Project Dependencies: How to Manage Dependency Effectively

project dependencies


Are you struggling to keep your projects on track? One of the key factors that can make or break a project is understanding and managing its dependencies. Project dependencies refer to the relationships between tasks or activities within a project, where the start or completion of one task depends on the successful completion of another.

In other words, certain tasks cannot be started or completed without first addressing their dependencies. Understanding and effectively managing project dependencies is crucial for ensuring smooth workflow and timely delivery.

In this article, we will explore the world of project dependencies and various aspects of it such as types of dependencies, identifying and mapping them, managing dependencies in project planning, allocating resources, setting timelines, and promoting effective communication and collaboration.

So let’s dive in and unravel the mysteries behind project dependencies!

What Are Project Dependencies?

Project Dependencies

Project dependencies play a crucial role in determining the relationships between tasks or products within a project. By definition, they refer to the dependencies that exist when a specific task requires the completion of another task or set of tasks before it can begin.

In this article, we will explore the significance of project dependencies and the need to understand their management.

Project dependencies can be illustrated through various examples. For instance, in baking a cake, the act of preparing the icing and baking the cake can occur simultaneously, representing independent tasks.

However, baking the cake is dependent on preheating the oven beforehand, establishing a clear dependency between these two tasks. Similarly, in content marketing, publishing a piece of content is reliant on the writers’ team delivering appropriate content for it.

Understanding Key Terms Related to Project Dependencies

Before delving deeper into the subject of project dependencies, it is essential to familiarize ourselves with key terms associated with this topic. Understanding these terms will provide a foundation for comprehending the intricacies of dependency project management.

Predecessor & Successor

Predecessor & Successor

In project management, predecessors are tasks that come before a specific task in a project schedule. Successors, on the other hand, are tasks that come after a specific task. Predecessors and successors help establish task sequences and dependencies, ensuring that tasks are executed in a logical and efficient order to achieve project goals.



Constraints are inherent restrictions within project management that dictate how tasks and projects should be completed. These constraints typically encompass factors such as cost, project scope, and time. Project dependencies can arise due to these constraints, as they set boundaries within which managers must operate.

Lead and Lag

Lead and Lag

Lead and Lag are two commonly used terms in relation to project dependencies. Lead refers to the amount of time by which a succeeding task can be advanced concerning the preceding task.

This concept applies specifically to tasks connected through a ‘finish to start’ relationship. For example, if Task B is scheduled to start when Task A completes in six days, but Task A finishes in three days, Task B will have a lead time of three days.

Conversely, Lag represents a delay in the start of a succeeding task due to a delay in the completion of the preceding task. Lag is undesirable as it can result in project delays and hinder overall progress.

Float (Slack)

Float (Slack)

Float, also known as slack, in project management refers to the amount of time that a task can be delayed without causing a delay to subsequent tasks or the project’s overall completion date. It represents the flexibility within a project schedule. There are two types of float:

  1. Free Float: This refers to the amount of time a task can be delayed without affecting the start date of its succeeding task.
  2. Total Float: This is the amount of time a task can be delayed without impacting the project’s final completion date.

Float is a critical concept in project scheduling, as it helps project managers understand the degree of flexibility in their project timelines. It allows for better resource allocation and risk management, enabling project teams to optimize schedules without compromising the project’s overall objectives.

Critical Path

Critical Path

The critical path refers to the sequential chain of task or activities that directly lead to project completion. Any delay or disruption in a task along the critical path can impact the entire chain of events and ultimately affect the project deadline. Identifying and managing the critical path is crucial for project success.


Blockers are obstacles or hindrances that impede the timely completion of tasks and projects. These blockers might be internal, originating from within the organization, or external, arising from factors outside the organization. Addressing and overcoming blockers is essential for maintaining project momentum and meeting deadlines.

By familiarizing ourselves with these key terms related to project dependencies, we gain a better understanding of the concepts and challenges involved in managing dependencies within a project. Constraints, lead and lag, critical path, and blockers play significant roles in project execution and require careful consideration for successful project delivery.

Types of Project and Task Dependencies (With Example)

Types of Project and Task Dependencies (With Example)

Having explored the concept of project dependencies and key terms associated with them, it is crucial to understand the different types of dependencies that exist in project management.

These dependencies vary based on internal and external factors that influence project execution. In addition, we will also discuss the significance of task dependencies within projects.

Logical Dependencies

Logical or causal dependencies are integral to project management and cannot be avoided. These dependencies occur when tasks have a logical sequence and cannot be performed simultaneously. The completion of a preceding task is necessary before the succeeding task can begin.

Example: Publishing a blog on a website requires it to be written, reviewed, and edited before it is ready for publication.

Resource-based Dependencies

Resource-based dependencies arise when multiple tasks require the same limited resources for completion. In this type of dependency, one task is dependent on the completion of another due to resource constraints.

Example: Two teams need to conduct team meetings, but there is only one meeting room available. Team B must wait for Team A to complete their meeting before they can use the room.

Discretionary Dependencies

Discretionary dependencies, also known as preferred or soft logic dependencies, are not essential for project completion but can enhance the quality of project deliverables. These dependencies are based on the discretion of project teams, stakeholders, and industry best practices.

Example: A blog may undergo review and editing by a content manager before being forwarded to the marketing team for publishing. Although the review process is not mandatory, it ensures error-free content and improves the overall quality of the published blog.

Cross-team Dependencies

Cross-team dependencies commonly occur in large-scale organizations where teams from different departments collaborate to complete a complex project. In such cases, teams depend on each other to achieve a common goal of timely project completion and delivery.

Example: The Chief Marketing Officer collaborates with the digital marketing and content teams to create factually accurate and well-researched content. The digital marketers check the content for structure and SEO friendliness before it is published.

Task Dependencies

Understanding task dependencies is equally important within a project. Task dependencies refer to the relationships and sequencing of individual tasks within a project.

Internal Dependencies

Internal dependencies occur when two tasks or activities within the same project are dependent on each other. These dependencies are under the complete control of the project team and do not involve external parties.

Example: The Quality Analyst team cannot begin testing software until the development process is completed.

External Dependencies

External dependencies are beyond the control of the project team and involve factors outside the project. Non-project activities are performed by external parties, such as clients, vendors, or other external groups, which impact the progress of the project.

Example: A project team cannot start working on a project until they receive approval from the client, who is an external party.

Hard Dependencies

Hard dependencies are rigid and inflexible relationships between tasks. They indicate that the start or finish of one task is directly dependent on the start or finish of another task. In other words, a task cannot start or be completed until its predecessor task is finished. Hard dependencies are often essential and non-negotiable due to technical requirements, safety considerations, or inherent task dependencies.

Example: In construction, pouring the foundation (Task A) must be completed before erecting the walls (Task B). Task B has a hard dependency on Task A.

Understanding Task Dependencies in Project Management

Understanding Task Dependencies in Project Management

Task dependencies play a crucial role in project management, determining the relationships and sequencing of tasks. By understanding the different types of task dependencies, project managers can effectively plan and execute projects, ensuring smooth workflow and successful outcomes.

Finish to Start (FtS)

This is the most prevalent task dependency, where Task A must be completed before Task B can begin. It represents a sequential relationship.

Finish to Finish (FtF)

Task B cannot be finished until Task A is completed. This type of dependency often applies to tasks with subtasks.

Start to Start (StS)

Task B cannot start until Task A begins. This dependency is suitable for tasks that need to be executed concurrently.

Start to Finish (StF)

Task A cannot be finished until Task B starts. This dependency is essential when there needs to be overlap between tasks. It might involve a specific lag time between starting one task and finishing the other.
