Predecessor and Successor Tasks:
A predecessor task is one that must be completed before its successor task can begin. This relationship ensures that project workflows are logically sequenced and tasks are completed in the correct order.
Predecessor: This is the task or phase upon which the subsequent task (the successor) is dependent. It acts as a blocker until it is completed.
Successor: This is the task or phase that relies on the completion of its predecessor to start. It cannot be completed until the predecessor task finishes.
Now, let's see what influences dates changes in,

1. Influences on Project Start and Due Dates:
Scenario 1: Project Creation
Manual Setup: When creating a project from scratch, you can manually set the start and due dates. This allows flexibility in aligning project timelines with business priorities and resource availability.
Template-Based Setup: Importing templates automates much of the project setup process. The due date of the project is typically derived from the last task's due date in the imported template, ensuring projects are scheduled efficiently.
Note: Once a project is created, changing the due date of the last task does not automatically adjust the project’s due date. This requires manual updating to reflect any changes in project scope or timeline.
Scenario 2: Importing Templates After Project Creation
Adjusting Due Dates: Importing templates with tasks extending beyond the current project end date adjusts the project’s due date accordingly. This ensures that the project timeline accommodates all required tasks and milestones.
Example: If a project is initially due on June 1st and an imported template extends its tasks by 10 days, the new project due date becomes June 12th (excluding weekends). If the template's tasks fit within the original deadline, no adjustments are necessary.
2. Influences on Phase Start and Due Dates
In Rocketlane, phase start and due dates are influenced by several factors, ensuring alignment with task dependencies and project timelines:
Default Behavior:
By default, Rocketlane determines phase dates based on the earliest start date of its tasks and the latest due date among them. This ensures that phases encompass all necessary tasks within their defined timeframe.
Scenario 1: Automation Enabled
When workflow management (avatar>settings>workflow management) automation is enabled, phase dates automatically adjust to align with the earliest and latest task dates. This can increase or decrease the phase duration.
Example:
Suppose a phase originally starts on June 1st and ends on June 30th. If the first task’s start date is adjusted to June 3rd, Rocketlane will automatically shift the phase start date to June 3rd to maintain alignment with the earliest task’s date. This adjustment also applies if the due date of the last task changes, impacting the phase’s end date to update to the latest task’s date. Additionally, any tasks dependent on those with updated dates will also be adjusted to preserve task dependencies and project sequencing.
Scenario 2: Tasks moving outside boundary
Boundary Adjustment: Regardless of automation settings, Rocketlane automatically updates phase dates if any tasks are moved outside the phase start and end dates.
Example:
Suppose a phase is scheduled to start on June 3rd. If the start date of the earliest task within this phase is moved to June 1st due to project requirements or task dependencies, Rocketlane will adjust the phase start date accordingly to June 1st. This ensures that all tasks are logically contained within the phase timeline.
Similarly, if a phase is set to end on June 30th and the due date of the last task is extended to July 1st, Rocketlane will automatically shift the phase’s end date to July 1st. This adjustment maintains coherence in project scheduling, aligning phase durations with updated task timelines.
By automatically adapting phase dates to accommodate task movements, Rocketlane supports efficient project management, ensuring tasks are executed within their designated phases while maintaining clarity and alignment in project timelines.
Scenario 3: Dependencies
Dependency conflicts in a finish-to-start relationship occur when
the due date of the predecessor phase is later than the start date of the successor phase, or
when the start date of the successor phase is earlier than the due date of the predecessor phase.
In Rockeltane, a finish-to-start dependency can be established between phases. When there is a conflict between phases, the system automatically updates the phase dates to resolve the conflict. This adjustment ensures that the start date of the successor phase is set to one day after the due date of the predecessor phase.
3. Influences on Task Start and Due Dates:
Scenario 1: Dependencies
Dependency conflicts in a finish-to-start relationship occur when
the due date of the predecessor task is later than the start date of the successor task, or
when the start date of the successor task is earlier than the due date of the predecessor task.
In Rockeltane, a finish-to-start dependency can be established between tasks. When there is a conflict between tasks, the system automatically updates the task dates to resolve the conflict. This adjustment ensures that the start date of the successor task is set to one day after the due date of the predecessor task.
Scenario 2: Phase Shifting
When you drag and move the entire phase in the timeline view, all task dates within the phase will adjust accordingly to stay within the phase duration.
4. Influences on Parent Task’s Start and Due Dates
In Rocketlane, the start and due dates of parent tasks are directly influenced by the alignment of their subtasks. Here’s how it works:
Subtask Alignment:
The dates of subtasks must remain within the start and due date boundaries defined for their parent task. If any subtask’s dates extend beyond these boundaries, Rocketlane automatically adjusts the parent task’s dates to encompass the earliest start date and latest due date of its subtasks.
Example:
Consider a parent task, Task A, scheduled to start on June 1st and end on June 5th. Task A contains two subtasks. If the due date of the second subtask is updated to June 8th, exceeding Task A's original end date of June 5th, Rocketlane will automatically extend the due date of Task A to June 8th. Similarly, if the start date of a subtask is set to May 31st, Rocketlane will adjust the start date of Task A accordingly to May 31st to ensure all subtasks fall within the parent task’s timeline.
