Task Dependencies In Project Management (All You Need To Know)

Task Dependencies In Project Management

Task dependencies in project management”. I’m sure that this phenomenon is nothing new for project managers and their teams. However, if you’ve just started in the domain of project management then you need to understand project task dependencies in detail. 

The domain of project management and human life have one common scenario – interdependence of various activities to meet our needs and build momentum to progress.

Whether it’s a small, straightforward project or a large, complex project, there will be a sequence in which tasks are supposed to be completed. Most (if not all) of these tasks are dependent on each other. 

You’ll rarely come across a project in which all tasks are independent of each other. 

This article is composed with the intention to help you understand what are task dependencies in project management, their vitality, their types, examples, and how to manage them effectively to deliver a project successfully. 

Read on to know all about it.

What is task dependency in project management? 

Inter-dependent tasks in project management are those that rely on each other to be performed (completely or partially) before the next one could be started. Where there’s a task dependency, there’ll always be preceding and successive tasks; the latter depends on the former. 

This can also be termed as a logical or preferential relationship between two activities or tasks. Let us take a look at some examples to easily understand this aspect of project management. 

Examples of task dependencies in project management

Given below are some simple examples to exemplify the concept for beginners who are still coming to terms with project management and team collaboration

Example 1: Content Creation And Approval

Content is the King in the domain of digital marketing but you cannot create and post content straightaway. You need a trending or evergreen topic to create content, proofread it, get it reviewed and approved, and then post it on your website (or on another platform). This way, one activity is dependent on the other. 

You cannot start with an article or a blog until you finalize a topic. Once the topic is approved you create a draft and get it reviewed. Now, if the content is not approved during the review process, it will not be allowed to publish, and so on. So, you can see that all these tasks are dependent on each other.  

Why do we need task dependencies in a project?

The task or project dependencies are crucial to its overall success. A project manager needs to set task dependencies to: 

  • Define the sequence of tasks in a project plan
  • Figure out the critical path of tasks (how long each task is expected to take to be completed)
  • Identify required resources and potential scheduling issues 
  • Monitoring and managing tasks within the project plan
  • Avoid conflicts of scheduling
  • Making adjustments in case of lags or advances

How Constraints And Project Task Dependencies Are Directly Correlated 

A constraint is a bottleneck or setback within the scope of an in-progress task.

These restrictions can be internal, like a lack of adequate resources in the form of money and a skilled workforce. Let’s say you need to assemble 10 PCs in a day but you only have one technician who cannot put together more than 5 PCs in a day. To assemble 10 PCs in a day, he would need additional tools to speed up the process.

Here, constraints are the lack of tools with the technician, and the task of assembling all 10 PCs in a day is therefore dependent on the technician’s ability to do it. 

Constraints can also be external. For example, if you’re planning to get your house repainted, you need to hire a paint contractor to get the job done. Without it, you cannot start with your repainting project.  

The aforementioned examples show that the constraints have given birth to the dependencies and vice-versa.  

What are different types of project task dependencies

Project planning dependencies establish relationships among predecessor and successor tasks. There are different types of task dependencies in project management, which are listed below. 

  • Causal Dependencies

Causal or logical task dependencies cannot be avoided. These dependencies occur naturally in the flow of tasks within a project. Without completing one task, you cannot initiate the next task in any way.  

  • Resource-Based Dependencies

Resource-based task dependencies are constraints-driven. There is no causal dependency, which means that all tasks and activities can be completed together if all required resources are available. 

  • Preferential Dependencies

Preferential dependencies are driven by optimal practices or convenience. Preferential dependencies focus on the quality of deliverables and are determined by the project manager and the project team.  

  • External Dependencies

External task dependencies are those dependencies that are beyond the control of project managers and teams. External dependencies rely on third parties or outside vendors for completion.  

  • Cross-Team Dependencies

Cross-team dependencies exist when two or more teams are required for delivering an end-to-end project. These dependencies present a stiff challenge to larger organizations. 

  • Finish To Start (FS) Dependencies 

This is probably the most common type of project task dependencies used in project management. In this case, task B depends on task A to get started. If task A is not completed satisfactorily then there’s no chance of task B getting started. For example, you cannot watch a football match in a stadium unless you buy a ticket first. 

  • Finish To Finish (FF) Dependencies

FF task dependencies in project management mean that the successor task cannot be completed until the predecessor task is completed as well. For example, laying asphalt must finish before lane painting can be completed. 

  • Start To Start (SS) Dependencies

SS task dependencies in project management mean that the successor task cannot be started until the predecessor task has begun. Two tasks need to start simultaneously. For example, a car race cannot start unless all cars have started racing. 

  • Start To Finish (SF) Dependencies

SF task dependencies in project management are least frequently used. This means that the predecessor activity can only complete once the successor task has been initiated. For example, employees working in a day-shift cannot wrap up unless employees working in a night-shift are present at work.

ProofHub gantt charts

Use Gantt charts in ProofHub to have greater control over teams, projects, and resources easily. Gantt charts are designed to meet the needs of any organization irrespective of its size. These charts can be simple or complex, based on the nature of work your team is doing.  

Gantt charts help you get a clear picture of all tasks, their progress, who’s working on what to make well-informed decisions, avoid bottlenecks, and manage resources efficiently. 

Using Gantt charts, you can visualize and plan tasks, stay on top of your schedule, set task dependencies, and adjust your plans as work changes and deadlines shift. Read on more to discover how you can use Gantt charts to smartly manage task dependencies. 

  • Gantt charts help you visualize tasks in a timeline view so you can see the bigger picture and know how all tasks are progressing. You can push your workforce to deliver more if some tasks appear to be running behind schedule
  • Add tasks and task lists to Gantt charts, and plan and schedule the order in which you want tasks to be completed 
  • Assign tasks or subscribe the entire task list to an individual or multiple people. Everyone knows who is supposed to work on what tasks, and by when
  • Set dependencies between tasks and adjust schedules as work changes and deadlines shift
  • Associate milestones with tasks and mark important dates such as desired completion dates and project review meetings on the project plan
  • Track task progress in percentage to check how much work has been completed and how much is left
  • Create private tasks lists in the Gantt chart to limit visibility only to selected people
  • Drag and drop tasks in the Gantt chart to quickly change their start and due dates or duration
  • Highlight critical path to see the status of tasks that directly affect the start and end date of a project

Custom workflows and kanban boards 

Kanban board for design team

Besides the Gantt chart, another useful tool in ProofHub for managing task dependencies in project management is Kanban boards. What makes these boards efficient for handling task dependencies are its core principles – visualizing tasks at hand and seeing work moving through multiple stages. 

According to a report, 90% of information that enters our brain is visual, and our brain processes visuals much faster than text. An additional benefit of visualizing workflow in Kanban boards is that it makes constraints and dependencies visible. 

Another feature of Kanban boards that makes it easier to manage task dependencies in project management is managing lead time i.e. the time it takes for a single task to get completed, from the start to finish.
An unfavorable lead time can be attributed to long work processes and restrictions in the process. A Kanban board enables project managers and team members to visualize the work status and process constraints.  

Dealing with task dependencies in project management with kanban boards

When it comes to managing task dependencies, there’s no one size-fits all approach. Many businesses combine different methodologies to serve their purpose. However, the Kanban offers a versatile way to tackle dependencies. 

  1. Identify All Project Dependencies And Constraints

A visual tool like Kanban boards allow you to visualize workflows, better understand your work processes, identify complicated work stages, and get an overview of your workload. You may need to divide tasks into manageable subtasks so that the work continues to progress as planned. Once you identify potential project constraints, you’re in a better position to take required preemptive actions. 

  1. Annotate Tasks

After identifying different task dependencies and restrictions, annotate tasks with the names of tasks that depend on it and ones it depends on. Knowing the sequence of requirements helps you and your team members ensure that all tasks are carried out in a consistent stream. 

  1. Prioritize Tasks

Prioritize tasks based on schedules as some tasks become more relevant around specific dates. You can move such tasks lower or up on a scheduling calendar, depending up on their due dates. 

  1. Customize Workflows

Project managers can customize the Kanban board by adding more columns to 3 basic columns of a standard workflow – to-do, in-progress, and done. You can also add horizontal swimlanes to view and track tasks dependencies in project management. This is useful in case you have a lot of external dependencies that are beyond your control. 

  1. Record And Monitor Continuously 

You can track each task dependency within a project to make sure that tasks are progressing while improving processes. You can track 4 things: total work in progress, blockers, throughput, and the lead time. Having this information will help project managers plan and schedule efficiently while minimizing risks.
