You and a small group of managers from the sponsoring organization have just completed defining the scope, schedule, and cost for an important project in your firm. You estimate that the project will take 12 people about 10 months and cost just over $2.5 million. You just received an email from your manager insisting that the project schedule be shortened by three months because senior management is impatient for the improvements this project is expected to deliver. He promises to "free up" four additional resources within the next month or so to be assigned to your project. How do you respond?
