I am a fairly new IT director at this organization. I am designing a new infrastructure and I am adding services. I would like to know if anyone has references for IT department sizes. I had a proposal to hire a network admin and a Systems admin on top of the help desk person that I already have. The Executive staff is questioning my proposal and they feel all they need is another help desk person. They want me to manage all the services. We are an organization of 100 people. Our organization runs our own conferences and we are a membership based business. Besides the basic services of Email and Internet, we will be running Share point , communication server, Oracle, MS SQl for Great Plains, E-commerce, VoIP, Web conf and Wireless.

What are their concerns ? Have you already communicated the targeted benefits ? Is it possible to mesure those ? It seems that the most important thing for your Executive staff is the endusers benefits, do you have some problems on the part of this team ? Too ticket number are hold ? If the endusers benefits should be increased, find a solution to increase on that and don't forget other needs...

a good solution is to rely on Benchmarks. i personnaly used either Compass or Mercer in the past, but as your company is merely big enough, the answer won't be probably signficant (one figure answer). Size of development teams are unpredictable as too much business related, but infrastructure team can be reasonably sized.A template may assist (copy the XML below in Excel).

In my humble Opinion , i do not think you need a network and a system administrator. A very good network administrator can work as a system administrator . If the network is properly set up with the right policies implemented at the server and firewall levels. the network admin can manage so many things remotely.
My fear is that you will need a database administrator for the MS SQL / ORACLE server .

suggestion : hire one network admin to do system adm , manage sharepoint, communication server E- commerce , voIP , web conf and wireless infrastructure .

If i can have the breakdown of the intended job funtions for the two people on your proposal , i can see how i can re-arrange to hire minimum number of personnel.

drop a mail to aedward@ecomarinegroup.com
i will be glad to help more.

As the company y're working for has just 100 employees, it won't be the number of users that will give you a headache. It will be more into the number of different servers and services that you run next to availability of these systems/services.

As long there is a 9 to 5 availability request it won't be much of a problem to run it with, to the max, 3 co-workers, being y're helpdesk person, yourself and one network/system admin. This is if you yourself can coop with the databases.

If availability shifts to a more wider range you will have to put in more personnel or outsource the non 9 to 5 tasks. Basics here are if it becomes a 24x7 availability then you will need for every person with a task of the 9 to 5 operations, at least, 3 extra persons, totaling 4 for every task, as days off (weekends) and other "vacation? like days have to be covered by this.
Then there is your own job. As it won't be a 24x7 job you still have to consider that there has to be an upscale emergency path to inform management when having trouble.

As you say that you are designing a new infrastructure I guess you don't have deep knowledge off databases. So you will have to consider hiring a DBA.

If needing some extra help or clearance please do mail me.

Rob
