Project dependencies in the project portfolio

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.
