You have been assigned as the manager on a project to develop a new application system for your business partner. You were given two weeks to develop a project plan and high level cost estimates.

The system takes data feeds from three upstream applications, and sends information back to two of them. You have never worked with these three systems in the past, although one of your developers used to work in the group that supports one of them.
