You are a busy professional. You don't have time to devote to looking for your manager but you need an answer so you can move your project forward. You check her calendar and find it's booked for the day. You look in her office, she's not there. So you become the hunter, stalking your manager, trying to find where she is in the building for one quick discussion. All you need is 3-minutes of her time to talk, not even a 15-min meeting. If only you both had Impromptuu. You could set a priority alert and as soon as she was on the move, instead of wasting your valuable time trying to find her in the office Impromptuu rings you both. And voila, you talk and get the answers you need. Problem solved.
