The primary objective of the IT department is to support the growth and smooth operation of the business unit or of the entire organization. This implies that IT must ensure new applications are rolled out quickly and reliably, applications are up and available to users, and that application response times to the users are acceptable. IT has to accomplish this with as low a budget as possible with the fewest number of people possible; they have to be productive and efficient. The mantra of “do more with less” can be heard in nearly every datacenter operation around the globe.
