Types of Dependencies in Project Management
Various types of dependencies exist, influenced by both internal and external factors. Below, we outline several primary categories of project dependencies.
Logical Dependencies
Referred to as causal dependencies, these dependencies constitute essential components for a project’s culmination. They often represent the ultimate output of all preceding tasks and cannot be concurrently pursued with other tasks. For instance, if you lack a team member, delegating a task to someone else becomes impossible. In this scenario, hiring an additional team member becomes a logical dependency.
Resource Dependencies
Resource-based dependencies come into play when two or more tasks necessitate the same resources for completion. Such resources may include team members, machine components, funding, or skilled professionals. For example, when you and the finance team require the hard drive containing this month’s reports, a resource dependency arises, necessitating a wait for one of the parties.
Preferential Dependencies
These dependencies typically hinge on team members, other stakeholders, and established industry practices. Preferential dependencies emerge when tasks are scheduled to adhere to established standard practices. While ignoring preferential dependencies may not impede project completion, it can lead to quality-related issues.
Quality-Related Dependencies
Quality-related dependencies form an integral part of the quality assurance process, relying on industry best practices or convenience. These dependencies are crucial for ensuring the quality and consistency of project deliverables.
External Dependencies
Certain elements of a project manager’s control are unaccounted for in the project plan—these are external dependencies. Erica Tahan, Digital Marketing Project Manager at WITHIN, frequently encounters external dependencies, particularly in client communications and requests.
Implementing project management software to facilitate client communication and accountability has streamlined processes, reduced the need for frequent meetings and extensive email exchanges, and fostered transparency in interactions with client points of contact. Features like task assignment, notification setup for impending deadlines, and automated reporting have significantly mitigated past dependency challenges and fostered improved relationships between internal teams and client stakeholders.
Types of Task Dependencies in Project Management
Comprehending and pinpointing the connections among task dependencies is a pivotal aspect of a project manager’s role.
Below are the descriptions of four distinct task dependencies in project management.
Finish-to-Start (FS)
In a Finish-to-Start dependency, Task B cannot commence until Task A has been completed. It represents a sequential relationship where one task must conclude before the next can begin.
Start-to-Start (SS)
A Start-to-Start dependency dictates that Task B cannot initiate until Task A starts. This type of dependency highlights tasks that need to move forward simultaneously. For instance, think of two construction teams coordinating their efforts to build different parts of a structure.
Finish-to-Finish (FF)
With a Finish-to-Finish dependency, Task A can only be considered complete once Task B concludes. This type of relationship ensures that two tasks, although distinct, must synchronize their endings. An example might be finalizing a project sale once the budget and timeline are finished.
Start-to-Finish (SF)
Lastly, the Start-to-Finish dependency signifies that Task B cannot be completed until Task A begins. This less common relationship entails that the initiation of one task triggers the completion of another. Imagine a scenario where you can only close a deal once negotiations have started.
- Finish-to-Start: Task A must finish before Task B can begin.
- Start-to-Start: Task B must start when Task A starts.
- Finish-to-Finish: Task B’s completion depends on Task A’s completion.
- Start-to-Finish: Task B can only be completed when Task A starts.
Internal Dependencies in Project Management
In project management, internal dependencies are key in shaping the path to project success. These dependencies encompass various categories, each influencing the project’s progression in its own unique way.
Here, we delve into the intricacies of internal dependencies, highlighting their key categories and providing illustrative examples.
Task-Based Dependencies
Task-based dependencies form the bedrock of project progression. They follow a logical sequence of tasks that must be completed in order. For instance, printing shipping labels precedes the mailing of customer orders, illustrating the sequential nature of task-based dependencies.
Team-Based Dependencies
Collaboration is often essential in project management, leading to team-based dependencies. These dependencies necessitate the cooperative efforts of different teams to achieve project milestones. An exemplary instance is the requirement to capture product photos for sales brochures, which hinges on the production team delivering a prototype for photography.
Approval-Based Dependencies
In some cases, project progress depends upon obtaining necessary approvals. Approval-based dependencies revolve around the need for official consent or authorization. For instance, the acquisition of large-scale manufacturing equipment necessitates approval from the Chief Financial Officer (CFO) before proceeding.
Best Practices-Based Dependencies
Certain dependencies are grounded in best practices that optimize task completion. Adhering to these practices ensures efficiency and quality.
Resource-Based Dependencies
Resource-based dependencies revolve around the availability of specific resources required to initiate a task. These resources can encompass materials, equipment, or other essentials. For example, printing sales brochures relies on the availability of the correct cardstock and ink.
Software-Based Dependencies
Software is key in project management. Software-based dependencies require software inputs or updates to facilitate task progression. Regular updates to storage software to ensure secure data access are a prime example of such a dependency.
Understanding and effectively managing these internal dependencies is essential for project managers to ensure the seamless flow of tasks, timely project completion, and attaining project objectives.
External Dependencies in Project Management
External dependencies present a distinct set of challenges and uncertainties. These dependencies are factors lying beyond the direct control of a business or project team, making them often unpredictable and demanding meticulous management.
Here, we explore the external dependencies, shedding light on their nature and providing noteworthy examples.
The Uncontrollable Variables
External dependencies encompass many factors that can significantly influence project outcomes. These variables are external to the organization but can exert considerable impact. Here are some common categories of external dependencies:
Deliveries
The timely arrival of materials and supplies is crucial for various projects. Supply chain disruptions, delivery delays, or material shortages can impede progress. For instance, commencing the construction of a product is only possible if the necessary materials have yet to arrive.
Traffic
Traffic congestion can disrupt the timely arrival of equipment, impacting project schedules. For example, setting up a trade show booth becomes impossible when essential equipment is stuck in a traffic jam.
Weather
In industries like construction, favorable weather conditions are important. Adverse weather events, such as hurricanes or storms, can stop outdoor projects and extend timelines. Building a house during a hurricane is not only impractical but also unsafe.
Finances
Financial dependencies, especially concerning loans and funding, can introduce delays. Initiating major purchases or investments may hinge on the availability of funds. When loan approvals or funding processes are timely, it can help the project’s progress.
Managing external dependencies requires foresight, adaptability, and contingency planning. Project managers must develop strategies to mitigate the impact of these external variables, fostering resilience and agility in the face of unpredictable circumstances.
