Depending on the size of your organization, you may want to consider subscription based support for your software as the need of your business calls for it. For example, if you run a larger company you cannot afford to have down time on your network and you must have immediate response time for any failures. On the other hand, if you have a smaller company and you don’t have the resources and have to be cost effective, you can resort to community based support. In our opinion, it is best to have a “special blend” of both, and have a team of professionals in place to make the call, or in some instances, don’t make the call.
