Dependencies between projects are defined by adding dependencies between milestones within the projects.


When you add a dependency between two milestones, you set if the dependency is a before or after dependency. 



For example if software development has to complete before user training create two milestones for each activity. Add a dependency between the milestones and set the software development dependency to be before user training. If the software development milestone moves after the user training milestone an error will be raised.



First add or select a milestone on the planner or roadmap. This is the milestone you are linking from.


Select the dependencies link.



A list of milestones you can link to will be displayed. 


Select add.




Select either before or after to create the link between the milestones.




Milestones with dependencies are indicated with a link icon.




Any projects with invalid dependencies show a warning flag.




Any milestones with invalid dependencies are indicated in the dependency warning area on the left of the planner.



And within the roadmap.
