External Tasks in Project Management – Definition and Meaning
External tasks are tasks, activities, or milestones that are outside the scope of the current project and are the responsibility of other teams, departments, or organizations, yet have a direct impact on the progress or success of the project. They are used to account for dependencies on other, often parallel, projects or external deliverables within the project plan. External tasks typically become relevant in multi-project environments or programs and are integrated into the project schedule to manage interfaces.
Example, best practice and further information
In an IT implementation project, an external task might be the timely provision of a required server infrastructure by the central IT infrastructure team. A best practice is to actively monitor external tasks on which the project depends and ensure coordination with those responsible. This aligns with interdependency management according to the PMBOK Guide and agile practices for cross-team coordination. It ensures that the project proceeds smoothly and that critical external dependencies are taken into account.
