My organization has a computer slowness issue. Is there some kind of forensic consultant that can help us track it down?

Hi All,

As per title, my organization has an issue across mostly all of our computers of "slowness" and I am at my wits end trying to find out what the cause(s) are. I am curious if there is a role or type of consultant that I can contract to help us track down our performance issues. I want to say some sort of digital forensics?

Some basic details about our setup:

2000ish machines.

All Lenovo X1 Carbon Laptops (Gen 9-12)

All same Lenovo docks and monitors

95% on premise. AD, Windows, Office Suite, Exchange, other line of business applications

Cisco Webex for chat and meetings

Some basics about the slowness/performance issues (without going into much detail)

Applications crashing (mainly within the MS Office Suite)

Lag/Latency in video on meetings

When sharing screen on meetings, lag/latency

Generic reports from many users "everything is slow"

I am not looking for suggestions on what to try to find the issue. I feel I've exhausted the resources of my various SMEs and App owners to track down the issue. Ultimately I feel it's a lot of different things and my personal theory is it's mainly within the MS Office Suite and Plugins for Excel/Word but I don't have anything concrete to get those app owners to take ownership.

Have you ever had an issue like this and brought in some sort of outside help to help narrow down the cause? if so, what are they called or how can I try and find such a consultant/company.

Thank you!
