When your organisation is spread across multiple sites it can add great value to capture where an incident has occurred.
It may be that a user reporting an issue from one place, but the source of the issue is in another. In today's world of being more mobile, having remote access to systems, working from home, and hot-desking, this become more of a challenge.
Identifying the location of the issue can help assess who else may be impacted, who is the closest to the location to get it fixed, and where are the most problematic sites.
