Managing, visualizing, and reducing dependencies are crucial tasks in agile project management and often fall within the purview of the Certified Scrum Product Owner (A-CSPO). Such dependencies can have a significant impact on project implementation. In this article, we will explore two techniques ideal for visualizing, managing, or reducing dependencies – the Design Structure Matrix (DSM) and the Dependency Wheel.
1. Design Structure Matrix (DSM)
The Design Structure Matrix (DSM) is a square matrix used to represent and analyze system elements’ interdependencies. The DSM approach assists in visualizing and analyzing dependencies within complex projects, thereby creating a more streamlined, efficient workflow.
There are two types of DSM – static and time-based. The static DSM is used to represent the relationship between project tasks, while the time-based DSM helps in managing project timelines.
Here’s how the DSM works:
- The tasks involved in a project are listed vertically and horizontally on DSM’s axis.
- Dependency is represented by marking the intersecting cells of the two tasks.
- Reading this matrix from top to bottom and from left to right will give you a clear picture of task sequences and dependencies.
This method promotes the ‘divide and conquer’ approach, segregating tasks into independent groups to mitigate risks and manage resources more effectively, thereby reducing dependencies between tasks.
2. Dependency Wheel
The Dependency Wheel, also known as a Dependency Graph, offers a graphical representation of dependencies within a team or system. It enables you to map out dependencies clearly, providing a comprehensive, at-a-glance view of interdependencies in real-time.
The dependencies are represented in circular format, with each task or component represented by a segment on the circle. The links between different segments depict the dependencies. The stronger the dependency between two tasks, the thicker the link between them.
The Dependency Wheel facilitates a clear understanding of how intricately tasks are linked, enabling a team to identify potential bottlenecks and minimize dependencies where possible. By providing a clear visual of how different tasks interact, the Dependency Wheel assists product owners and teams in making informed decisions about project planning, task sequencing, and resource allocation.
Conclusion
In conclusion, the Design Structure Matrix (DSM) and Dependency Wheel are two powerful techniques for visualizing, managing, or reducing dependencies in project management. By implementing these methods, Advanced Certified Scrum Product Owners (A-CSPO) can significantly enhance their ability to manage complex projects, facilitating better resource allocation, timely delivery, and ultimately, project success. These techniques underline the importance of understanding how tasks, teams, and resources interconnect – insight that is key to effective, efficient agile project management.

Interview Questions
What are the two main techniques of visualizing dependencies in Scrum?
Dependency Structure Matrix (DSM) and Visualization Mapping are two main techniques used to visualize dependencies in Scrum.
How does a Dependency Structure Matrix help in managing dependencies?
A Dependency Structure Matrix (DSM) provides a compact way to represent and navigate dependencies across multiple teams. It is a square matrix designed to specify the dependency information between different modules.
Can you explain what is meant by Visualization Mapping in the context of managing dependencies?
Visualization Mapping is a technique where dependencies are visually mapped out. It provides a visual representation of the relationships between various elements of a project, allowing for a clearer understanding and management of dependencies.
How can reducing dependencies aid in the product development process?
Reducing dependencies increases the speed and quality of feedback, reduces the amount of work in progress, increases team autonomy, simplifies planning, and reduces risks associated with the integration of work.
What are some approaches to reduce dependencies?
Techniques for reducing dependencies include: minimizing cross-team dependencies by promoting greater autonomy within teams, encouraging regular and open communication across teams, and promoting clean code practices to minimize technical dependencies.
How does creating a backlog and refining it help in managing dependencies in Scrum?
Creating and refining a backlog helps in identifying and understanding the dependencies between the tasks early in the project. By recognizing these dependencies, Scrum teams can plan accordingly and manage them effectively.
What role does a Scrum Product Owner play in managing dependencies?
A Scrum Product Owner communicates with stakeholders to identify dependencies, works closely with other product owners to coordinate and manage dependencies, and helps the team prioritize work taking into account dependencies.
How can we use the Scrum of Scrums approach to manage dependencies?
In the Scrum of Scrums approach, representatives from each Scrum team attend a coordination meeting to discuss dependencies and collaboration requirements. This helps manage dependencies between different Scrum teams in a larger organization.
How can Modular Design help in reducing dependencies in Scrum?
A Modular Design divides the system into separate components that can be developed independently and in parallel. This reduces dependencies as teams can work on separate modules concurrently, thereby reducing their dependency on other teams.
What role does clean code play in managing dependencies within the team?
Clean code practices involve coding in a way that minimizes cross-dependencies between different sections of the code. This makes the code more understandable and manageable, thus eventually reducing dependencies within the team.
How can continuous integration help in managing dependencies?
Continuous integration ensures that code is tested in a shared repository regularly. It helps eliminate the problems caused by dependencies by identifying integration problems and conflicts early in the process.
Why is the process of regularly checking code into a shared repository beneficial for managing dependencies?
Regularly checking code into a shared repository allows teams to spot and resolve integration problems as they arise. This process provides quick feedback on issues, allowing dependencies to be managed more effectively.
What is a feature team and how does it reduce dependencies?
A feature team is a long-lived, cross-functional, self-organizing team that completes many end-to-end customer features, one by one. Feature teams reduce dependencies as they can deliver end-to-end, valuable increments without having to rely on other teams.
How does the practice of frequent releases help manage dependencies?
By releasing increments of the product frequently, teams get faster feedback and can adapt their plans more quickly. Frequent releases also help to spot and solve dependencies early in the development process.
How can direct and clear communication within the team help manage dependencies?
Clear and direct communication ensures that everyone in the team has a shared understanding of the task at hand. It helps in discussing potential dependencies and finding solutions on how to manage them effectively.
