5 reasons why I chose Google Apps (in no particular order);
Features - I want the latest tools/features and don't want to have to wait or worse still pay to upgrade licenses/hardware/staff to get them, while waiting.
Reduce overheads - Both time and money, why allocate my staff hours to backup/patching/hardware maint of internal infrastructure when I can get it done for me for less.
Cope with growth - For us we have five mail office locations in the world, this was two just two years ago and with the same growth planned in the next two. I need a solution which I don't have to throw a lot of infrastructure at to react to this grow, most times I don't get the warning to plan.
Collaborative tools - The geographically diverse nature of the workforce is hard to support, but when they want collaboration to replicate being in the same room as they work on the same projects I need tools/features/technology which enables that (without costing the earth).
AppsCare - From the first meeting there was a good feeling about the kind of people we were dealing with. Having a senior technical specialist in the first meeting gave a very good impression that any question could be answered. Considerably less 'salesy' than others we talked to and that was encouraging while still able to give me the numbers/answers I needed.
Smooth handover from pre-sales into post and also have demonstrated a flexibility to how the project is run, we defer to knowledge but are not bossed into doing things.
The result was a smooth transition to Google Apps and a saving of £47,000.
to see how.
