I’m curious to know what industry you work in, what version of SharePoint you are using, and how many users are in your network?
I work in higher education. Our internet is on SP 2010 and we will be launching our Intranet in August using SP 2013. We have 38,000 faculty, staff and students.
The past few years, I worked for 2 MNCs, both in the manufacturing industry. As I was working in/for the region Asia Pacific, my user base was smaller, I think around 600 / 2000 users respectively. Versions were 2007 and 2010
I just joined a consultancy, though, focussing mostly on Office 365, but of course still with the occasional on-premises SharePoint.
