Dependencies are everywhere.
It’s only human to depend on other things or people.
Like depending on your morning coffee ☕ to become functional.
Similarly, projects and tasks also have their own set of dependencies. They help you define the relationship between activities to help you attempt them in the right order.
But what are Gantt chart dependencies, and how can you use them?
In this article, we’ll learn about Gantt chart dependencies and their various types. We’ll also show you how to manage Gantt chart dependencies using a great productivity tool.
Let’s get started.
What Are Gantt Chart Dependencies?
Dependencies are relationships between two tasks or activities, where the completion (or start) of one task is dependent on the completion (or start) of another.
Usually, task dependencies are represented on a Gantt chart, which is a kind of bar chart used in project management.
But apart from dependencies, Gantt charts also help you visualize the:

4 Types Of Dependencies Used In Gantt Chart
Generally, there are four types of dependencies that you can use to identify a task relationship:
1. Finish to start (FS)
The FS dependency is the most naturally occurring one.
Here, the successor task can’t begin until the predecessor task is complete.
For example, let’s say you’re renovating your home. You have to create a design plan (task A) first, or you can’t start renovating (task B).
2. Finish to finish (FF)
In this dependency or task link type, the successor task can’t conclude unless the predecessor task is finished too.
For example, you can’t pay the plumbers and carpenters (task B) unless they complete their job mentioned in the contract (task A).
3. Start to finish (SF)
This dependency type is rare.
Here, you can’t complete the successor task unless the preceding task has started. However, the successor task can complete anytime after the predecessor task has started.
For example, you can’t finish moving in your new furniture (task B) until the renovation (task A) has started. Once you’re done renovating, you can take your time to move in the new furniture.
4. Start to start (SS)
In this dependency, the successor task can only start after the predecessor task has started.
For example, you can start sticking the wallpaper (task B) only after you start applying the glue to the wall (task A).
How to set and track dependencies?
You now understand the different dependencies, but how do you set and track them?
We’ve got just the tool for you.
ClickUp offers you three different types of task dependencies:
- Waiting on
- Links to
And don’t worry.
They’re much simpler than figuring out which dependencies are FF, SF, SS, etc.
Let’s see how.
If a task needs another task to be completed before it, then just set it as waiting on dependency.
For example, you need to add a milestone to your project timeline. So set it as waiting on. Add tasks like approval from the marketing team or stakeholders as the tasks it’s waiting on.
If a task needs to be completed for other tasks to begin, then set it as a blocking dependency. For example, unless the project timeline is complete, the project can’t begin. So you can add multiple tasks the project timeline task is blocking.
Additionally, the link to dependency works best when different tasks aren’t exactly dependent on each other but definitely are related.
And as a bonus, there’s no way to mess up your collaboration, thanks to the incomplete warning. This warning is triggered when anyone tries to close a task with a dependency.
Now let’s find out how easy managing Gantt chart dependencies can be in ClickUp.
How To Manage Dependencies In A Gantt Chart?
The internet may tell you to use a Gantt chart template or create one for yourself in Microsoft Excel.
This is how you’re supposed to handle that situation:
If you don’t walk away from such suggestions, you may end up spending a lot of time and effort doing what ClickUp can do with just a few clicks.
Let’s see how you can use this powerful project management software to manage Gantt chart dependencies.
Step 1: Create a Gantt chart
Creating a Gantt chart with dependencies has never been easier.
In ClickUp, it takes just three clicks to do this.
And that’s it. You’ve successfully created a Gantt chart.
After you’ve created your Gantt chart, you can select what data you want to view from the chart’s task bar on the side.
Choose your tasks from Lists, Spaces, or Folders to add them to the Gantt chart.
Step 2: Schedule all your tasks
In ClickUp, all your scheduled tasks show up on the Gantt chart by default.
So if you’re missing a task or subtask, it’s because you didn’t schedule it.
Let’s change that right away.
You’ll find all your unscheduled tasks listed on the sidebar of the Gantt chart. You can even add a new task from the sidebar to schedule it.
All you have to do is place your cursor on the same lines as the unscheduled task on the Gantt chart and click on the date you want to schedule it.
ClickUp also lets you adjust the task start date and due date from the sidebar.
Note: Since we all need some time off, you can choose to hide weekends. If you do this, any task scheduled on the weekend gets automatically rescheduled to the next working day, that is Monday.
Step 3: Set, reschedule, or delete dependencies
Setting dependencies can sound like a super intense task.
And we don’t blame you.
Task A is dependent on Task B. Task C is dependent on A. Task D is dependent on B and C…
However, it’s actually not that intense when you can visualize it.
And most importantly, it’s a lot easier when you’ve got ClickUp to help.
ClickUp’s Gantt chart is super easy to use, thanks to its powerful drag and drop functionality.
Powerful enough to set and reschedule task dependencies in seconds.
Let’s see how.
You just need to draw lines between tasks on the Gantt chart, and ClickUp will automatically set it as a dependency!
Now let’s talk about rescheduling.
For this, ensure that “Reschedule Dependencies” is enabled under the View Settings or that drag and drop rescheduling won’t work.
So first, do that.
Now you can easily drag any task with dependencies to a new date without worrying about messing up the other task dates, dependencies, or the timeline.
That’s because when you drag such a task, ClickUp will automatically reschedule all the subsequent tasks in the dependency chain.
Relieved to hear that?
What if you need to reschedule an entire group of tasks?
Nothing complicated at all!
Just drag and drop the entire group on the Gantt chart without messing up your timeline. The start date, end date, or due date of all your tasks will be readjusted accordingly.
Note: If your task dependency consists of subtasks, remember to enable ‘Remap Subtask Due Dates.’ This way, when you change the due or task end date of a parent task, ClickUp can automatically remap your subtasks by the same amount of time.
Task dependencies can often change during the course of a project.
Sometimes they need to be rescheduled, which you already know how to do.
But other times, they just become irrelevant, so you need to delete them.
To do this in ClickUp, all you have to do is hover over and click on the dependency line. Then select delete.
Oh, we know what you’re thinking.
What if you delete a dependency by mistake while hovering the cursor?
Don’t worry. You will always receive a warning before deleting a dependency.
Unless you hit delete, nothing will go poof. 💨
Step 4: Find the critical path
Some projects will finish on time, while others may have hiccups.
This can be a problem because…
Before you panic, this is exactly where calculating the critical path comes in handy. This shows you only the essential tasks you need to do in order to complete your project.
We’ve already established that things are never complex on ClickUp.
So it goes without saying calculating the critical path on our Gantt chart will be a piece of cake. 🎂
All you need to do is spot the “Path Calculations” icon like it’s shown in the image below.
And then toggle on “Critical Path.”
You probably noticed “Slack Time” under “Critical Path” in the image. That shows you areas where you can adjust your tasks without impacting the project completion date.
Step 5: Share the Gantt chart with stakeholders
Your project may have people like clients, external stakeholders, etc. that aren’t part of your workspace.
If they can join ClickUp, that’s perfect.
We’re always happy to have new members.
But if they can’t join, don’t fret.
Instead, say hello to public sharing!
It allows you to share your Gantt chart view as a read-only version that can be accessed using a secret link.
Step 6: Track dependencies
The only thing left to do is to track your dependencies.
The Gantt chart view already gives a lot of visual data regarding:
- The project timeline
- Every dependent task
- The critical path
No, you don’t need to add dependencies again.
The views are flexible, so when you switch, all the set dependencies show up.
In the List view, you can even create a dependency column to display your dependencies that way!
Additionally, tracking things on our Gantt chart is like a fun game of spotting things. Here’s a quick game of I spy. 🔍
- Yellow diamond, that’s a milestone
- Blue task, it’s active
- Green task, it’s complete
- Red task, it’s urgent
Oh, and if you want to know how much you have left, just hover your cursor over the bar, you’ll know your progress percentage!

Drag And Drop Your Way To Project Planning
Gantt chart dependencies are ingenious.
You can set, track, rearrange, and visualize them right from the chart.
But only if you have the right project management tool for it.
An Excel template will not let you move things around easily with formulas.
And free online Gantt chart templates aren’t very flexible.
The only tool that gives you flexibility, shareability, security, and customization is ClickUp.
This powerful productivity and Gantt chart software let you create tasks, set task duration, and assignees, plan projects, and so much more. Not to forget, you can create a Gantt chart for multiple projects in ClickUp with just three clicks.
All that’s left to say is:
