CPU usage high
If you notice a virtual server has high CPU usage over a prolonged period of time, aside from automatically assuming the server needs more CPU resources, what else should an admin do to get to the root cause. Can any other admin actions identify and rectify the root cause of high CPU usage, without having to scale up CPU resources for the system. These servers are running at over 89% CPU usage consistently during working hours.

Hyper-V or VMware? Also, what CPUs does the host have? I've experienced this issue with Hyper-V on older hardware.

Check performance of the VM. Establish a base line, what function does the Server perform ?

Thanks for the comments. Can you explain a "hung process" in laymans terms. What causes them?
"hung process" - when an application or service stops responding, maybe caused by a bug, software issue.
In a concurrent user environment, when many users are logging on and off a server, it's fairly common.
e.g. have you never used a desktop computer, and it becomes non-responsive, and you have to restart ?
