Task dependency refers to the relationship of tasks in a project, where certain tasks can only begin or continue after other tasks have been completed. By defining dependencies among tasks, teams can clearly establish the correct execution order and avoid workflow confusion or scheduling conflicts.
In many projects, tasks are not independent but rather follow a specific sequence. For example, in an interior renovation project, demolition and site protection must be completed before electrical work, masonry, or waterproofing can begin. Similarly, in website development projects, design work often needs to be completed before the engineering team can proceed with development.
In projects with tightly linked timelines, defining task dependencies in advance helps team members clearly understand when they should start their work.
Setting up task dependencies help project managers:
These mechanisms help maintain a logical and consistent workflow even when the project schedules are adjusted.
Task dependencies become especially important when a project has the following characteristics:
In this scenarios, clearly defining task dependencies help ensure smoother project execution.
