From the Clarity PPM Project Management User guide:
Dependency relationships can exist between one investment and another in your portfolio. Use the Properties: Dependencies page for the investment to identify this relationship.
Dependencies can occur between the start and completion of conflicting work effort, or from budget overruns. From this page, you can do the following tasks:
■ Add investments with dependency constraints.
■ Indicate if these investments are dependent on your investment or if your investment is dependent on them.
Follow these steps:
1. Open the project.
2. Open the Properties menu, and from Properties, click Dependencies.
3. Select a mode to view or add the following:
■ Investments that depend on this one.
■ Investments this one depends on.
4. Click Add to add more dependencies to your investment.
5. Select an investment type from the Type drop-down, select an investment, and click Add.
