Creating a Calculated Property

Calculated properties are used to create a property that is based on a range of values. This procedure will walk you through creating a calculated property named Custom Risk with three classifications: Low, Medium, and High. We will use the internal property Risk and a custom property named Impact of type Number (you should create this one in advance).

  1. Click Requirements > Requirement Properties .
  2. Click New Calculated Property.
  3. In the Name field, type Custom Risk.
  4. In the Description field, type Calculated property using Risk and Impact (L, M, H).
  5. Select Business Impact from the Insert Property list. ${Business Impact} is added to the Formula field.
  6. Select * from the Insert Operator list. ${Business Impact}* is added to the Formula field.
  7. Select Business Risk from the Insert Property list. ${Business Impact}*${Business Risk} is added to the Formula field.
  8. On the default row of the Classification grid, rename the entry to Low. Since all calculated properties must contain a default classification without a lower bound, this one will be used.
  9. Click Add Classification. A new row is added to the Classification grid.
  10. Name the classification Medium and add a Lower Bound of 10.
  11. Click Add Classification. A new row is added to the Classification grid.
  12. Name the classification High and add a Lower Bound of 20.
  13. Click OK.
A calculated property is now created that will be populated with Low, Medium, or High when both the Impact and Risk properties are set for a requirement.
