Some companies choose to increase their focus on their primary business processes by outsourcing parts of their IT systems such as central or distributed systems. Other companies have chosen to go all the way and have an external provider take care of all IT activities to avoid the financial strain of complex, risky technologies in-house and in turn have security and lower IT related costs. By contracting close strategic alliances with a number of customers, DCS has achieved considerable success in managing the customers' combined IT facilities.

The strategic alliance is in itself a main concept, as it is a considerable step for any company to have the combined IT resources outside the company. This is why DCS focuses sharply on the human aspect, which is just as important as the financial aspect. Outsourcing is a sensitive process in which all parties must support the decision.
