Project Insight uses intelligent scheduling to calculate task start and end dates based on predecessor relationships, task constraints, and schedule changes. When you move a linked task, change its duration, add or remove a dependency, or apply a constraint date, Project Insight recalculates the related tasks automatically.
Best for: Project managers and schedulers who want a connected project plan that adjusts dynamically instead of maintaining every task date manually in a spreadsheet.
How does Project Insight calculate task dates?
Project Insight calculates task dates from the relationships and scheduling rules applied to each task.
The intelligent scheduling process considers:
- Predecessor relationships
- Task duration
- Constraint types and constraint dates
- The project start date
- The task creation date for newly added tasks
Project Insight does this by treating the project plan as a connected schedule. When one task changes, the system recalculates the tasks affected by that change.
What predecessor relationships does Project Insight support?
Project Insight supports the standard task relationship types used in project scheduling:
- Finish to Start: The successor task starts after the predecessor finishes.
- Start to Start: The successor task starts after the predecessor starts.
- Finish to Finish: The successor task finishes after the predecessor finishes.
- Start to Finish: The successor task finishes after the predecessor starts.
These relationships determine how changes to one task affect the dates of another.
How can I see task predecessors on the Task List?
The Task List can display predecessor information in two ways:
- Predecessor by Number
- Predecessor by task name
These columns show which earlier tasks control the schedule of each successor task.

How do I see task relationships on the Gantt Chart?
Open the project Gantt Chart to view the predecessor relationships as lines connecting the task bars.
A simple sequence of linked tasks appears as a cascading schedule. Each task begins or finishes according to the relationship created with the task before it.
What happens when I remove a predecessor?
When you remove a predecessor relationship, Project Insight recalculates the task without that dependency.
The task may move earlier because it no longer has to wait for the former predecessor. Other related tasks may also move based on the updated relationship structure.
What happens when I add a predecessor?
Adding a predecessor can move the successor task later so it follows the newly connected task.
A task can also have more than one predecessor. Project Insight considers all of the relationships when calculating when the task can occur.
Project Insight does this by recalculating the earliest valid date that satisfies the task’s predecessor relationships and other scheduling rules.
How are new tasks scheduled in an active project?
A new task added to an active project does not automatically schedule itself in the past simply because the project started earlier.
By default, the new task uses the ASAP After Task Create Date constraint. This schedules the task as soon as possible after the date it was created.
Project Insight does this so a task created today is not assigned a start date from an earlier period when no one could have worked on it.
What is ASAP After Task Create Date?
ASAP After Task Create Date schedules a task as soon as possible, but not before the task was created.
This is useful when new work is added after a project is already underway. It keeps newly created tasks from automatically appearing in the past.
How is ASAP After Project Start different?
ASAP After Project Start allows the task to be calculated from the beginning of the project rather than from the task creation date.
Use this option when you want the task to behave like part of the original project plan, even if it was added later.
In short:
- ASAP After Task Create Date prevents a newly created task from scheduling before it existed.
- ASAP After Project Start calculates the task from the project start date.
What other task constraint types can I use?
The Advanced task settings include additional scheduling constraints, such as:
- As Soon As Possible
- As Late As Possible
- Start No Earlier Than
- Must Start On
These constraints let you control when a task can occur when predecessor relationships alone are not enough.
How do I change a task constraint?
- Open the task in the full task edit screen.
- Open the Advanced options.
- Select the constraint type you want to use.
- Enter a constraint date when the selected rule requires one.
- Save the task.
Project Insight recalculates the task and any connected work based on the new constraint.
What happens when I manually set a task date?
Manually setting a task date applies a scheduling constraint to the task.
For example, entering a specific start date can create a Must Start On constraint. The task remains on that date while Project Insight recalculates its relationships with other tasks.
A constraint indicator appears beside the task when a constraint date has been applied.
Can I set a task date by dragging it on the Gantt Chart?
Yes. Dragging a task bar to another date on the Gantt Chart can apply a constraint and reschedule the task.
Project Insight then recalculates subsequent linked tasks based on the new position.
How do I review or remove a task constraint?
Select the constraint indicator beside the task to review the constraint and its date.
From that area, you can remove the constraint. Project Insight will then recalculate the task from its remaining relationships and scheduling rules.
What happens when a task has both a predecessor and a constraint?
Project Insight considers both the predecessor relationship and the task constraint when calculating the schedule.
The task must satisfy the rules created by both settings. Removing the constraint may allow the predecessor relationship to move the task to a different date.
Can I remove all constraint dates?
Yes. If manually scheduled dates have created too many constraints, you can use the option to remove all constraint dates.
Project Insight then recalculates the schedule using the remaining task relationships and scheduling rules.
Use this carefully because removing all constraints can change dates throughout the project plan.
What happens when I move a linked task?
Moving a linked task later can move all subsequent tasks later. Moving it earlier can allow the later tasks to move earlier.
Project Insight does this by recalculating the schedule according to the dependencies that connect the tasks.
Where can I change task dates?
The tutorial shows that task dates can be updated from:
- The Task List
- The Gantt Chart
- Kanban boards
Regardless of the view used, Project Insight applies its scheduling rules and recalculates the connected project plan.
Does intelligent scheduling support sprints?
Project Insight also supports scheduling through agile sprints. However, the workflow in this article focuses on projects that are not using sprint scheduling.

Why is intelligent scheduling better than manually entered dates?
Manually entered spreadsheet dates remain disconnected unless someone updates every affected row after a change.
Project Insight uses task relationships and constraints to calculate dates dynamically. When one part of the project changes, related tasks can update automatically.
This helps teams:
- Reduce manual schedule updates
- Keep task sequences connected
- Understand how one delay affects later work
- Avoid scheduling newly created tasks in the past
- Use fixed dates only where the project requires them
- Maintain a project plan that responds to change
In short, Project Insight calculates task dates as part of a connected project schedule rather than treating them as independent values.
What should I check when task dates do not look right?
- Review the task’s predecessor relationships.
- Check whether the task has more than one predecessor.
- Look for a constraint indicator beside the task.
- Review the constraint type in the Advanced task settings.
- Check whether the task uses ASAP After Task Create Date or ASAP After Project Start.
- Confirm that task durations are accurate.
- Review the connected schedule on the Gantt Chart.
What are common mistakes when scheduling tasks?
- Assuming all new tasks will schedule from the project start date
- Manually setting many dates and creating unnecessary constraints
- Removing a predecessor without reviewing the resulting schedule
- Adding multiple predecessors without checking how they affect the task date
- Dragging a task on the Gantt Chart without realizing a constraint may be created
- Using fixed dates when a flexible predecessor relationship would be more appropriate
- Removing all constraints without reviewing the effect on the entire project
Related questions
Does Project Insight calculate task dates automatically?
Yes. Project Insight calculates task dates from predecessor relationships, durations, constraints, and other scheduling rules.
Why did a new task schedule today instead of at the project start?
The task may be using ASAP After Task Create Date, which prevents a newly created task from being scheduled before its creation date.
Can one task have more than one predecessor?
Yes. Project Insight considers all predecessor relationships when calculating the task date.
Does dragging a task change the schedule?
Yes. Dragging a task can apply a constraint and cause subsequent linked tasks to be recalculated.
Can I remove a constraint without opening the full task?
Yes. Select the constraint indicator to review and remove the constraint from the available task layer.
Can I clear all manually set constraint dates?
Yes. Use the option to remove all constraint dates, and Project Insight will recalculate the schedule from the remaining relationships and rules.
