions that represent a risk to an employee.
Note
The definition of a risk includes other attributes that impact how the risk translates into rules. The condition that determines the presence of a risk is one or more functions that when combined, create a conflict.
Actions assigned to a function represent the tasks an employee must be able to perform for a specific purpose.
However, combined functions can conflict.
Example
An employee who has access to inventory records, should not have the authority to sign for deliveries. When these two functions are combined, they pose a risk.
