Advanced Velocity Usage

We are running our agile projects well and have a good idea of our team velocity. However, we have some issues from management, who thinks that a velocity number is a way to taunt other teams to higher performance. 
How can we convince them that this is a number unique to each team and to each project?

A.	Management usually has a different set of driving motivators, and therefore unless you educate them they will not understand that measuring by velocity already allows teams to speed up and produce better quality to its maximum ability.
B.	Velocity is figured per person, as some individuals are better educated and more talented than others. Management should understand that a team without your team’s stars can’t work as fast.
C.	When teams figure velocity, they are just guessing. Pressure to meet the standards set by other teams will increase productivity and give the organization more value for their money.
D.	Ignore management and other customer leaders who want to know details about your progress. Tell them a finish date and make sure you deliver everything as planned. Witch one is the correct answer? by Barbee Davis, MA, PHR, PMP, PMI-ACP
