While discussing a project that will take at least 15 business days with an engineer and my coworker and he is pushing for hard dates, his manager needs it done by the end of the quarter and that is fine. This requires some coordination between myself and my coworker and my coworker is on call this week.
"Is there any reason we can't just start this now?"
Sure let me drop all my other planned work and meetings today to work on this thing that needs to be done 6 weeks from now.
