One reason that IT consulting can be so essential for a business or enterprise is because IT experts are skilled at looking past the minutiae associated with daily workflow in order to see the big picture. A case in point is the improved efficiency that businesses can experience by upgrading from Microsoft Exchange 2003 to Exchange 2010. As companies are increasingly striving to do more with less, they need to upgrade to the tools that will give them the most "bang for the buck," and a consultant familiar with the ins and outs of various configurations is well-placed to offer timely and informative advice in this regard.
The big picture for an enterprise includes more than just making sure that employees have access to needed programs. Also essential is making sure that programs consume only as many resources as necessary so that waste can be eliminated. Exchange 2010 allows businesses to save on power consumption as compared to Exchange 2003, while at the same time delivering an enhanced user experience.
For example, mailboxes in 2010 can be configured to allow 1024 MB of data, allowing employees access to far more of their email history at a time; the previous upper limit was 250 MB. Yet mailboxes in Exchange 2010 do not consume four times the electricity even though they offer four times the storage. Indeed, the electrical consumption of the new mailboxes averages approximately half of what it was before, producing a net savings to the business for the lifetime of the network while Exchange 2010 is deployed.
