Modern projects rarely move in isolation. Most delivery timelines are a chain of interdependent tasks, where the start or completion of one activity directly impacts another. In our previous release, we introduced Critical Path Management with Circular Dependency Control, enabling teams to identify schedule risks and bottlenecks with greater predictability.
In this release, Orangescrum takes dependency management a step further with Task Predecessor and Successor support — giving project teams precise control over how tasks relate, sequence, and progress across complex project plans.
This blog explains what task predecessors and successors are, why they matter for critical execution, how Orangescrum supports all dependency types, and real-world use cases across PSU, government, and IT-enabled services projects.
What Is a Task Predecessor and Successor?
In any structured project plan, tasks are rarely standalone.
Task Predecessor
A predecessor is a task that must start or finish before another task can begin or complete.
Task Successor
A successor is a task that depends on the predecessor and follows it in the execution flow.
In a chain of tasks:
The task before is the predecessor
The task after is the successor
For example:
“Requirement Approval” → predecessor
“Development Start” → successor
This relationship becomes especially critical when managing milestones, regulatory approvals, phased rollouts, and compliance-driven work.
