What is a Dependency?
Definition of Dependency
A dependency refers to a unidirectional relational reliance and timing between two product initiatives where an entity requires full or partial completion of an originating predecessor before efficiently contributing business value representing hierarchy constraints requiring proactive coordination actions to optimize project sequence.

In the realm of Product Management & Operations, the term 'Dependency' holds a significant place. It refers to the reliance of one task, process, or function on another to achieve a specific outcome. In simpler terms, a dependency in product management & operations is a condition where the performance or completion of one task is contingent on the performance or completion of another task.

Dependencies can be internal or external, and they play a crucial role in shaping the operational efficiency, project timelines, and overall success of a product. Understanding and managing dependencies is a key skill for product managers and operations teams. This article will delve deep into the concept of dependency, its types, its role in product management and operations, and how to effectively manage it.

Understanding Dependency

Dependency is a fundamental concept in project management and operations. It is the logical relationship between two or more activities or tasks in a project. In other words, it is a condition where the start or finish of one task is reliant on the start or finish of another task.

Dependencies can be a result of various factors such as resource availability, technical requirements, legal constraints, or strategic decisions. They can impact the project schedule, cost, and quality, making it essential for project managers and operations teams to identify and manage them effectively.

Types of Dependencies

Dependencies can be broadly categorized into four types: Finish-to-Start (FS), Start-to-Start (SS), Finish-to-Finish (FF), and Start-to-Finish (SF).

Finish-to-Start (FS) is the most common type of dependency. In this case, the dependent task cannot start until the task it depends on is complete. For example, in a software development project, the coding phase cannot start until the design phase is complete.

Start-to-Start (SS) dependency implies that the dependent task cannot start until the task it depends on has started. For example, in a manufacturing process, the assembly of a product cannot start until the parts are procured.

Finish-to-Finish (FF) dependency means that the dependent task cannot finish until the task it depends on is complete. For example, in a marketing campaign, the evaluation phase cannot finish until the execution phase is complete.

Start-to-Finish (SF) is the least common type of dependency. In this case, the dependent task cannot finish until the task it depends on has started. For example, in a training program, the evaluation phase cannot finish until the training phase has started.

Role of Dependency in Product Management & Operations

Dependencies play a critical role in product management & operations. They can impact the project schedule, cost, quality, and risk, making it essential for product managers and operations teams to manage them effectively.

Dependencies can affect the project schedule by causing delays. If a task that other tasks depend on is delayed, it can delay the entire project. Similarly, dependencies can increase the project cost. If a task that other tasks depend on is more expensive than anticipated, it can increase the overall project cost.

Dependencies can also affect the project quality. If a task that other tasks depend on is not done to the required quality, it can impact the quality of the entire project. Lastly, dependencies can increase the project risk. If a task that other tasks depend on is risky, it can increase the overall project risk.

Managing Dependencies in Product Management & Operations

Effective management of dependencies is crucial in product management & operations. It involves identifying, analyzing, and controlling dependencies to ensure that they do not adversely impact the project.

Identifying dependencies involves determining which tasks depend on each other. This can be done through techniques such as brainstorming, interviewing, and document analysis. Once the dependencies are identified, they need to be analyzed to understand their potential impact on the project. This can be done through techniques such as risk analysis, cost-benefit analysis, and impact analysis.

Controlling dependencies involves taking action to minimize their potential impact on the project. This can be done through techniques such as scheduling, resource allocation, and risk mitigation. For example, if a task that other tasks depend on is delayed, the project manager can reschedule the dependent tasks to minimize the impact on the project schedule.

Specific Examples of Dependency in Product Management & Operations

Dependencies are ubiquitous in product management & operations. They can be found in various processes such as product development, supply chain management, and customer service.

In product development, dependencies can occur between different phases of the product lifecycle. For example, the testing phase cannot start until the development phase is complete. Similarly, the launch phase cannot start until the testing phase is complete.

In supply chain management, dependencies can occur between different entities in the supply chain. For example, a manufacturer cannot start production until the raw materials are delivered by the supplier. Similarly, a retailer cannot start selling a product until it is delivered by the distributor.

In customer service, dependencies can occur between different functions. For example, a customer service representative cannot resolve a customer's issue until the technical team fixes the problem. Similarly, a customer service manager cannot evaluate a representative's performance until the customer feedback is received.

How to Identify and Manage Dependencies in Product Management & Operations

Identifying and managing dependencies in product management & operations can be a complex task. It requires a systematic approach and the use of appropriate tools and techniques.

One of the most effective ways to identify dependencies is through a Dependency Structure Matrix (DSM). A DSM is a square matrix that represents the dependencies between different tasks in a project. The rows and columns of the matrix correspond to the tasks, and the cells of the matrix indicate the dependencies. A cell is marked if there is a dependency between the tasks corresponding to the row and column of the cell.

Once the dependencies are identified, they need to be managed effectively. This can be done through various techniques such as Critical Path Method (CPM), Program Evaluation and Review Technique (PERT), and Gantt charts. CPM and PERT are mathematical algorithms that help in scheduling tasks based on their dependencies. Gantt charts are graphical representations of the project schedule that help in visualizing the dependencies between tasks.

Managing dependencies also involves regular monitoring and controlling. This can be done through status reporting, progress tracking, and risk management. Status reporting involves regularly updating the stakeholders about the status of the dependencies. Progress tracking involves regularly checking the progress of the dependent tasks. Risk management involves identifying and mitigating the risks associated with the dependencies.

Conclusion

Dependency is a critical concept in product management & operations. It refers to the reliance of one task on another to achieve a specific outcome. Dependencies can be internal or external, and they can impact the project schedule, cost, quality, and risk.

Understanding and managing dependencies is a key skill for product managers and operations teams. It involves identifying, analyzing, and controlling dependencies to ensure that they do not adversely impact the project. Effective management of dependencies can lead to improved operational efficiency, better project outcomes, and increased customer satisfaction.

As the realm of product management & operations continues to evolve, the importance of managing dependencies effectively is likely to grow. Therefore, it is essential for product managers and operations teams to continuously enhance their skills and knowledge in this area.
