In terms of the scalability, it seems like there is a lot you can do. It is customizable but it is somewhat limited in terms of how granular it can be, how can it be customized.

BMC FootPrints Service Core is scalable. I am unsure about how many users we have, but we have 40 licenses. 

None.

It can be scaled up as big as you want. It all has to do with just space, memory and the proper processors.

In Australasia (mostly comprised of Australia and New Zealand), I don't know how many end-users there are exactly. We maybe have 50 to 70 user companies currently. In New Zealand, they use this as their service base and they've got 40,000 to 50,000 employees and it is widely used. From that, you can see it can be scaled up easily.

No issues encountered.

We are satisfied with the scalability. We use an IBM mainframe, and we can discover it, and it supports many kinds of platforms. This solution is very scalable and it's good for large enterprises.

We have approximately four thousand users.

Scalability is probably very limited in terms of packages offered. It could be better for sure.
