You are the head of the Information Technology Division and your company will be implementing a new enterprise resource planning system companywide over the coming weekend. Bringing the system online will entail a significant effort by your team together with the consultants, and you will need to shut down the system at 5:00 p.m. Friday to get started.

Since many people in your company work until 6:00 or 6:30, even on Fridays, and sometimes come in on the weekend, you need to inform everyone of the necessity to shut down the system at 5:00 on Friday. You believe this will enable your team to finish by midday on Saturday, with time to test and troubleshoot the system before Monday.
