Project dependencies in the project portfolio

In multi-project management, several projects run in parallel. They often compete for resources or are strategically linked. One of the biggest challenges is project dependencies – relationships in which the progress of one project directly or indirectly affects the course of another. 

Types of project dependencies

• Logical dependencies: Project A must be completed before project B can start
• Resource dependencies: Projects share staff, budget, or infrastructure
• Strategic dependencies: One project lays the foundation for a strategically important follow-up project

Why are project dependencies critical?

• A delay in one project can trigger a chain reaction
• A lack of transparency leads to wrong decisions on prioritization or resource allocation
• Without active dependency management, you risk scheduling conflicts and budget problems

Best practices for managing project dependencies

• Central overview: A central system that makes all dependencies visible is essential
• Regular reviews: Identify and assess the impact on other projects early on
• Encourage collaboration: Communication across departments helps you spot bottlenecks early

Conclusion

When you have project dependencies under control, you increase efficiency and reduce risk across your entire project portfolio. Tools like PlainPPM are a key success factor.
