Problem
You are the PM on a software upgrade project. You find out from a senior team member that the project is starting to get out of control due to certain employees performing unplanned overtime, misunderstandings of the project's deliverable, and changes being made to the original plan without any oversight. Discuss what documents, tools, and/or processes could help to get the project under control or could have prevented it from getting out of control in the first place. When discussing documents, try to indicate specific sections that would be beneficial to reference.
