Dependencies

Definition: Dependencies in project management refer to the relationships between tasks that determine the order in which project activities should be performed.

Dependencies are critical in project scheduling and management. Understanding and managing dependencies is essential for creating realistic project timelines and ensuring that the project progresses smoothly without unnecessary delays.

Types of Dependencies in Project Management

In project management, there are various types of dependencies:

• Finish-to-Start (FS): A task must finish before the next one can start.

• Start-to-Start (SS): A task must start before or simultaneously as another task starts.

• Finish-to-Finish (FF): A task must finish concurrently with another task.

• Start-to-Finish (SF): A task must start for another task to finish.

Recognizing and correctly identifying these dependencies helps project managers to establish a logical sequence of activities and manage the critical path effectively.

Related Terms/Concepts

• Project Timeline: The schedule that outlines when tasks, including dependencies, are to be completed to ensure the project progresses smoothly.

• Milestone: Key points that may depend on the completion of specific dependencies before they can be considered achieved within a project.

• Resource Allocation: The process of assigning resources in a manner that accounts for the dependencies among tasks, ensuring efficient project execution.

• Project Charter: A document that may outline significant dependencies that could impact the project's scope, timeline, and resource requirements.

• MoSCoW Method: A prioritization technique that can help manage dependencies by identifying which tasks are must-haves versus could-haves, thereby assisting in effective project planning and execution.

Frequently Asked Questions About Dependencies

Why Are Dependencies Important in Project Management?

Dependencies are important because they dictate the order in which tasks are completed, impacting the project schedule, resource allocation, and the overall timeline.

How Can Dependencies Affect Project Risk?

If dependencies are not properly identified and managed, they can lead to bottlenecks, delays, and increased project risk. Effective dependency management is critical to mitigating these risks.

Can Dependencies Exist Between Projects?

Yes, dependencies can exist between different projects, especially when they share resources, have interconnected deliverables, or when one project's output is required for another project to commence. These are often referred to as interproject dependencies.
