Track Key Milestones and the Critical Path
Background
Milestones represent significant points in time, such as "Substantial Completion" or "Building Dried-In." By toggling the Critical Path view, you can see if these milestones are at risk due to delays in preceding tasks.
Things to Consider
-
Critical Path Definition:
-
Native Schedules (Option 2): Activities with zero float.
-
Imported Schedules (Option 1): Definition provided by the source file (P6 or MS Project).
-
-
Lookahead Limitation: The Critical Path toggle is disabled in the Lookahead tab as it is derived strictly from the master schedule.
Steps
Create a Project Milestone
-
Navigate to the Scheduling tool.
-
Create a new activity row or select an existing one.
-
In the Duration column, type "0" and press Enter.
-
Note: The Gantt bar will transform into a diamond-shaped icon, indicating a milestone.
-
View the Critical Path
-
In the top-left control toolbar, locate the Toggle Critical Path button.
-
Click to enable the view.
-
Note: All activities and milestones on the critical path will be highlighted in red.
-
-
Analyze the red path to see which activities must be completed on time to prevent the project finish date (and final milestones) from shifting.
Toggle Logic Visibility
-
If the screen is too cluttered to see the path clearly, click the Toggle Dependencies button to hide or show the relationship arrows.
-
Use the Views button to ensure Logic Constraints and Dependencies are visible on the Gantt bars for deeper analysis.
