As an example, consider 2 activities A and B. A proper sequence of events taking into account dependencies might be as follows: 4. Discretionary Dependencies – These are “soft” dependencies that reflect how the team anticipates the work will be completed, or how the team “would like” the work to be completed.These types of dependencies enable the team to optimize the flow of work throughout the project life cycle. Below are three types of project planning dependencies: All dependencies should be captured into the defined dependency tool and MUST include who is responsible for delivering the dependency to the project. Grinding the coffee beans is a predecessor activity for measuring the coffee into the filter. You know that you need to complete the following tasks:
Dependencies can be classified in a number of ways based on criteria such as the causes behind them, predecessor-successor relationships, and whether the dependency exists between activities within the project or outside of it. Of course, there is a proper order to this process. If, for instance, a construction site requires 24/7 security services and there are a few guards working in shifts, the current shift cannot end before the relief security officers arrive, as the site would be left unattended.Dependencies can also be classified based on the tasks’ relationship to the project, as follows:Internal dependencies describe the relationship between two tasks or activities within the same project. The PM and the project team usually have complete control over these activities, and there is no involvement of any external parties.
You will be able to distinguish between these terms by the end of this post. Therefore, experienced PMs schedule regular meetings to discuss how the linked tasks are progressing, if there are any changes in schedules or requirements, and whether those changes impact the connection between project tasks.There is no substitute for good communication when it comes to effective dependency management, and there are two key elements experienced PMs pay attention to:Project dependencies are inevitable, but managers shouldn’t feel threatened by them. If B has an Internal Dependency on A then it would signify that both A and B are project activities. 1. But there is a difference between project dependencies, assumptions, constraints, and risks. Planning dependencies fall into three categories: logical, resource-based, or preference. The Main Types of Project Dependencies. For instance, before construction workers can start building, renovating or demolishing, it is first necessary to obtain approvals from local authorities.

In the case of external dependencies, such as a reliance on suppliers, someone within the project should be assigned to monitor the relationship with the supplier and ensure everything is on track.Having a log of all the details mentioned above will prove to be helpful during the project planning and scheduling process, allowing PMs to effectively sequence tasks and develop strategies to minimize and mitigate risks.While identifying and documenting dependencies is important, it is their constant monitoring and control that will ensure the successful delivery of a project. Otherwise, this logic might be forgotten over time or questioned by clients, executives or any other stakeholders who weren’t initially involved in the task-scheduling process.Based on the relationship between the initiation and completion of individual tasks, dependencies can be classified into four major types:The most common and logical predecessor-successor relationship is the Finish-to-Start dependency, while Start-to-Finish is the most rarely encountered and may be puzzling to envision. Until this has happened, there is no commitment that the dependency will be met. Imagine getting out of bed in the morning, yawning, and making your way to the kitchen to discover that you forgot to preset your coffeemaker to brew automatically.
While it is impossible to prevent all potential issues, with good organization, planning and communication, even the most complex projects can be kept under control.
When it comes to internal project activities, the task owner will usually be the natural dependency owner as well.
In a project network, a dependency is a link amongst a project's terminal elements. Project Managers reference project dependencies as the relationships between individual tasks in a project diagram. Project dependencies are often misconstrued as assumptions or constraints in project management. PMs and project teams don’t usually have much control (if any) over these dependencies.
