There has been a lot written in the past few years about outsourcing technical support and SaaS (software as a service). It is not an easy choice for a company to make. On one hand, dumping all of your IT issues on someone else may save a few dollars and headaches. On the other hand, you do not always have control over the type of support your company receives–costing you more in the long run.
While many companies are using SaaS, many other companies do not. It is easy to get caught up in the latest trends, but trends are just that, and they are not always permanent. I have had the priviledge to work with a lot of major U.S. companies and while I can not say whether outsourcing is a true fad or not, I can tell you, imperically, that 75% of my contacts keep everything in-house. So do not be swayed by all of the tech media and exposure of recent trends. There is a place for both internal and external IT support. I guess it all comes down to cash flow: which one can I afford right now, and which one will be better in the long run?
