Continuous planning
Publish the schedule weekly, three weeks before execution, so planning keeps pace with the business rather than happening once.
Replanning
Handle changes to an already published schedule without turning it upside down, and react to real-time disruptions within milliseconds.
Overconstrained planning
Plan even when there are too few resources to cover all the work, so the solver degrades gracefully instead of failing.
Pinning
Keep the user in control of the schedule by locking the parts of it that should not move.
