Understanding project dependencies in project management contexts

What is a project dependency?

A project dependency refers to a relationship between tasks where the completion or initiation of one task is reliant on the completion or initiation of another. Dependencies are crucial for maintaining order and ensuring a logical flow of activities throughout a project’s lifecycle. If you are using a project management software, most applications have dependencies as a built-in feature. You can use them on your projects to create relationships between tasks.

What are the different types of project dependencies?

To effectively implement project dependencies, it’s important to understand the different types of dependencies at your disposal. Different project dependencies include the following:

Finish-to-start dependencies

Finish-to-start dependencies are the most common type. In this scenario, Task B cannot start until Task A is completed. For example, painting a room (Task B) cannot begin until the walls are prepared (Task A)—creating a sequential relationship.

Start-to-start dependencies

Start-to-start dependencies involve the initiation of two tasks simultaneously. Task B can only begin when Task A starts. An example would be planting seeds in a garden (Task B) concurrently with preparing the soil (Task A).

Finish-to-finish dependencies

Finish-to-finish dependencies involve the completion of two tasks simultaneously. Task B can only be completed when Task A is finished. An example would be two teams collaborating on different sections of a report, both needing to finish for the overall project to conclude.

Start-to-finish dependencies

Start-to-finish dependencies mean that Task B can only be completed when Task A starts. This scenario is less common but may be applicable in situations where the start of one task signifies the end of another. For example, once you implement a new accounting system you can turn off the old one.

Benefits of dependencies in project management

Dependencies can improve how an assignment is completed, between team members and approximating how long an assignment will take. Benefits of dependencies include:

Improved coordination and efficiency

Dependencies facilitate a structured sequence of tasks, maximizing coordination, task prioritization, and overall efficiency. With a clear understanding of task relationships, teams can work cohesively towards project goals.

Effective resource allocation

By recognizing dependencies, project managers can allocate resources more effectively. Tasks dependent on others can be scheduled accordingly, preventing any scheduling obstacles, and ensuring optimal resource utilization.

Accurate project scheduling

Dependencies contribute to more accurate project scheduling. By mapping out task relationships, project managers can create realistic timelines and set achievable milestones, fostering a sense of accomplishment among team members.

Dependencies are a logical project management tool to optimize workflow. Dependencies ensure tasks are completed in order, improving efficiency, effective resource allocation, and accurate project scheduling. Add this tool to your project management wheelhouse and ensure your projects are completed on time, accurately, and to the specifications of your client.
