Bright Hub: Is having multiple operator systems a bad idea? And does this present more problems for an IT person, or does making a slow move to a new system such as Vista solve some problems?
David Kelleher: Although using multiple operating systems can be problematic, it is not so much the systems in themselves that create problems but the technical abilities of the person implementing the technology. Sticking to one operating system, especially in an SMB, makes it much easier for the IT administrator to manage, upgrade and troubleshoot. Not all SMBs have more than one administrator and more often than not that person would be versed in one, and maybe familiar with another operating system at the most. Unless IT staff are confident managing different OS, an SMB faces a high risk of downtime as issues crop up that may take longer than normal to troubleshoot.
The key to a successful network deployment is to prepare and carefully analyze the needs of the organization. Without a proper plan that takes into consideration not only the hardware requirements of the organization but even the staff and technical ability to manage the network, an SMB will be asking for trouble or a very steep learning curve.
In terms of OS upgrades, to Vista for example, the decision will depend on whether it is a must or not. If a company is managing fine with Windows XP and Windows Server 2003, upgrading to Vista and Server 2008 will not be important or necessary (there are cost issues to look into as well). Migration to a new OS should only take place if it will solve recurring problems and will lead to an overall improvement in how the company operates in terms of networking and security.
Bright Hub: Do you think that it is better for an SMB to have a full-time IT person or would it be better to hire an outside contractor?
David Kelleher: There are advantages and disadvantages in both situations. The primary concern is cost. Can a company afford to employ a full-time IT manager and is the volume of work such that it requires his or her services on a daily basis? If yes, then it makes sense to have an in-house IT administrator. On the other hand, if the company is small enough to only require occasional troubleshooting and maintenance it may be more cost effective to outsource their IT needs and purchase a maintenance agreement. Most contractors will respond to support calls within a couple of hours. The second option makes sense if the contractor was responsible for setting up the network.
