I'm currently deploying websites and Google Apps for Business for a parent/umbrella company "UmbrellaCorp" which owns several (ten or so) other subsidiary companies in retail clothing, construction, IT Services etc. All companies are separate legal established companies/entities even though they are under the same parent umbrella company.
I would like help to plan management of the umbrella company's domain name and how to properly feature the subsidiaries' websites (subdomains of umbrellacorp.com - subfolders or separate domains?) and how to deploy Google Apps for Business for all employees.
What is the best practice regarding email addresses?
Use full names or work titles?
The companies are not internet savvy startups, they are more conventional with B2B word-of-mouth corporate clients. Hence a full blown website and branded email addresses for every company/employee is not so important, a simple information page on the umbrella website would do.
