Working with Schedule Dependencies

While building your project schedule and associated levels, you can set up relationships between the phase, task, and labor code work breakdown structure (WBS) elements. These relationships are called dependencies.

You can structure dependencies logically, so that certain WBS elements rely on the start or completion of other elements before they can be accomplished. Establishing schedule dependencies makes it possible to do the following:
  • Quickly understand project schedule and relationships by viewing the Gantt chart without having to read through dates.
  • Efficiently update the project schedule when dates change on a project, since all of the impacted successor dates will automatically update as well (not just the parent/child relationships).
  • Track your project's critical path and overall schedule and identify potential schedule risks.
  • Understand which dates can change without impacting the project completion date.

Schedule Tab of Project Planning

Use the Schedule tab of Hubs > Projects > Plan to set up dependencies between WBS elements. This tab provides an interactive Gantt chart that displays a timeline for each level on your project plan's WBS. This provides a quick way to work with the project schedule, levels, relationships between the levels, and critical path.

For an overview of how to use the Schedule tab of the Plan form, see Creating Dependency Relationships Quick Reference.

You can create dependency relationships between WBS elements on the Schedule tab in these ways:
  • Drag the arrows between bars on the Gantt chart.
  • Use the Dependency Details dialog box. To display this dialog box, either double-click a bar or click on the row tools () for the level and select Dependency Details.
  • Type the predecessor details in the Predecessor column.

See Create Dependency Relationships for more details on how to use each method.

When you create a dependency, an arrow from the predecessor to the successor displays. If you change the dates for a predecessor, all successor dates change accordingly. Any updates you make on the Schedule tab automatically update the corresponding information on the Labor, Expenses, Consultants, and Units tabs.

Dependency Indicators on Other Project Planning Tabs

After schedule dependencies are created on the Schedule tab, the Labor, Expenses, Consultants, and Units tabs of Project Planning and Resource Management applications display a in the Has Successor or Has Predecessor columns on the row to indicate that the WBS element has a dependent relationship.

Create Schedule Dependencies

This video shows you the different methods for creating schedule dependencies on the Schedule tab of Project Planning. These methods allow you to identify predecessors and successors, select relationship types, and add lag/lead time for dependencies.
