According to the latest update of the project schedule, you realize that the project will be completed one month after the desired completion date. You have extra resources on hand and the activity dependencies are preferential. The project is not of high risk and the SPI up to now is 0.89. As a project manager, what would be your best course of action under these circumstances?
Leveling the resources would generally increase the project duration. Removing the activities under some conditions and using the project change process (discretionary dependency) might be possible but considering that dependencies are preferential and you have extra resources the first thing could be to make more activities concurrent.
