Even if there is no immediate business benefit from a specific experimental technology, keeping up with the technology curve poises you to successfully understand, implement, and incorporate technologies that can increase productivity, performance, and profitability.
Deploying a new technology as a part of your enterprise infrastructure introduces the same reliability and availability requirements that you have for any other technology that you currently depend on. However, it also introduces new support, maintenance, and education requirements for IT staff to manage and support the day-to-day use of the new technology, as well as the creation, incorporation, and adoption of new IT processes across your enterprise for longer-term issues such as disaster and recovery planning.
