Plans can give you a certain idea of the direction in which you want to go and near future plans might be helpful to see, if business goals are met. But as detailed description of where exactly you want to be at, they are not useful anymore. Technologies are evolving too fast.
Expect the unexpectedWhatever trend might develop, there is no way of forecasting the future. It has to be standard, to expect the unexpected. This trend will increase through the influence of the digital natives. Are you already prepared that these workers want to create their workspace according to their personal needs. Maybe everybody will be downloading apps on his workspace to work efficient and effective. Just like with the iPhone. Are you already developing an internal app-store for your business?
Work together, not isolated
It is not appropriate anymore to have isolated groups that are responsible to develop the IT strategy or the like. The IT department has to be more open: Intern as well as towards the end user. As part of the consumerization of IT the end user needs to be granted more influence. On the market you should monitor blogs and consultants in order to compare trends and find possibilities to improve your IT strategy. The advice of suppliers and vendors has to be treated with caution, since they only promote products they can sell.
