In multi-project management, several projects run in parallel, often competing for resources or strategically linked to one another. One of the biggest challenges here are project dependencies - i.e. relationships in which the progress of one project directly or indirectly influences the progress of another.
Types of project dependencies
- Logical dependencies: Project A must be completed before project B can start
- Resource dependencies: Projects share resources, budget or infrastructure
- Strategic dependencies: A project provides the basis for a downstream, strategically important follow-up project
Why are project dependencies critical?
- Delays in a project can trigger a chain reaction
- Lack of transparency leads to wrong decisions when prioritising or allocating resources
- Without active dependency management, there is a risk of overlapping deadlines and budget problems
Best practices in dealing with project dependencies
- Centralised overview: A centralised system that makes all dependencies visible is essential
- Regular reviews: Recognising and evaluating effects on other projects at an early stage
- Collaboration support: Cross-departmental communication helps to recognise bottlenecks early on

Conclusion
Having project dependencies under control increases efficiency and reduces risks across the entire project portfolio. Tools such as PlainPPM are a decisive success factor here.
