The project is experiencing a delay in the development and installation of a new system due to staffing issues, with 50% of tasks still outstanding two days before completion. The impact on the project includes increased costs, delayed timeline, and potential quality issues. To address this issue, additional resources will be required, including hiring external experts. The schedule change will involve allocating responsibility within the hired professionals, estimating the cost and time for adjustments, and communicating with stakeholders. To monitor the deliverable, schedule tracking and weekly progress reports will be used, along with milestone achievements reported to the project manager.
