One of the most important strategies of effective branch-office management is simply knowing what you’re managing. It sounds pretty basic, but many IT executives haven’t identified and categorized their branch-office inventories.
As I outlined last week , Nemertes has identified the branch-office market as a four-tier structure - including headquarters it’s a five-tier structure:
Tier One
Number of users: 500 or more
Bandwidth: High (typically OC-3 and greater, sometimes T-3), very large concentration of employees, access to all applications
Typical types of sites: Headquarters, data center
Tier Two
Number of users: 301 to 1,000
Bandwidth: High (T-3 and greater), large percentages of employees, access to all applications
Typical types of sites: R&D facilities, large contact centers, largest regional offices
Tier Three
Number of users: 51 to 300
Bandwidth: Relatively high (multiple T-1 to T-3), significant concentration of employees or important executive's individual
office, access to all applications
Typical types of sites: Mid-size branch offices, distribution facilities, midsize contact centers, CEO or executive home office
Tier Four
Users: 2 to 50
Bandwidth: Lower (T-1, or cable modem/DSL), small concentration of employees, access to most applications
Typical types of sites: Small branch offices, retail sites, manufacturing facilities
Tier Five
Users: 1
Bandwidth: Lower (56Kbps to -T-1 or cable modem/DSL); individual offices, access to some applications
Typical types of sites: Telecommuters, mobile workers
Let’s look at some of these tiers and the challenges organizations face when they’re trying to manage them, starting with
Tiers Four and Five.
Tier Five sites often are the most difficult to manage. First, there are a lot of them. The average company has 1,100 telecommuters — a number that, depending on company size, ranges from 1 to 25,000, according to Nemertes’ latest Convergence benchmark. Each telecommuter is another location, so it increases the actual number of sites network and IT staffs must manage often by orders of magnitude!
Couple that with the fact that telecommuters and mobile workers typically are alone. They don’t have a tech-savvy colleague who can step into the office or hotel room and fine-tune an application, troubleshoot a cable modem or BlackBerry, or figure out why the wireless link isn’t working.
