Abstract: Embodiments of this invention relate generally to updating a project plan in accordance with an input. A user may have a limited set of privileges to update the project plan compared to a manager. The manager may provide a threshold value relating to a type of change that may be made to a master version project plan. Next, the user may access the master project plan, and provide an input relating to a proposed change. From the change, a change value may be derived, and the change value may be compared to the threshold value to determine whether the change value violates the threshold value. If the change value violates the threshold value, a change exception may be generated, and the manager may be notified that the proposed change requires review. If the change value does not violate the threshold value, then the master project plan may be immediately updated.
