Velocity is one of those over-used terms you often see in business. It's intended to convey a sense of urgency or intensity when talking about time-to-market, time-to-quota, time-to-beat-out-the-competition.
Problems occur, however, when it is used to excuse incomplete or otherwise ineffective communications. Messages start ricocheting everywhere like pinballs, hitting everything but their targets. Sure they have "velocity" but they have no mass; they carry no weight.
So they fizzle out.
It's counter-intuitive, but taking time to communicate speeds progress. Your messages stick better. You repeat yourself less. Tuned to your audiences, your accuracy improves and you waste less time restating, clarifying, qualifying.
Less can be more for your team, too. Being peppered with messages distracts their effectiveness. Sending fewer targeted messages raises everyone's game and delivers the higher overall velocity you're looking for.
